This one’s for you - but I forgot to ping you;)
I just wish some of you brainiacs would apply what you know about past evolutionary changes in the size & structure of animals to a discussion on the future physique of humans, in say (?) 200K years.
If we stop smoking, eating meat, have no means of transportation, cannot walk outside because of global air pollution, have sexual confusion and use only Government pre-selected ova and sperm to procreate in labs, continue to sit at computers to communicate, what form will homo sapiens take?
My guess is we will look very much like Roswell aliens.
Im going to sleep now;)
In 200,000 years, almost everyone will look quite a bit like the modern population of India, with a some eastern Asian eyefold and European freckles and recessive hair colors thrown in — unless, as Blam noted, there is some kind of worldwide catastrophe extinctifying large areas of the planet in some unpredictable fashion.
May you find your way as pleasant.
