So, maybe new medicines.
Maybe GMO for Mars that can tolerate periodic drying and also radiation.
Maybe even someday humans with greater tolerance for radiation.

We Finally Know Where Humans and Neanderthals Interbred

I think I disagree that "Modern Humans came from Africa alone".  It is truer that African Humans evolved with less Neanderthal to a more modern form, and that Eurasians evolved to a modern form by the mixing of somewhat archaic peoples both from Africa and from the Neanderthals.

We should not despise our Neanderthal roots.

I don't like the term "Archaic" for these people and their ancestors or for the Neanderthals or Devonians or others.

Modern Eurasian humans do not have archaic genes, and neither do the Africans.  If the gene is in us, then it is modern.

There seem to be several interesting adaptations that may be useful in space.  I have previously noted Low Oxygen tolerance in Tibet and the Andes.  Also, there is an adaptation for diving in one people with an enlarged Spleen.

Some high latitude peoples may have adaptations to low light conditions and perhaps also for snow blindness.  And the low light conditions may also be associated with brain differences for the visual to help see in low light conditions.  The enlarged eyes were used by Neanderthals, Blue eyes may also function better in low light situations, but less well in bright light.  Just on a guess, perhaps some eyelid shapes may help with snow blindness.

So, I am very happy to consider the possibility that in the far future humans in space may have feet that are partially adapted to climbing.

Space humans may end up having any or all of these adaptations.

At first, I think humans in artificial gravity will need 1 g force synthetic gravity.  But I think that ultimately feet adapted for lower gravity could be helpful, once a way could be found to keep people healthy in lower gravity.

The 20th century seems to me to have been a time when certain peoples had a need to consider themselves as the "Best" form of human, I don't think that helped things much at all.
