last night in shiur we learned a fgascinating gemara about 'evolution' there were two guys having a bet to see if one can upset Hillel,( shabbos 31a)so the guy went to him and asked him 3 questions spaced out an hour in between each one. the first question was why to the babylonians have round heads, the second why do the tarvidim have weak (squinty)eyes, and the third, why do the afrikaans have wide feet. the answer to the first was they have bad midwives, the second they live in sandy areas and the third they walk a lot in the marshes rashi explains that "Hamakom" change them. so the discussion then is as follows, is Hamakom Hashem? or the place changed them? a few lines before this gemara is another one that discusses you shouldnt entertain people with stupid questions its a waste of time, so they discussed why hillel even answered thi guy.the maharsha says hillel understood this guy to be asking very deep questions why do the babylonians have big heads(why are they haughty) it says in pirkei avos that the bnai bilaam had three bad things they were haughty, had an evil eye, and one other. and he goes into a long 'arichus'. another meforash says that hillel answered because the questions ar edeep philosophical questions of the world? if all man is made from Odom then how can there be so many different types and colors of people. it must be that people adapt to their climate and he climate and environment can change a person. the rav brought a proof from mayer shuster who hangs out at the kotel and makes people frum, he said he's practically shvartz from being in the sun all day for 25 years. the afrikaans with wide feet i beleive rashi says its because they didnt wear shoes and shoes hold your feet together so if your barefoot your feet will flatten. so the question is is there a gene expression change in the foot of the afrikaans or only after going without shoes then their feet get wide...then we learned a gemara that says the entire galus of the world is becuase dovid hamelach accepted loshon horah about mefiboishes which then led to rechovaam and yerovaam splitting the kingshiop and yerovaam putting up idols and yada yada yada galus the power of words!
