Modern human skeletons, with our lightly-built form, evolved only relatively recently, after the start of the Holocene about 12,000 years ago and even more recently in some human populations, according to a study that used high-resolution imaging of bone joints from modern humans and chimpanzees as well as from fossils of extinct human species.
A study of associations between stone tool evidence and fossil hominin remains shows that a wide range of species made stone artifacts.
Social scientists believe that pre-Homo human ancestral species, such as Australopithecus africanus, used human-like hand postures much earlier than was previously thought.The authors say they have the first archaeological evidence for stone tool use among fossil australopiths 3-2 million years ago.
The news media might be heavily biased toward evolution, but at least it is predictable.
PvE/Alamy Our distant ancestors may have swung from branches and knuckle-walked like a chimpanzee – challenging recent thinking that the earliest hominins did neither. That is the conclusion of an analysis of 4.4-million-year-old Ardipithecus ramidus, thought to be one of the earliest known hominins. A. ramidusthat was published in 2009. One well-preserved individual – nicknamed Ardi – had bones that suggested it typically walked along branches like a monkey rather than swinging below them like a chimp. This hinted that our last common ancestor with chimps also walked along branches, ...
