In eastern Mexico’s underground caverns and streams, a blind fish undergoes a peculiar adolescence: as it approaches maturity, taste buds begin to sprout under its chin and on top of its head, creeping toward its back.

“It’s a pretty wild amplification of the sensory system of taste,” says Josh Gross, an evolutionary geneticist at the University of Cincinnati and a co-author of a recent study on the cave fish in Nature Communications Biology. Gross and his team discovered that the new buds blossom around the time when the fish transition from eating larval crustaceans to gobbling up their adulthood staple: bat guano. Taste buds outside their mouths might be helping the fish detect bat droppings in the utterly dark, “food-starved” caves, Gross says.

As folks who traverse the internet on a regular basis we have all come across people who have somehow managed to miss every scientific advancement made in the last century (or more) and just refuse to accept they are on the losing end of their own arguments. So, how do you handle these people?

Well, the most important thing is to NOT try and convince them you are right and they are wrong. In the following screenshots, you will see bits of a conversation on a tiktok video of someone I follow meant to adress this comment made on another of his videos. I won't show the whole conversation because, frankly, it's ridiculously long and shouldn't be but the poor person trying to refute him didn't know how to just...well, let the guy live in oblivion. They tried the poor thing.

Anyway, let's dive in with his initial comment:

I bet you can see where this is going. The video was a brilliant explanation on taxonomy and how we classify animals now (we no longer use Linnean classification as genetics have proven it simply doesn't work).

Now, this same commenter turned up in the comments to the new video with more biting stubbornness and some poor soul tried to make him see reason but I could tell from the start this guy wasn't gonna budge. So, how do you deal with someone who won't accept the facts? Use their own methods against them. Here's how you would approach some of the statements and questions this person puts forth in this insanely long debate.

Let's start with his original comment: reptiles never turned into birds.

Where is your proof? How do you know that statement is false? Can you prove it's false? Or, you can use his own words:

Now, for his first comment on the new post, I think oblivion nailed it. Stating that his one and only example of what differences there are is not a solid defense of his statement. You would then ask if he had other, more irrefutable examples and go from there.

Again, use his own words: "Since you won't accept the evidence fibsh has already put forth, what do you consider 'real evidence'?" Or maybe "What real evidence is there that you are related to you 100th great grandfather besides some written word?"

This one we don't answer with a question, more of a statement. Something like "well, yeah, everything has been interpreted by 'some guy'. A well known example is the Bible.

There's lots that can be brought up here like a list of mesotherms (animals that are neither warm or cold blooded but somewhere in between) such as crocodiles, tegus (technically a warm blooded lizard but I am tossing it in for funsies), leatherback sea turtles, tuna, great white sharks, some species of bees, naked mole rats, hyraxes, echidnas. Notice none of these are all in one group. We have "reptiles", fish, insects and mammals all listed. This just goes to show that body temp is not a good way to classify animals.

However, a guy like this will probably use his favorite catch phrase in this conversation:

Reptiles also are not the only animals to have scales. What about fish? Butterflies? Pangolins?

He claims that you can't use scales as a grounds for relationship (even though he just said all reptiles exclusively had scales) so then ask him "what is a ground for a relationship then?" Make him explain his statement.

This one can be a bit tongue-and-cheek: hell yeah, we're both mammals so we are distantly related. Don't even acknowledge the rest. Agreeing with their statement will confuse the stubborn soul.

Two things I can say to this, one using his own arguments:

Fact: it is your opinion that evolution is an opinion. Give me evidence to back up your claim.

Again, what proves a relationship?

Three times he makes exceptions to this unspoken rule (we think he's using Linnean reasoning but it's a bit hard to tell as he kind of goes all over the place). So I would ask "How many exceptions can be made before the rule is considered invalid?"

Continuing on from his first exception he asks:

So, what do you do when they ask for an answer after arguing a bunch?

"Why? You've haven't accepted any of the other viable scientific evidence given why would this instance be any different?"

I mean, you look like your family, don't you? (And yes, I am including extended family and ancestors) Where is your evidence that you can't know something had offspring? We can only trace human DNA back 10 generations so how to we know they reproduced beyond that? Oh...right, we all exist. (Sarcastic line probably should be left out but I couldn't help myself).

By that logic, identical twins would be considered the same person.

You...you recognize this and don't see ANY connection...AT ALL? And to the second point:

Of course, when he does actually use this he doesn't give any evidence to back up any of his arguments so...bring that up as much as possible.

I thought evolution was pseudoscience. Or only when it doesn't support your opinion?

You weren't alive in the 1940's to collect data so did the Holocaust actually happen then?

What proof do you have? They aren't even attached to anything...(hint, he things they need them to mate).

Then explain why gharials looks so different from all the other crocs.

Do you know what an expert is? It is the opposite of an amateur...which is what you are.

Oh boy...wait till you find out about Mandarin Ducks (they can't breed with other ducks).
