The function of early hominins’ enlarged brow ridges, and their reduction in size in Homo sapiens, have puzzled paleoanthropologists for decades.

Three members of a gene family called NOTCH2NL may have been involved in the evolution of humans’ big cortex.

The retention of ancient hominin DNA in modern human genomes may have helped our ancestors adapt to life in diverse environments. 

Symbiotic gut bacteria evolved and diverged along with ape and human lineages, researchers find. 

Remnants of fires indicate modern humans may have lived around the same time as Homo floresiensis.

The 700,000-year-old teeth and jawbones of small hominins may be the oldest remnants of Homo floresiensis.

A new analysis of stalagmites stacked deep within a French cave suggests that the ancient hominin was capable of planning and carrying out construction projects.
