No evaluation has not stopped it is constantly going on. The man of today is physically week but but intellectually strong whereas men or bygone ages were bigger and stronger but less intelligent in general. Women's bodies have changed a lot. Women of today cannot normally give birth without operation but women of even 50 years earlier even gave birth at home without much medical aid. It will go on; but we really do not know how the ultimate man will look like.
I can imagine man 1000 years hence to have a very big head but a very small and frail body moving around with the help of machines; actually he may make himself a part of a machine in which he may live permanently till he dies.
