Becoming Human

A paper in the journal Science this week offers evidence of the as yet oldest human occupational site in the New World. The site is Cooper's Ferry in Idaho and radio carbon dating yields an age range of 16560 to 15280 years ago. The authors, Davis et al.

A technique to tease out the dietary history of fossilized hominins    has been used with some of the more recent hominins in the human lineage, such as  H. sapiens and H. neanderthalensis.

A technique to tease out the dietary history of fossilized hominins  then  has been used with some of the more recent hominins in the human lineage, such as  H. sapiens and H. neanderthalensis. In a paper published in the 15 July Edition of the journal nature, a team led by Renaud Joannes-Boyau reports on the use of this technique with two fossil specimens from the species A.

Two fossils found in Apidima Cave southern Greece,  in the early 70s have yielded startling results after undergoing reanalysis, according to a paper published in this week’s edition of the journal Nature and named Apidima 1 and 2.  The paper is entitled “Apidima Cave fossils provide earliest evidence of Homo sapiens in Eurasia” by Harvati et al.

A widely reported hominin jawbone, found in a Tibetan cave and dated to 160,000 years ago, was announced this week. The fossil jawbone was identified as" Dennisovan", according to the investigative team. The dating of the jawbone was ascertained by the UT (uranium-thorium) method.

This fossil is significant in a number of respects:

Announced in the April 10 edition of the journal Nature is a new species of genis Homo, named Homo luzonensis. The attribution is based on a small number of post cranial bones and seven teeth. The latter show both primitive and derived characteristics. The remains are dated to approximately 67,000 years ago by the Uranium thorium (UT) method.

Plio-Pleistocene artifacts have been found in Algeria, according to a paper in the journal Science this week. Heretofore, late Pliocene-early Pleistocene stone tools were known from East Africa exclusively.  In a paper headed “1.9-million- and 2.4-million-year-old artifacts and stone tool–cutmarked bones from Ain Boucherit, Algeria”, Sahnouni et, al. disclose their findings.

Widespread cranial injuries characterized both Neanderthals and anatomically modern humans and thus are not unique to American football, a study in the journal Nature concludes.

Cueva de los Aviones is a cave system in  Spain in which have been found  decorated sea shells. These have been dated to 115,000 years ago and are attributed to he Neanderthal occupiers of the site, it was announced in the journal Science Advances of 22 February 2018.

Dating was  accomplished by Uranium series technology.

A paper appearing in the journal Nature this week announces the discovery of figurative cave art dated to  approximately 40,000 years ago. In addition there was also found a hand stencil (the outline of a human hand) dated to 51,000 years ago. These are the earliest finds of figurative rock art, according to the authors of the paper, M. Albert et al.
