What is the most ancient species that is still alive?

>>2680100

There isn't a definitive answer because all species evolve constantly, and how different something can be and still be considered the same species is ultimately arbitrary.

But for a less pedantic answer... Horseshoe crabs? Basically unchanged for 450 million years.

Idk, probably some archaea/bacteria below the bottom of the sea.

Jellyfish & Keith Richards

Chroococcidiopsis Thermalis is a pretty old version of cyanobacteria. Not sure if its the oldest, but it is pretty far up there.

I don't know how to interpret your memeing.

Turks, haven't evolved since the dinosaurs - about the same communicative skills as well. Fuck even their referendum was grunt once for yes, grunt twice for no

some "extremophile" microbe that predates cyanobacteria maybe

Don't worry, they probably didn't know what they were actually trying to say anyway.

Isn't this a /sci/ question? Paleontology is a discipline of natural history which doesn't really fall under the scope of /his/.

Yeah let's make Hitler threads instead you fucking faggot after all we have so few of them.

There's no need to be rude, you hurt my feelings.

At what point was the first human born? There is none. Every child is only a little different from their parents, it would be rare for them to have 1 mutation that would comprise the majority of human DNA in the future let alone 2 or a meaningful number of mutations.

So it follows that every single descendent in our evolutionary history should be considered a human and thus is within the scope of /his/.

Do you not know the defintion of history & humanities? Biology is not either, fyi.

And history begins at the chronicling of human deeds, not with the first human.

escaping from the jaws of a dinosaur is an impressive deed and biology plays an important role in history

1. Irrelevant
2. Yes, and so does the currents of the ocean and clashing tectonic plates, but that doesn't mean hydrology and geography are historical subjects.
