my response is way to long to post here.
quick bullets:
-- Technology has forced us into cerebral evolution moreso than physical. Out though process has jumped leaps and bounds over our physical development whichtakes thousands of years to emerge.
-- Our ability to manipulate ourselves and our environment has slowed the visible or measurable evolution of the humans species.
-- Neccessity is the mother of invention.....if you look around at what has been needed by our species to survive you will see tons of evolution. it may not all be physical but it does exist in spades.
lets look at some evolutionary u turns:
--why do we all (ok..most of us) need sunscreen to go outside for any length of time? We dont go outside any more.... This trait manifests itself inside of one life cycle so it cant be called de-evolution but if enough of us continue to spend most of out lives inside, our levels of melanolin (or whatever it is called) will eventually decrease to the level where we are forced out of the sun forever
-- done a complete pull up lately or climbed a rope or wall? If we keep perpetuating a sedentary lifestyle, none of us will be born with the correct amount of muscle potential to get out of a sticky situation is something goes wrong with out automated and convenient environment.
BTW I am pasty, nearly translucent, fat bastard so dont think I am soapboxing for physical fitness...just making points
oh and our species needs to be reduced by at least 60% to have any hopes of surviving more than another 500 years or so....

All humans lived in smaller nomadic groups as hunter-gatherers until around 10,000 years ago. The ability of medicine to correct anomalies has arisen within the past 100 years, although unnatural selection has certainly been around a lot longer. Regardless, our current state is merely a blip in the timeline of human development, and a speck on the evolutionary chain, making it impossible to predict where the species will go from here.
With that said, we are experiencing evolution at speeds far greater than any species has in the past.. it's called cultural evolution, and it's probably a larger decider of our future than any natural physical changes that may arise.

I just wanted to comment on the 6 toes idea. If you have genetically "evolved" into having 6 toes.......cutting the toe off doesnt fix that genetic "deformity" If it truly was an evolutionary trait it would continue on with your children.

I thought so too. Since modern technology has slowed natural selection so much, I assumed we stopped evolving. Nevertheless, I just read this article.

I guess we still are evolving. Perhaps it affects different aspects of us...but evolution is not something that can be stopped.
