The meticulous excavation, cleaning and scanning of the skull of the ~3.67 million-year-old fossil specimen has revealed the most complete Australopithecus adult first cervical vertebra yet found. A description of the vertebra by Wits University researchers Dr Amélie Beaudet and the Sterkfontein team was published in the Scientific Reports.

The first cervical vertebra (or atlas) plays a crucial role in vertebrate biology. Besides acting as the connection between the head and the neck, the atlas also plays a role in how blood is supplied to the brain via the vertebral arteries.

Because "Little Foot" is so well-preserved, blood flow supply to the brain could also be estimated for the first time, using evidence from the skull and vertebrae. These estimations demonstrate that blood flow, and thus the utilisation of glucose by the brain, was about three times lower than in living humans, and closer to the those of living chimpanzees.

So their heads moved more like birds? Or more like chimps?

They were more mobile supposedly to help them climb into trees more easily.

It looks like that of monkey. I wonder how we will look in future 

I imagine more and more hairless so I honestly think men and women going bald is just our genes getting ready for the next step in human evolution...men will all be bald in the future
