Paleoanthropology

#1

Post by isha »

It's just not going away so I will have to make a new thread, different than the archaeological thread.
And what better to start with than a discovery that threatens to upend the accepted theories...

An 8.7 million years old skull that MAY suggest the out of Africa theory is not accurate. I love the way this area of study is always being changed by new discoveries.
Previous reports claimed that our human ancestors originated in Africa. However, a newly discovered skull from an ape suggests we evolved from Europe.

Human Ancestors Evolved From Europe, Not Africa
The skull of Sahelanthropus tchadensis, which is thought to be the earliest known species in the human family tree and may have existed up to seven million years ago, is the primary source of the widely-held belief that our ancestors developed in Africa.

However, the skull of an 8.7 million-year-old ape discovered in Turkey indicates that they originally came from Europe. The skull belongs to an ape named Anadoluvius turkae that has just been discovered. It is considered the first specimen of early hominines, including humans and African apes

According to scientists, the skull shows that hominins spent more than five million years in western and central Europe before migrating to Africa from the Mediterranean. The current study is based on examining a partial skull discovered at the site in 2015 that is remarkably well-preserved and has most of the facial structure and the front section of the brain case.

The results are detailed in a study co-authored by an international team of academics led by Professor David Begun at the University of Toronto (U of T) and Professor Ayla Sevim Erol at Ankara University, which was published in Communications Biology.

The skull was discovered at Cankiri, a Turkish city located about 87 miles north of Ankara, at the Orakyerler fossil locality. Anadoluvius, according to researchers, lived in a dry forest environment, weighed between 110 and 130 pounds, and probably spent a lot of time on the ground.

I enjoyed this discussion with Richard Dawkins and Bret Weinstein from a few days ago.
I disagree with some of the uncharitable comments - I thought they both behaved very well and argued their points in interesting ways and were generous and friendly with each other.

There's a lot of DNA research that suggest that the Out Of Africa theory is not exactly robust. Australasia seems to be a better candidate for some of the earlier developments. The OOA theory is a simple one and probably too simple for a highly complex evolution.

Yeah it's fascinating what is turning up and great to anticipate what will turn up. There was likely back and forth migration depending on climate. Such an interesting subject because it is always expanding

The funny thing is seeing people who think they are smart (typically opinion column "journalists") disparaging others as Neanderthals when most people throughout Europe and Asia have Neaderthal DNA. For much of the last few million years, there were ice ages and migration patterns would have been affected by those. There's even an "into Africa" theory with Neanderthal DNA appearing in North Africa but not beyond the Sahara as it acted as a natural barrier to migration. And there are others like the Denisovians. Human history and pre-history is very complex and simple explanations don't work well because archeology and DNA tend to destroy them (The Clovis Horizon theory in North America is a good example.)
