How Human Bones Reveal the Fallacy of a Biological Sex Binary
Science keeps showing us that sex also doesn't fit in a binary, whether it be determined by genitals, chromosomes, hormones, or skeletons.
Alexandra Kralick is a Ph.D. student in anthropology at the University of Pennsylvania. She studies the growth and development of sex differences in the great ape and human skeleton in the subdiscipline of biological anthropology. Her previous work is on gorilla dental development and wrist bone shape. Kralick is a National Science Foundation Graduate Research Fellow.
