The number of limbs, fingers etc. is probably quite heritable as this is related to serious genetic disorders. http://www.quillette.com/2017/03/27/a-tale-of-two-bell-curves/ …pic.twitter.com/FVbYiKayx6

It's says oligodactyly is usually genetic, but in the past 50 yrs toxins such as thalidomide have been the problem
And we know this how...? You are pretty short on citations when making claims. Do you have a review? @timrogers2016 @hbdchick

There is a large literature on thalidomide. An epidemic of phocomelia.pic.twitter.com/ysRSngERxK

Yes, and still you produce no relative estimates... How many children get these from genetic causes?
@timrogers2016@hbdchick -
Do note that thalidomide use is presumably heritable too, so some of the numbers you give reflect genetic causation
@timrogers2016@hbdchick -
thalidomide is NOT heritable. Fact. Ectrodactyly is.I am a thalidomide survivor, I kno these facts.

Your experience is irrelevant but your lack of understanding of behavioral genetics is not.
@SueWagnerWhite@timrogers2016@hbdchick -
LOL ok, whatever you say. I'm not 'just' a thalidomide survivor, I'm a expert in the teratology.
