Paleolithic Papers #27

Genus Homo:

Scientists are still stumped by the evolution of human breasts.

Hominins in Levant hunted different prey than did the resident hyenas.

H. sapiens:

Pleistocene hunters in Sri Lanka had a taste for monkey meat that lasted a long, long time.

East African hunter gatherers appear to have had a common ancestry.

There are more missing ancestors in our genome other than Neandertals and Denisovans.

Did modern humans self domesticate?

H. neanderthalensis:

Neandertals primary food source was, in fact, meat, at least, at Les Cottés and Grotte du Renne, in France.

What was the impact of the interglacial climate changes on Neandertal diets at Baume Moula-Guercy, Ardèche, France?

The replacement of Neandertals by modern humans was a little more complicated than what used to be thought: there was some, erm, intermingling.

Footprints of Neandertals from Gibraltar have been found.

Some are going hmmm over the stone artifacts at Châtelperronian.

Did inbreeding help do in the Neandertals?

Neandertals walked just like modern people did.

Sima de los Huesos Hominins:

The Middle Pleistocene hominins from Sima de los Huesos had very Neandertal-ish brains.

Denisovans:

Who were they? John Hawks comments.

H. erectus:

Britain may return the iconic Kabwe skull to Zambia.

Genus Paranthropus:

P. robustus:

What was the genetic origin of the pitted enamel hypoplasia in P. robustus?

Genus Aridopithecus:

A. ramidus postcranial remains from Ethiopia get a description.

A. ramidus had adaptations for waling bipedal.

META:

Is the African Eve hypothesis wrong?

Why did menopause evolve?

One paleoanthropologist's hopes for a human evolution museum in Israel.

Human and nonhuman primate brains are compared for clues to human brain evolution.

What were the origins of human language?

The tale of the multiregional hypothesis and the out of africa hypothesis are told.

Can we determine which hominin teeth came from when found?

The current 'gap' in the middle Pleistocene is very important to human evolution.

Root growth for teeth is compared between humans and apes.

Ardipithecus Teeth Found in Miocene Neogene Ethiopia?

Late Miocene hominin teeth from the Gona Paleoanthropological Research Project area, Afar, Ethiopia

Authors:

Simpson et al

Abstract:

Since 2000, significant collections of Latest Miocene hominin fossils have been recovered from Chad, Kenya, and Ethiopia. These fossils have provided a better understanding of earliest hominin biology and context. Here, we describe five hominin teeth from two periods (ca. 5.4 Million-years-ago and ca. 6.3 Ma) that were recovered from the Adu-Asa Formation in the Gona Paleoanthropological Research Project area in the Afar, Ethiopia that we assign to either Hominina, gen. et sp. indet. or Ardipithecus kadabba. These specimens are compared with extant African ape and other Latest Miocene and Early Pliocene hominin teeth. The derived morphology of the large, non-sectorial maxillary canine and mandibular third premolar links them with later hominins and they are phenetically distinguishable and thus phyletically distinct from extant apes.
