dude. u got to seperate science and also pseudoscience.
science is something that is proven in peer reviewed journals where as pseudoscience is just something some whack scientist came up to milk money out off (eg. magnetic therapy)

neways in human evolution. nothing can be said. all of us humans will evolve and the evolution is very small and minute. like Caucasians have higher enzymes that can metabolize alcohol, or the shorter limbs and bigger torso mass of the eskimo's to retain body heat.

to the lowered osteoporosis rates in the malay community which has a stronger javanese genes rather than an equal combination of java and oriental genes.

but what concerns me is that. weak genes that should not have survived is being passed on because of human selection and the feeling of Pity which leads to accumulation of faulty genes like the fragile X syndrome or down syndrome and hemophilia.

in nature these genes will die out giving way for better, healthier and stronger offsprings.
but because of human intervention these genes persist.

for example the hemophilia gene in the british royal family.
