Paleolithic Papers #23

Genus Homo:

The modern human hand was almost certainly around by 500,000 years ago, predating modern humans by 300,000 years.

The deactivation of the Cmah gene two to three million years ago appears to have given hominins a leg up by increasing endurance and improving running speeds.

H. sapiens:

When DID modern humans reach southeast asia and sahul?

The revised timeline of data from the Liang Bua cave may suggest modern humans made it to Flores by 46 kya.

The Levant had a humid period between 44kya and 55 kya.  That may be what helped modern humans disperse out of Africa.

An abstract piece of art appears to have been found in a cave in South Africa dating from 73,000 years ago.

Using ZooMS to understand the bone tools of the twilight of the Pleistocene in North Africa.

Humans actually share better than other primates.

Beer before agriculture.  Maybe.  However, beer dates from the twilight of the Pleistocene in Israel.  If not older.

Neandertals:

The early dates for the Neandertal Art might be wrong.  Some are disputing them.

Could cooking and fire be how modern humans outcompeted Neandertals?

How much did the climate cycles impact the replacement of Neandertals by modern humans in Europe?

Neandertal brains were bigger than modern humans, but not necessarily better.

Denisovans:

Meet Denny.  She is a 13 year old girl who had a Neandertal mother and a Denisovan father.

The cave where Denny came from has given up 4 more bones (not hers).  Dr. John Hawks comments.

Aroeria Hominin:

The bony labyrinth of this hominin appears to be more primitive than in Neandertals.  This could be a new hominin or an example of Homo heidelbergensis.

META:

Evolution of the hominin foot and how it relates to bipedalism.

How DID humans evolve their 'smarts?'

Two to three million years ago, human ancestors had genetic change that improved their running capability.
