Bison come in both genders, so why are the fossils we find normally male? The biases often tilted towards males, but sometimes — as in the case of bats — the bias was for females. More collecting runs up against an obvious concern in a world where species both beloved and crucial to their ecosystems are fading out of existence: How many animals, exactly, is too many to remove from their natural populations?
