Animal Shapes

There are basically no anatomical differences in both of these stances. The biggest difference is that the stance on the right is more energy conserving than the ‘classic’ anthro stance on the left. From a evolutionary perspective anything anatomically that wastes energy is unlikely to give that individual an environmental advantage. 

For that reason, and the aesthetic look, I much prefer to give my characters the stance on the right.

I know that this may feel very bad in the moment, but this is actually an incredibly important skill to have. You have stumbled upon a skill that takes some artists a very long time to develop… the ability to see your own mistakes!

I understand that this is making you feel unsure about your artwork. I think its important to remember this graph (click for source):

The short explanation of this is as follows:

Your skill at creating art and skill at seeing and evaluating your art develop separately. It seems like you are stuck in an “Art Low” because your perception is continually developing faster than your ability. What is important to remember is that your artistic ability is absolutely developing too, and your perception is vital to the development of your ability.

Ok, this aspect aside, I think the other thing we need to conquer here is the feeling of worthlessness when we perceive our art as “bad”. I know it is incredibly hard to do this. 

Some affirmations that I find very beneficial are:

-When I am learning, the results don’t matter. All that matters is that I’m learning.

-When I see a piece as a failure, it does not make me a failure. I have succeeded by creating in the first place. Each failure will teach me something new.

-My worth as a person is not based around what I produce or how productive I am.

Now for a bit of practical advice:

-Write down the mistakes you see every time you look back on an old piece. For example, if your far eye tends to drift away or get too small, write that down. If your feet tend to be too small, write that down. Now, every time you start a new drawing, look over the list of common mistakes and purposefully focus on finding references for those areas. If you have a friend you trust, give that friend a copy of your list and ask them to point out to you when you are making those mistakes. This will give you the ability to strategically “flush out” your common mistakes until you are focused and no longer make those mistakes. You will always have a full list, but it will be ever-changing because as you bring attention to a common mistake, you will focus on it and flush it out.

-When you sit down for a study session, focus specifically on the weaknesses you found the last time you looked at an older drawing.

-If you are looking for classes or resources, specifically target your areas of weakness.

In general, approaching your weaknesses strategically will give you the reigns back over your art. Rather than saying “this drawing looks wonky now but I don’t know why”, figure out exactly what was unsuccessful in your drawing. Bring focus to those areas every time you sit down to draw.

The Following text is copied from the thread of the official twitter of fightforthefuture.org:

@fightfortheftr (April 19, 2018): There have been a lot of inaccurate reports that the FCC’s repeal of #NetNeutrality will officially go into effect next week on April 23rd. That’s not true. It’s a bit more complicated than that. Ready? Here we go:

Its understandable many journos are confused by this. It’s legitimately confusing. The FCC order said it would go into effect 60 days after publication in the Federal Register, which would have been April 23rd. But, it still has to be approved by the Office of Management & Budget.

There was another FCC filing in the Federal Register that would imply the earliest the OMB could approve this (and its worth noting that approval is basically just a technicality) is actually April 27th, but its likely to happen some time after that, possibly even weeks after.

The most important thing for EVERYONE to understand is that nothing catastrophic or dramatic is going to happen immediately when the FCC rules go into effect. Telecom shills will immediately start saying “See? The sky didn’t fall, we never needed #NetNeutrality.“ 

They’re lying.

The ISPs aren’t going to immediately start blocking content or rolling out paid prioritization scams. They know Congress and the public are watching them. Rather, the death of #NetNeutrality will be slow and insidious. You might not even notice it at first.

And that’s the worst part. What will happen is over time ISP scams and abuses will become more commonplace and more accepted. They’ll roll out new schemes that appear good on their face but undermine the free market of ideas by allowing ISPs to pick winners and losers.

Over time we’ll see less awesome startups. Less awesome videos. Less diverse online content. And we’ll see more content that our ISPs want us to see. The Internet will be watered down and manipulated. It will change forever in ways that harm our democracy. 

But it will take time.

So: don’t fall for ISP lobbyists talking points. They’re ALREADY claiming that #NetNeutrality was never needed since the sky hasn’t fallen, and the rules haven’t even gone into effect. But also don’t panic. The Internet is not going to die next week. Keep calm and keep fighting.

The Senate will vote in a matter of weeks on a Congressional Review Act (CRA) resolution to block the FCC’s repeal. Now is the moment to get engaged.

today is Nov. 15. the FCC, under chairman Ajit Pai, will not listen to the public despite millions of comments in support of net neutrality. They are going to try their hardest to kill net neutrality, which in turn will kill the internet, which in turn will help eradicate democracy. it won’t just affect Americans, it has the potential to affect the entire internet, something we ALL use daily. you can bet your ass other countries will see america doing this, and use it as an excuse to do it in their own countries.

this is what buying a plan without net neutrality looks like there:

you have to pay MORE for features you’re already guaranteed to have under net neutrality. and in america, you already know how expensive everything is.

democrats AND republicans both want net neutrality. advocacy groups in touch with congress have said that if your members of congress receive calls from you, they are more encouraged and more likely to take action to stop Pai’s plan to gut net neutrality. after Nov. 22, it will be MUCH HARDER to convince your member of congress.

please, call them. call them daily.

In truth sexual characteristics are diverse and varied and do not always match up with sex chromosomes; also, a sexual “binary” of sorts is not constant amongst all living things, and most organisms have other systems of reproduction. 

Furthermore, gender is the suite of societally-defined social roles and behavioral characteristics that is typically assigned based on the externally perceived sex of a child; and does not actually have anything to do with biology - even less so than sex. Even though it is assigned based on this externally perceived sex, a person’s gender does not have to remain with the one assigned; much as we don’t determine people’s careers based on who their parents were anymore, your birth has no limitation on who you are and what gender identity you construct for yourself. Since it is a societally defined construct, people can and do construct more than the two traditional ones, and all are valid. 

Just because you cannot handle your societally constructed worldview surrounding sex, gender, and genetics being dismantled by sociology & biology itself doesn’t mean, additionally, that you have the right to make other people feel unsafe and uncomfortable - in short, that you have the right to remove people from moral consideration - simply because you don’t like having your world view being dismantled. Believe it or not, the complexities of human behavior & the diversity of sex and reproduction in life cannot all be covered in a simple high school biology class. 

So next time you want to say “didn’t you pass biology” remember: a biology PhD student, who graduated from the University of Notre Dame with an actual degree in Biological Sciences, has reminded you that you’re wrong. 

There are more than two genders. 

You: Somehow thinks they know more because you took a couple of classes

I mean, I know that in school they teach you a very clean, concise, definitive way of doing things and you’ve probably learnt something like the definition of a species is a population of organisms that are able to reproduce and produce viable offspring, or something. But I mean literally anyone who has done even undergrad biology can tell you that that statement is incredibly reductive and incredibly controversial in the scientific community [1][2]. In fact, you probably don’t even need a background in biology to spot the obvious flaw in the logic there, which is the fact that organisms classified as different species do reproduce and produce viable offspring. Quite a lot, actually. Lions and tigers (Panthera leo and P. tigris), coyotes and grey wolves (Canis latrans and C. lupus)… In fact, there’s even a word for new species arising through hybridisation between existing species - hybrid speciation [3]. The great skua (Stercorarius skua) is believed to be an example of this in animals [4], and another interesting one that may be pretty much hybrid speciation in action (though not nearly anything that can be called a new distinct species yet) is the so-called “Eastern coyote”, a population of wild coyotes in the eastern US that are mixed with grey wolf and domestic dog, and can contain as much as 40% non-coyote DNA [5]. 

And, in fact, the ability of two organisms to reproduce and produce viable offspring actually has very little with how we choose to classify them, because evolutionary and genetic relationships are rarely that simple. For example, some species that are the same genus - e.g. horses (Equus ferus) and donkeys (Equus africanus) can interbreed, but their offspring are usually sterile [6], while other species that are different genera to each other can interbreed to produce intergeneric hybrids, some of which are even fertile (for example crosses between false killer whales (Pseudorca crassidens) and bottlenose dolphins (Tursiops truncatus) [7], or between king snakes (genus Lampropeltis) and corn snakes (genus Pantherophis) [8]). Most “exotic” domestic cat breeds (e.g. Bengals and Savannahs) also fall into this category - for some reason felids are genetically Weird in that a wide variety of species in the family Felidae seem able to interbreed with each other, no matter how different or distantly related they are. I mean…

Look at this shit. Now bear in mind that the domestic cat (Felis catus) is known to be able to interbreed with species in the caracal, ocelot, lynx and leopard cat lineages in addition to those in its own lineage, and if that wasn’t bad enough puma/leopard hybrids are a thing that exist. Those species aren’t even in the same subfamily, let alone genus or genetic lineage - the leopard is classed as subfamily Pantherinae, genus Panthera (P. pardus) while the puma is classed as subfamily Felinae, genus Puma (P. concolor). 

[9]

Although these aren’t even the most distantly related species that are able to interbreed - domestic chickens (Gallus gallus domesticus) are known to hybridise with guineafowl [10], and the offspring of these crosses are interfamilial hybrids since chickens and guineafowl are classified in different families (chickens belong to family Phasianidae, guineafowl to family Numididae).

And of course another place where the “able to interbreed and produce viable offspring” definition falls apart is with organisms that reproduce asexually or without the need for a sexual partner, which is even more complicated when you consider that some species (for example, some species in the paraphyletic whiptail lizard genus Cnemidophorus) are dioecious, meaning they have separate sexes, and reproduce by producing gametes via meiosis, but have actually lost the ability to reproduce sexually somewhere along the evolutionary line - these species reproduce predominantly or entirely by parthenogenesis (essentially a form of self-cloning) and the Y chromosome has been entirely lost in the population. This also ties into hybrid speciation because it is believed that these parthenogenic species arose from hybridisation between two or three sexual species [11][12], leading to polyploid individuals (i.e. those with ‘extra’ sets of chromosomes) - for example, the all-female parthenogenic species Cnemidophorus neomexicanus is actually a hybrid of two sexual species, Cnemidophorus inornatus and C. marmoratus (or C. tigris, according to Wikipedia), and thus new individuals of this species can be formed either by parthenogenesis in a single C. neomexicanus parent, or sexual reproduction between a male and female C. inornatus and C. marmoratus/C. tigris [13]. Some female parthenogenic species are also able to interbreed sexually with males from sexual species, resulting in hybrids which may or may not also be parthenogenic [14].

So you can ask, well what the fuck is a genus, or a species for that matter, if it doesn’t necessarily indicate whether two animals are genetically similar enough to interbreed or not? And, more to the point, is there a strict set of quantitative criteria that defines whether two populations of organisms are classified as the same or different species? And I mentioned speciation, which brings up the question, when exactly in the process of evolution does one species actually become another?

The thing is, there aren’t actually definitive answers to these questions - if you ask a bunch of biologists what a species is, it’s likely you’ll get different answers. “Species” also has a number of definitions [15][16], mainly depending on the type of organism being studied and the angle it is being studied from. For bacteria, for instance - where “similar enough to reproduce” really isn’t applicable - I think the general consensus is that individuals are grouped together if their genetic similarity to one another is 97-98% or higher, while a similar definition of “organisms that are highly genetically similar to one another” tends to be used for asexually reproducing organisms such as some plants, and parthenogenic animals like whiptail lizards or Bdelloid rotifers (which does of course raise the question of what exactly “highly similar” means - any decided-upon cutoff point will necessarily be somewhat arbitrary). Such groupings of organisms may be referred to as phylotypes to distinguish them from the reproductive definition of a “species” [17]. Likewise, a lot of ecological writing will define species and speciation according to reproductive isolation, which isn’t necessarily synonymous with reproductive compatibility - reproductively isolated populations may be genetically able to reproduce, but be prevented from doing so or unlikely to do naturally so due to differences in geographical location, habitat or behaviour (think lions and tigers). These are some of the many different “types” of species, with either competing or overlapping definitions of what exactly constitutes a species in each case:

Morphological or typological species (morphospecies)

Phylogenetic species

Evolutionary species

Genetic species

Genalogical concordance species

Reproductive species

Autapomorphic species

Ecological species

Recognition species

Phenetic species

Isolation species

Cohesion species

…You get the idea.

For vertebrates, I think generally the two most used definitions are the biological species concept (BSC) and phylogenetic or cladistic species concept (PSC), which differ in their criteria for what they consider a species [18][19]. PSC, for example, doesn’t include a subspecies category while BSC does - and thus, some organisms that are classified as subspecies of the same species under BSC are either classified as different species or are lumped together as the same species under PSC. For example, grey wolves and domestic dogs. The domestic dog is/was often considered a separate species to the grey wolf, for obvious (morphological/behavioural) reasons - the wolf was Canis lupus, the dog C. familiaris - but since dogs are descended from wolves (a now-extinct lineage of wolves, not modern grey wolves [20], but Canis lupus nonetheless) they are more properly classified as a subspecies, C. l. familiaris. Likewise, having also ultimately descended from wolves, the dingo is officially classified as C. l. dingo, although there is some debate about that - at one stage I remember it being classified as a “subspecies” of domestic dog, Canis lupus familiaris dingo (and it’s still, to my knowledge, widely considered to be descended from domestic dogs [21][22], in which case the second name would be more correct), while still other people classify it as a completely separate species, Canis dingo [23]. You can see why species boundaries and definitions can get murky, especially when the exact evolutionary origins of a particular animal are unknown or hotly contested.

In fact, canids as a whole are kind of a mess when it comes to phylogeny. How many species of wolf there are really depends on who you ask - some populations traditionally classified as subspecies of the grey wolf, for example the Indian wolf (traditionally C. l. pallipes), the Himalayan or Tibetan wolf (traditionally C. l. chanco) and the Eastern wolf (traditionally C. l. lycaon) have been suggested instead to be classified as separate species - Canis indica, Canis himalayensis and Canis lycaon, respectively [24][25]. Likewise, just last year it was discovered that what was thought to be an African subspecies of the golden jackal (Canis aureus) had in fact been misidentified and was instead an undiscovered species of wolf, now the African golden wolf (Canis anthus) [26]. And then there’s also the fact that, despite being called “jackals”, the black-backed and side-striped jackals actually aren’t very closely related to the golden jackal, or indeed to any of the rest of the genus Canis [27]. In fact, going by the cladogram below, you can see that the African wild dog and dhole - both of which are classed in their own, unique genera (Lycaon and Cuon, respectively) - are actually placed closer to wolves, golden jackals and coyotes than black-backed and side-striped jackals are, even though both of the latter species are considered part of genus Canis (the black-backed jackal is C. mesomelas and the side-striped is C. adustus). Many sources also say that these two species differ from the rest of the group in that they have only 74 chromosomes, while wolves, coyotes, golden jackals, African wild dogs and dholes all have 78. This makes the moniker of genus Canis somewhat useless when trying to determine exactly how genetically similar these animals actually are to one another.

[28]

And this isn’t even touching the issue of the “red wolf” (Canis rufus), a critically endangered so-called “species” of wolf closely related to the grey wolf, eastern wolf and coyote, which more recent molecular and genetic analysis has revealed may simply be a wolf/coyote hybrid [29]. Of course these classifications aren’t set in stone, either - new studies and discoveries are constantly uprooting and rewriting our knowledge of phylogenetic and evolutionary relationships among species. Sometimes it’s also pretty much impossible to accurately represent the relationships between similar-but-distinct populations using only the terms “genus” and “species”, which is where alternate concepts like species complex, subgenus and superspecies come in.

Another feature of evolution and speciation that makes classification difficult is what are known as ring species, in which a series of neighbouring populations of organisms may evolve divergently (i.e. undergo allopatric speciation) in such a way that each geographically adjacent or overlapping population can interbreed with the next, but the last population in the “ring” has diverged to the point that it can no longer interbreed with the first (basically, population A can interbreed with population B, B with C and C with D, but D can no longer interbreed with A). 

[30][31]

When does the actual split occur, and at what point in the ring can we consider the populations to be different species? We just don’t know. (And in some cases this is considerably more messy and complicated than even the ring species model makes it seem [32]). The point is, though, that there is no definitive, universally agreed-upon cutoff point at which we can say with certainty that two organisms have evolved sufficiently as to become different species, any more than you can definitively say where along a rainbow spectrum of colours red becomes orange or orange becomes yellow. The decision whether to lump or split taxa becomes even more arbitrary in paleontology than it is with extant species [33][34] - when you’re working with an incomplete fossil record and pretty much going entirely on morphological similarities since genetic or molecular analysis often isn’t possible, there isn’t really a way to conclusively determine whether that specimen you found represents a new species, a new genus, or is simply a larger/smaller/juvenile/unfortunate-looking version of an already-described animal. Many specimens now believed to be juveniles of previously-described species were originally believed to be completely new ones - for example, Nanotyrannus is now often (but not universally) agreed to be a juvenile Tyrannosaurus rex [35], and Dracorex and Stygimoloch are considered immature specimens of Pachycephalosaurus [36]. And then there was the whole deal where Brontosaurus didn’t exist for a while and then it did again and it was all very confusing [37].

Obviously, at the end of the day, a zebra is materially different from a dog in the same way that, to get back to the original topic, a penis is materially different from a vagina (actually a bad analogy since homologous reproductive organs are much more similar to each other than taxa that have been separated for millions of years, but anyway). The biological differences and similarities themselves exist, but any attempt to categorise and quantify them will necessarily rely on socially constructed and frequently arbitrary models, definitions and assumptions. That’s basically what science is - a continuous (and frequently wildly inaccurate) attempt to try to make sense of reality. We often attempt to understand or make predictions about reality using mathematical or quantitative models of the situation or by sorting things into sets and categories, which is useful and necessary in many cases but is also often far too simplistic to be taken as any kind of gospel truth regarding the actual nature of reality, because simply put reality doesn’t care for or abide by human-made rules and categories. Essentially, we’re trying to find quantitative ways to represent things that are by nature qualitative, and that’s always going to be arbitrary to some extent. Obviously biological characteristics (whether genetic, sexual/reproductive, etc.) objectively exist and would continue to exist if humans and human culture were to suddenly disappear, and in that sense, things like sex, gender and taxonomic classification can be said to be based in biological reality. But human attempts to define or categorise these characteristics - for example species concepts, the binary model of sex, etc. - are not in themselves biological realities, and are subject to change based on new information. For example, evolutionarily speaking, “reptiles” (as we traditionally understand them) don’t exist [38]. Obviously this doesn’t mean that lizards, tortoises, snakes, crocodiles, non-avian dinosaurs etc. don’t exist or never existed. It simply means that the socially constructed classification of animals into two distinct, mutually exclusive groups called “reptiles” and “birds” is completely arbitrary and not actually the result of any inherent biological reality (in fact the opposite).

I mean I know how crappy the highschool biology syllabus can be @valarie-lynn so I’ll also link you to the Wikipedia page on species and the species problem, and also to some more on sex and how it’s just as complicated and arbitrary as the concept of species (from Actual Biologists™) if you’re interested. I’ll also leave you with a quote from Charles Darwin:

“From these remarks it will be seen that I look at the term species as one arbitrarily given for the sake of convenience to a set of individuals closely resembling each other, and that it does not essentially differ from the word variety, which is given to less distinct and more fluctuating forms. The term variety, again, in comparison with mere individual differences, is also applied arbitrarily, and for convenience sake .” [39]
