New fossil discovery sheds light on the evolution of the human hand

By Philip Guelpa, 26 February 2014

The discovery of a fossilized hominin metacarpal bone in Kenya demonstrates that the evolution of a key adaptation of the hand, thought to be associated with sophisticated tool production, occurred much earlier than had previously been known.

The genetic legacy of the Neanderthals

By Matthew MacEgan, 6 January 2014

Evolutionary links between the development of language and stone tool technology

By Philip Guelpa, 19 November 2013

The use of sophisticated imaging techniques demonstrates that regions of the brain used in language production and stone tool manufacture overlap, suggesting an evolutionary link in the development of cognition.

New fossil skull find may revolutionize view of early human evolution

By Thomas Douglass, 22 October 2013

A newly reported skull from the site of Dmanisi in Georgia demonstrates wide variation in brain size and morphology within an early Homo erectus population, with implications for other fossil species and ancient population structure.

New research sheds light on a key dietary change in early human evolution

By Philip Guelpa, 14 October 2013

Multiple studies of carbon isotopes in fossil hominin teeth from southern and eastern Africa document the change from woodland to grassland diet which marked a major step in the evolution of early humans.

Study finds mammals diversified only after the extinction of dinosaurs

By Philip Guelpa, 22 February 2013

A major study using both fossil and genetic data has produced a detailed reconstruction of the ancestral placental mammal and supports the interpretation that the great adaptive radiation of mammals took place only after the extinction of dinosaurs.
