MicroCT scans of the Australopithecus fossil known as Little Foot shows that the brain of this ancient human relative was small and shows features that are similar to our own brain and others that are closer to our ancestor shared with living chimpanzees.One of the things that comes out in the paper is how much reorganization of the cranium we share with the higher primates, suggesting that quite a bit of brain evolution occurred prior to the Last common ancestor. The paper is currently free (at least I had no trouble accessing it) at http://dx.doi.org/10.1016/j.jhevol.2018.11.009. If not, the abstract is.
While the brain features structures similar to modern humans -- such as an asymmetrical structure and pattern of middle meningeal vessels -- some of its critical areas such as an expanded visual cortex and reduced parietal association cortex points to a condition that is distinct from us.
This is a blog detailing the creation/evolution/ID controversy and assorted palaeontological news. I will post news here with running commentary.

Science Daily had a story just a bit back about research done on the new information surrounding the Little Foot australopithecine remains from South Africa. They write:
