The secrets of fossil teeth revealed by the synchrotron: A long childhood is the prelude to the evolution of a large brain

Science Daily - Paleontology - Wed, 11/13/2024 - 11:31
Could social bonds be the key to human big brains? A study of the fossil teeth of early Homo from Georgia dating back 1.77 million years reveals a prolonged childhood despite a small brain and an adulthood comparable to that of the great apes. This discovery suggests that an extended childhood, combined with cultural transmission in three-generation social groups, may have triggered the evolution of a large brain like that of modern humans, rather than the reverse.

New insights into the Denisovans: New hominin group that interbred with modern day humans

Science Daily - Paleontology - Fri, 11/08/2024 - 10:33
Scientists believe individuals of the most recently discovered 'hominin' group (the Denisovans) that interbred with modern day humans passed on some of their genes via multiple, distinct interbreeding events that helped shape early human history. Scientists outline evidence suggesting that several Denisovan populations, who likely had an extensive geographical range from Siberia to Southeast Asia and from Oceania to South America, were adapted to distinct environments. They further outline a number of genes of Denisovan origin that gave modern day humans advantages in their different environments.
