I read someplace, and I can't remember the percentage, but it's mind bogglingly high.  Something like 99.9% of all species that ever existed have gone extinct.  Animals too bizarre to imagine are kaput.  What the thing didn't say is that all species are constantly evolving.  It's just that for all practical purposes, nothing evolves out of the species stage.  If you look at it statistically, our chances for survival are nothing short of dismal, even if we don't turn out to be the engineers of our own extinction.

Depending on when you arbitrarily set the beginning of mankind, we could say that hundreds of thousands of years of evolution led to something so specifically well adapted to our current environment.  And it was just all a waste of perfectly good DNA.
The open question right now is whether (or how much) our ability to create localized environments with artificial heat and cooling in otherwise hostile environments impacts our evolution -- we no longer have to evolve to fit a niche, we can create our own suitable niche wherever we like.

Also, the technology is not far off for being able to edit human genes prior to in vitro fertilization.  We could -- by accident or by design -- create our own successor species.  I think it's going to be a long time before embryonic human genetic editing is approved, however.

That may be the case here in the U.S.A., but there's a big scary world out there where people don't give a crap what the U.S.A. likes or doesn't like. If it's possible, I expect someone, somewhere, will do it.

Korea claims they already do it.  England already combines human DNA with other target animals (including sheep).

I would like to hope that both -- we ought to have evolved into something definitely not homo sapiens by then.

We will probably be homo sapiens for a very long time.  Our evolution in the standard sense is likely over.  We are the only Homo left and not likely to speciate.

Not until we permanently occupy the Moon and Mars and have permanent space settlements, no.

Thinking of "Belters"?  I bet we don't live that long (its going to take longer than we think to get "out there" routinely.  I hope I'm wrong, but I won't be around to know.

Should we give it any credence?

I didn't say anything about when... I don't expect to live to see permanent settlements anywhere other than maybe on the Moon, and that'll be a Chinese base because we can't get our shit together.

But once humans are living off Earth permanently, that's by definition a new environment that they will evolve to better suit, even if it's only the gravity -- or lack thereof.
