Will humans ever evolve into a species, that can bot live in air and water? After all, we started off in the sea! johnwyn

I rather doubt it - evolution only works when the species is unaware of it, as soon as a species becomes intelligent enough to care for it's weaker members (thus allowing them to breed) instead of letting them die out, it stops evolving.

I'm not coming out in favour of Eugenics, but if a different species started to evolve out of humankind - we'd wipe it out.

That's doesn't mean that we couldn't develop a human that could breathe underwater, but it would be done by surgery not by genetic engineering. There are some people around now who want to replace their perfectly good natural organs & limbs with electro-mechanical prosthetics - they claim this would bring them closer to perfection, sounds a bit like the Borg to me.

Or of course we go through something like Waterworld. or GillyWeed becomes the substance of choice

Gillyweed only lasts for an hour tho', could make swimming the Channel underwater a bit hazardous.

Species on Earth might one day become species in space. If so, the space might already be full of that kind of new species.

It wouldn't look like an astrounaut, though, but something quite different.

From water to air, from air to space, sounds logical.

We will evolve and adapt to climate change and the enviroment, hense if a human could survive on Jupiter, and given enough time over generations, a species of evolved human would be born, to adapt to the enviroment of Jupiter, e.g. being able to cope with the mass of gravity being exhereted on the body by jupiters gravity! So we evolve according to the enviroment, or gradual genetic alterations, within the DNA and genes!

Every time we use contraception, we demonstrate that brains can thwart Darwinian designs.

So snap that rubber on chaps, and change the world.

I belive that humans will evolve but not to a flying achine or to a fish but probbably ower brains will evolve to produce telecenisis and other brain powers, the fact that peole know about evolution makes no difference it probbably helps evelutin as we wont kill the the new species thinking it's the Devil.

Actually, there is some evidence to suggest that the reason our brains are so large is because we were shore dwellers, and we ate a lot of sea food. Sea mammals have larger brains than their cousins on the plains. By eating less sea food our brains may well be shrinking and we are actually getting more stupid as time goes by. Ha ha!
