A team of researchers from Italy, Spain and Georgia has found the remains of ancient hunting dogs at a dig site in what is now modern Georgia. In their paper published in the journal Scientific Reports, the group describes ...
Counting feels utterly effortless to adults, who are unlikely to even remember when or how they picked up this useful, apparently automatic skill. Yet when you think about it, counting is a remarkable invention. It helped ...

Unlike early human species, chimpanzees do not seem to be able to spontaneously make and use sharp stone tools, even when they have all the materials and incentive to do so. That was the finding of a study of a total of eleven ...

A million years ago, dry seasons became more frequent and forests retreated before the encroaching savanna. Meanwhile, clustered around a nearby lake, our ancient ancestors fashioned stone tools.

Homo sapiens See text for extinct species.
Homo is the genus that includes modern humans and their close relatives. The genus is estimated to be about 2.5 million years old, evolving from Australopithecine ancestors with the appearance of Homo habilis. Appearance of Homo coincides with the first evidence of stone tools (the Oldowan industry), and thus by definition with the beginning of the Lower Paleolithic.
All species except Homo sapiens (modern humans) are extinct. Homo neanderthalensis, traditionally considered the last surviving relative, died out 24,000 years ago, while a recent discovery suggests that another species, Homo floresiensis, may have lived as recently as 12,000 years ago. Given the large number of morphological similarities exhibited, Homo is closely related to several extinct hominin genera, most notably Kenyanthropus, Paranthropus and Australopithecus. As of 2007[update], no taxon is universally accepted as the origin of the radiation of Homo.
