There is even an old theory that modern day humans are neotenous products of a proto-ape-man. A list usually follows of those characteristics that humans share with infant modern apes: less hair, larger head to body ratio, shorter arms, less muzzle, etc. Then 'futurists' grab hold of that and imagine current human babies as our adult future; is that how the bug-eyed hairless 'gray alien'[1] arises, or the 2001 "star child"?
