Skeletal remains of Homo antecessor.
It's been quite a day for learning about our ancestry, with the publication of not one but three major studies.
They include new information about some of our most significant fossil finds, and a report on the retrieval of the oldest-ever human genetic data set. Where to start?
In the first
paper, in the journal
Science Advances, researchers describe taking brain imprints of fossil skulls of the species
Australopithecus afarensis (famous for "
Lucy" and the "
Dikika child'') that shed new light on the evolution of brain growth and organisation.
The international team, led by Philipp Gunz and Simon Neubauer from Germany's Max Planck Institute for Evolutionary Anthropology, scanned the Dikika child using synchrotron microtomography at the European Synchrotron Radiation Facility in Grenoble, France.
The results show that the brain of
A. afarensis, which lived more than three million years ago,
was organised like that of a chimpanzee but had prolonged brain growth like humans. That means it had a mosaic of ape and human features, a hallmark of evolution.
The study also resolves a longstanding question of whether this species had a prolonged childhood, a period of time unique to humans that allows us to learn and grow.
"As early as three million years ago, children had a long dependence on caregivers," says senior author Zeray Alemseged, who discovered Dikika in 2000 and now runs the
Dikika Research Project in Ethiopia.
Comment: So the WHO or World Health Organization (or those pulling its strings) has a long track record of giving vaccines with hidden ingredients known to be detrimental to those who would receive it. Consider this the next time some vaccine is created that everyone "must" have. Behind it may be a very malevolent agenda.
