Is it true that social anxiety is a leftover trait from when we were cavemen?

If that’s true, it’s the most outdated, miserable design flaw ever. It serves ZERO purpose in the modern world. Why am I getting a full panic attack response just for making minor eye contact or stuttering over a word? It’s an absolute curse, and I hate it.
I seriously hope this trait eventually gets bred out of humans or fades away, because living with it is exhausting

Why are African animals so huge?

I live in Australia and the largest land animals I can think of here is probably a kangaroos and emus which really aren’t any larger than a human. But my family recently went to Africa and the diversity animals is actually crazy. So so so many large animals living in the same place side by side. Rhinos, elephants, giraffes, wilder-beasts, zebras, hippos, warthogs, buffalo’s, ostriches, lions, cheetahs, hyenas leopards and probably more that I forgot. I never really appreciated how big these animals were until I actually got to see them in person absolutely amazing. Australia and Africas climate is kinda similar in a lot of places. Why is our country ecosystem dead in comparison?

Forests of Madagascar 1000 years ago would have been a truly magnificent sight

I was recently watching the awesome show prehistoric planet and it was truly crazy to me. Giant 1 tonne avian dinosaurs in modern times! Laying eggs larger than even the biggest dinosaurs. And before there were giant lemurs the size of gorillas. Not to mention terrestrial crocodiles capable of hunting on land. Little bit frustrating how close these incredible creatures got to making it into the present day only to be wiped out when humans arrived. It should serve as a lesson to us of how fragile island ecosystems can be.

Hypothetical If a homo erectus was teleported to today and I stabbed and killed it would I be charged with murder or animal cruelty?

FYI - I am NOT planning on killing any homo erectus’s this is purely a stupid thought that popped into my head recently

If Neanderthals did persist into the present day wouldn’t we just view them as another race and not a seperate species?

If the physical and mental differences between Neanderthals and us were so huge than how did we manage to interbreed with each other and produce viable offspring who’s genes/lineage were SUCCESSFUL enough to survive in virtually all people who aren’t of African decent. Im aware the fact that we are capable of hybridising does not in of itself disprove that we are seperate species given that some species today can hybridise but still it is incredibly confusing.

The physical differences between the average human today and Neanderthals are absolutely within normal human diversity. Just because their jaw is bigger and have a more prominent brow ridge they’re somehow a different species to our own (I’m aware those aren’t the only differences).

But Take the Dinka people of South Sudan who sometimes produce individuals over 7 feet tall. Look at their frame and their bone thickness. Now compare that to the people of Timor-Leste in Asia who walk around only a little over 5 feet tall with a completely different frame. Hypothetically imagine both these races went extinct thousands of years ago and palaeontologists got ahold of both of their bones/fossils. The differences in skeletal structure, frame size are huge. And in real life the differences are even more pronounced with them having completely different skin colors, hair types, facial features ect. To me it seems very possible that in this situation applying the same classification logic we used with Neanderthals we could call them as seperate species even though in real life they aren’t.

And GENETICALLY humans and Neanderthals are extremely similar and many geneticists don’t even think they are a different species to our own. We share a common ancestor at most around only around 600,000 years ago. Generally speaking species often take several MILLIONS of years to diverge.If they did evolve into a seperate species in this time then that would indicate extremely fast speciation.

But honestly I think Neanderthals should better be thought of as an extinct race/ ethnic group of humans or at the very least subspecies of Homo sapiens rather than extinct seperate species. Though in a way they aren’t really extinct because a lot of us even me are partly descended from Neanderthals and their lineage is still very much alive today.

Another thing to note is that the scientists who find these supposed new humans “species” also have a vested interest in classing them as such even if they really aren’t since they certainly gain fame notoriety and probably money

If climate change caused the ice age megafauna to go extinct then how did African megafauna survive?

If climate change was indeed the cause of the extinction of megafauna then wouldn’t it follow that Africa’s megafauna would have been similarly affected since the climate change was global and affected every continent?

How likely is it that some dinosaur survived the mass extinction but then just subsequently went extinct?

Since the fossil record in incredibly incomplete and there were likely thousands of species of dinosaurs across all corners of the planet is it reasonable to believe that at least one species of (Non bird) dinosaurs survived the mass extinction like say for a couple million years afterwards but then just went extinct later on. After all we know that birds survived so why couldn’t other have as well

Where do looksmaxers get these drugs?

A lot of looksmaxers talk about the importance of low inhibition. Lot of them say they take medications such as pregablin or blaclofen to lower their anxiety/inhibition. My question is these drugs are prescription only. So do they get it by just bullshiting to their doctor or do they likely obtain it illegally or something. I’ve tried searching for an answer and I’ve got nothing.
