How could they tell?

(From here.)

But what about . . .

Those Swedish archeologists must be mistaken. After all, who are you going to believe: a team of experts, including a member of the U.S. Armed Forces Medical Examiner System’s Armed Forces DNA Identification Laboratory (AFMES-AFDIL), as well a forensic geneticist and others, who after carefully and scientifically examining human remains determined they were of a woman; or an anthropologist with a Ph.D. no less, in a classroom in an American college who claims it is impossible to determine the sex of human remains? Sadly, in the US we have no choice but to believe the latter.
