(I figured there wasn’t a clear answer to this question, more of opinion/debate, hence the posting in this forum).
And creationists, please open another thread rather than hijack this one. This thread presumes evolution.
I was watching a National Geographic doco the other night where they did experiments on stone flies to work out the evolution of wings. Also an advert on TV where if the world was one hour old, humans as we know ourselves only appeared in the last hundredth of a second.
Which all means evolution must be pretty rapid. And presumably still happening, I can’t see why it would stop.
So my question is: how much are we humans still evolving, and is it detectable over the last few centuries/millennia? I know some theories posit that we are taller than our ancestors, but if that is due to nutrition does it count as evolution?
Then I thought about aliens. Tall, skinny, hairless, big heads, big black eyes. Maybe they are us in the future, grown puny from lack of physical activity, huge heads due to increased use of brain, hairless because I guess we are less hairy than our ape ancestors so are gradually balding as a species, big black eyes - not sure about that one - maybe only people with special eyelids get to survive a nuclear holocaust??? Maybe they are returning to us in time machines, not space machines, and their anal probes and other experiments are to extract our eggs and DNA to improve the species further (or “repair” it, should it have been damaged in some way).
OK now I am probably sounding mad. Never mind. My main question is serious though: how are we humans evolving, and how fast? And what do scientists expect us to look like in 1000 or 10,000 years time?
