Paleolithic Papers #32

Genus Homo:

H. sapiens (modern humans):

Stone tools have been recovered from Cooper's Ferry, Idaho (USA) dating from 16,000 years ago.

Was the basal most H. sapiens surprisingly modern 500,000 years ago?

Human hearts evolved for endurance.

Foot prints have been found on Calvert Island, British Columbia dating from over 10,000 years ago.

H. neanderthalensis (Neandertals):

There was a shift at a single site of how stone tools were made during Late Acheulian the at Caune de l’Arago.

Did modern humans and Neandertals keep interbreeding over a long period?

Did the Neandertal Eustachian tube contribute to their extinction?

Neandertals were more innovative with their tools than normally credited.

The Neandertals footprints give insight into their social lives.

How Neandertals used birds, including their feathers, in the Qesem Cave, Israel.

Denisovans:

Denisovans seem to have had fingers more like modern humans than Neandertals.

Using genetics and epigenetics, researchers have reconstructed the shape of the face of at least one Denisovan.  The facial features are distinct from Neandertals and modern humans.

The introgression of Denisovan genetics into modern humans gave us an immunity boost.

Sima de los Huesos Hominin

At least one of the Simea de los Huesos proto Neandertals seems to have been murdered.

One of the hominins at Sima de los Huesos had a pathological growth for its ears.  It might not have made the individual deaf after all.

The cochlea evolution of the Simea de los Huesos Hominins gets examined.

H. naledi:

H. naledi's baby teeth were unique.

Genus Paranthropus:

P. robustus:

The femural neck of P. robustus gets examined.

Genus Australopithecus:

What were the Australopithecines?

Australopithecines seem to have breast fed longer than their contemporaries.

A. anamensis:

A nearly complete skull of A. anamensis gives a face to the species and shows evolution is messy showing even in hominins species often overlap in time.

META:

The trabecular boot gets examined in 4 different hominins.

Humans are unique in how they digest fatty foods.

Did a single gene mutation 3.3 million years ago make hominins prone to heart attacks?
