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.
I’m going to sleep now;)
We're not likely to be here. Some natural disaster, super-volcano, asteroid-comet impact, super-pandemic and etc will probably wipe us out. Only the humans who have made it to other celestial bodies will survive to repopulate the earth.
