Meanwhile early human fossils dating more recently to 160,000 years ago - at Herto in Ethiopia - had big 'robust' faces - unlike us - but with 'globular' braincases
The researchers will look closely for skeletal signs of hybridization in the animals, which might include changes in the shape of the nose and braincase
London, June 14 ( ANI ): A new analysis of the braincase
of a 290-million-year-old fossil fish that has long puzzled paleontologists has revealed that the common ancestor of all jawed vertebrates on Earth resembled a shark.
When Alan Pradel of the MusE[umlaut]um National d'Histoire Naturelle in Paris CAT scanned the 300-million-year-old fossilized iniopterygian from Kansas, he and his colleagues saw a symmetrical blob nestled within the braincase
The primitive fish's softer skeletons did not fossilize well, leaving scientists few braincases
or other parts to study.
They've compared computerized braincase
reproductions for Flo, 9 people with microcephaly and growth retardation, and 10 regular-size adults.
These include long, narrow braincases
and short, thin faces, a pattern akin to that of modern inhabitants of southern Asia and South Pacific islands.
Although the Dmanisi braincases
are surprisingly small, they nevertheless represent a regional variation of H.
had been broken into fragments and the limb bones shattered.
This holds for the size and shape of Ngandong braincases
, the thickness of the cranial bones and other features, he points out.
However, even at the time of its discovery's announcement in June 2017, researchers said the shape of its braincase
, or cranium, indicated that the human (https://www.mpg.de/11322481/oldest-homo-sapiens-fossils-at-jebel-irhoud-morocco?c=2249) brain had evolved since.
