Height may be largely due to nutrition, but it's a biological distinction between now and 40000 years ago. To say we are identical biologically is wrong.
You seem to be confused about the difference between genotypes and phenotypes. Phenotypically, sure, you might be a little different from the modern humans that emerged some 200,000 years ago. Genotypically, you're the same. You're certainly the same as the humans that were around during the time of behavioural modernity about 50k years ago.
To say that changes in average height and muscular development is evidence of significant change in our species is just wrong. Bodybuilders display extreme differences in muscular development compared to average individuals. Are they evolving in a different direction to the rest of us?
