Recent advances in our understanding of human evolution challenge the way we currently name and classify our ancestors, according to new research from Monash University. The research, published in the American Journal of Biological Anthropology, argues that we need a rethink, and proposes reclassifying all species of humans and our closely related fossil relatives that have lived in the past 4-5 million years as part of the Homo genus. Human evolution is often presented as a straightforward progression through distinct species, from ape-like ancestors, through Australopithecus and earlier members of Homo, culminating in Homo Sapiens that live today.
