Paleolithic Papers #31

Genus Homo:

Apparently, there has been selection against the archaic components of the genome when interbreeding hast taken place between modern humans and other hominin species.   

Could cooking have shaped our evolution for the last 2 million years?

More articles about the two previously undetected hominin relatives people seem to have interbred with.

Rock art requires a relatively high density demographic.

Modern Humanity (H. sapiens):

Tetrapod Zoology goes into five "mysterious" cave paintings.

Two Patagonian volcanic caves have evidence of people for the last 19,000 years.

Late Pleistocene fossils of modern humans have been found across the Wallace Line.

Mesolithic fire pits from the Netherlands get studied.

Modern humans occupied the Ethiopian highlands sometime between 31 kya to 47 kya.

An infant burial was found from Late Pleistocene Morocco. 

Human presence evidence from the Upper Paleolithic of Joran.

Ancient tools suggest modern humans spread across Eurasia earlier than previously thought.

Neandertals (H. neanderthalensis):

Studying Neandertal brains may give insights to modern human brain evolution.

The virtual reconstruction of the Apidima-2 skull.

The paleogenetic analysis of the Gibraltar Neandertals shows two different populations separated by time.

Half of Neandertals suffered from surfers ear, strongly implying they spent a lot of time in the water gathering food.

A Neandertal tooth was found in the Zagros Mountains.

Denisovans:

Could the 3 rooted second molar in the first Denisovan mandible be morphological evidence of introgression into modern populations?

Did Denisovans intentionally carve and paint this rock?

Denisovans are starting to come into the paleoanthropological light.

Hobbits (H. floresiensis):

Meet the hobbits of Indonesia.

H. erectus:

The Koobi Fora site in Kenya gets more support for being evidence of early use of fire.

H. naledi:

Meet Homo naledi.

Genus Australopithecus:

A. africanus mothers appear to have nursed their children for at least a year.

Authors of a new paper are arguing StW 573's skull shows it to be a different species than A. africanus.

META:

Hominin fossils seem to indicate early human species had teeth development similar to modern humans.

A single gene mutation 2 million years ago might explain why humans are prone to heart attacks.

There were significant environmental changes in the Middle Pleistocene in Europe.
