But that doesn't mean Pulaski wasn't a man, Estabrook said.
"This is where the sort of social science distinction between sex and gender is actually really important, because everything we know about Pulaski's lived existence as a person bopping through life is that he was baptized as the son of his parents, and recognized as masculine all through his life," Estabrook said.
"What's interesting is that the skeletal remains that we have are showing that there was clearly something else going on with the secondary sex patterns of bone development in his body."
