Being A Metalhead Is My Gender

The half-circles are called zaï! They're a traditional farming practice in the Sahel desert, and their introduction + reintroduction can be largely credited to Yacouba Sawadogo, the man linked above! He reintroduced and innovated on the zaï on his own farm in the 1980s, and did extensive outreach (along with scientist Mathieu Ouédraogo) to encourage other farmers to adopt them as well.

He also promoted the use of cordons pierreux, which are basically just lines of rocks to reduce erosion, preserve sediments, and increase water absorption.

GRAVEWHALE!

Okay seriously this is some fascinating shit.

And I don’t know shit about fossils, marine biology or ocean research.

Females and males out of breeding plumage look like this:

Here’s a quick handy reference list or anyone who isn’t sure:

Homosexuality does exist in almost all social species.

“Alpha males” are not a real phenomenon and in fact the most aggressive males tend to be the least reproductively successful.

“Survival of the fittest” simply means that the success of a species hinges on how well it “fits” its environment. It does not mean that stronger or smarter individuals are supposed to succeed. Those things can even be a detriment in nature by wasting too many resources.

“Race” is not a biological concept. Someone who looks different from you has the same human genes, just a different grab-bag of dominant traits.

Evolution is not a march towards higher complexity, more intelligence or even more adaptability. It’s just a fluctuation of characteristics dictated by environmental pressures and mutation. A slime mold isn’t “less evolved” than a hawk, just adapted for success under different parameters.

People didn’t evolve “from apes.” It’s more complicated than that. We are a category of ape, sharing a common ancestor with the other apes.

No human on Earth is “closer” to an evolutionary ancestor than any other. We all descended from the same one.

Neanderthals were also a “sibling” species of ours. We didn’t evolve from them.

Humans are actually more genetically homogeneous than most people suspect. This is possibly due to a population bottleneck at some point in our evolutionary past. Two chimpanzees from different sides of a jungle are likely more genetically different to each other than any two human beings in the world.

Our big brains may help us use tools, but what was really principal in their development was the need for empathy, communication, and cooperation.

Humans. Are. Social. So social it drove an incredibly energetically costly increase in our brain size.  Don’t believe anyone who says its our nature to fight “every man for themself.” We’re humans, not bears. We fight for each other.

And we always have. Fossil remains are found of ancient humans who bore signs of crucial mobility impairments that lived to notable ages. Some even have sticks or other mobility aids – community care and support is our way. We don’t cast off those with impairments, we stand by them.

Human sexual dimorphism is on a decreasing trend. Our ancestors had greater difference in canine size and overall size. Our dimorphism gap has gotten smaller.

Occam’s razor is the principal that whatever is the simplest explanation is probably the most likely one. Don’t believe someone who says the reason we evolved bipedalism is so that males could carry gifts to females to woo them. Yes, this is a real ‘theory’ on how bipedalism evolved.

Skin tone is an adaptation of UV levels vs vitamin D levels. Both come from the sun. UV is harmful, so where sun is plentiful populations develop a darker skin tone for more protection. The skin needs sun to create vitamin D, so where sun is scarce, the skin tone lightens to allow more sun in. This is literally all it is.

Final thing: No one’s mind is really equipped to fully understand how long a billion years is, or a million, or even tens of thousands of years. Evolution takes place over a loooong time. Its very, very, slow, slower than we can really comprehend. We can’t “stand in the way” of natural selection by caring for our ill. We don’t need to “help” evolution in any way. It inevitably happens, but not on any sort of timescale we could possibly affect, so don’t fall for anyone that tells you not to “stand in the way” of natural selection. That’s fascism, and its utterly pseudo-scientific.

Human: We just train new people how to do it?

Elf: *gears visibly turning in their head*

Human: Are you alright?

Elf: I just realized that we didn’t have to let that whole city fall to ruin just because my grandfather died.

Human: My cousin made it.

Elf: Impossible! Those metalworking techniques were lost a hundred years ago!

Human: What do you mean lost? My great-grandmother learned to make these swords from an elven smith, then taught it to her kids.

Elf: That's ridiculous. No elf would give such secrets to a human.

Human: They didn't. Meemaw delivered the metal to the forge, and no one kicked her out when she stayed and watched. She always said they barely acknowledged her even when doing business with her, like she wasn't worth noticing.

Elf: Come to think of it, my great-uncle always was rather single-minded when he started working.

Human: So he wasn't ignoring her, he just forgot she was there?

#you don't need figurative immortality if you have literal immortality

oh wow the glass-tower office buildings we constructed when we thought air conditioning and central heating would never have downsides...have downsides?

and we're still building them?

while the Victorian house museum where I work, with thick walls and small windows and big wooden shutters stays ~10 degrees above (winter) or below (summer) the outside temperature for days on end with no help at all?

uh. okay then
