I don't know why members of the audience were laughing but I suspect it had something to do with ignorance and dogma.
They're students, and he's a Black professor. It doesn't take much.
Do you agree with the professor about male and female skeletons being indistinguishable?
Yes. Or at least, I agree with his actual statement, which you are of course misquoting.
You can make an educated guess about biological sex if enough diagnostically relevant remains are present, but there's no way to derive any knowledge about cultural categorizations of gender or gender identity from material remains alone. The question posed was whether you could tell the difference between a man and a woman two thousand years from now. No, you could not do so with certainty, and if they belonged to a culture that lacked a written record, your guess would be even less accurate as you would have no basis for hypothesizing how that culture regarded gender differences at all, let alone how those individuals were regarded when they were alive. This would be true for an anthropologist now, looking at the past in most locations at that time distance. But since in this case the question is about a future anthropologist, they would presumably have access to a plurality of written and video knowledge about our culture's strategies for defining gender, and as such they would be well aware that many of our modern day cultures and social classes acknowledge a gender trinary and the possibility of gender transition, up to and including a fair number of surgeries and therapies that would affect several of those diagnostic criteria. Ergo, they would know for
certain that their data could only ever lead them to a guess, of uncertain probability, even they had a very strong guess about biological sex, which is also not always the case. This is not unusual, in the real sciences, the possibility of uncertainty.
I love how she failed to so much as correctly
define anthropology as a field, yet believes herself to be more expert in the subject than her interlocutor!
