Running a relatively close second at 52 deaths a year are miscellaneous mammals including deer, horses, and pigs. Dogs are next with 28 human victims, and cows kill about 20, mostly farm handlers.
Homo (from Latin homō 'human') is a genus of great ape (family Hominidae) that emerged from the genus Australopithecus and encompasses only a single extant species, Homo sapiens (modern humans), along with a number of extinct species (collectively called archaic humans) classified as either ancestral or closely related to modern humans; these include Homo erectus and Homo neanderthalensis.
