Here’s Michael Woodley of Menie’s presentation this month on the old question of how smart were the Ancient Greeks. You can try turning on the subtitles (6th button from the right at the bottom of the screen) if you can’t hear. Woodley is a very interesting and very aggressive scientist. Whether there is enough ancient DNA data and accurate enough modern polygenetic scores yet to answer this question is beyond me.
But, at least eventually, we should know.
(When did Woodley add “of Menie” to his name?)
