brow ridges.

brow ridges would be showing,» says Chris Stringer of the Natural History Museum in London, a member of the team.

brow ridges and less robust skull bones, similar to early modern humans and some other Asian fossils.
The researchers discounted two theories commonly put forward to explain protruding
brow ridges: that they were needed to fill the space where the flat brain cases and eye sockets of archaic hominins met, and that the ridge acted to stabilise their skulls from the force of chewing.
The study contributes to a long - running academic debate about why other hominins, including our immediate ancestors, had gigantic
brow ridges while anatomically modern humans evolved flatter foreheads.
Seven new skulls, plus 10 others deposited in the pit at about the same time, have distinct Neandertal traits, including robust lower jaws, small teeth at the rear of the jaw, and thick
brow ridges with a distinctive double arch.
Big
brow ridges and teeth suggest that ancient Homo heidelbergensis (above) may have had more testosterone than modern Homo sapiens (left).
Males with generally higher testosterone levels are known to have thicker
brow ridges and cranial bones than men with lower testosterone.
While the study couldn't control for every variable that might have affected the shape of the skulls, the trend the researchers found was toward thinner craniums and less prominent
brow ridges starting around 80,000 years ago and possibly earlier.
THE odd leg bones and prominent
brow ridges of a fossil hominid found in Belgium in 1830 clearly belong to an ancient relative of Homo sapiens.
Fossil remains and anatomical reconstructions indicate that the typical Neandertal had a stocky muscular body with short forearms and legs, a large head with bony
brow ridges and a brain slightly larger than ours, a jutting face with a large nose, and perhaps reddish hair and fair skin.

brow ridges, flat noses, low - crowned heads and protruding muzzles.

Neanderthals sometimes seem like our defining Other, recognizably human yet not: Homo sapiens in a funhouse mirror that pushes the face forward yet obliterates the chin; inflates
the brow ridge yet compresses the skull; and bulks out the chest yet truncates the lower limbs.
After chimps started acting as if they saw themselves in the mirror, after about 10 days, he anaesthetized them and applied an odor - free red mark to a location on their faces they could not see, such as above
the brow ridge.
After four years of searching, he uncovered a skullcap with a simian - like
brow ridge and a large brain case, along with other fragmentary fossils, buried near the Solo River on the Indonesian island of Java.
The team analyzed the projection of
the brow ridge, facial shape, and cranial volume of 13 early Homo sapiens that lived before 80,000 years ago; 41 modern humans that lived 38,000 to 10,000 years ago; and skulls from a global sample of 1367 recent humans.
The skull shows a new mix of features not seen before in fossil humans — it has traits that link it to Neandertals, such as a fused
brow ridge, as well as some primitive traits that resemble other extinct fossils in Europe.
Using 3D engineering software, the researchers looked at the iconic
brow ridge of a fossilised skull, known as Kabwe 1, held in the collections of the National History Museum.
Then we simulated the forces of biting on different teeth and found that very little strain was placed on
the brow ridge.
Professor O'Higgins said: «We used modelling software to shave back Kabwe's huge
brow ridge and found that the heavy brow offered no spatial advantage as it could be greatly reduced without causing a problem.
The area behind the skull's thick
brow ridge (which suggests it was a male) is relatively flat.
Like the antlers on a stag, a pronounced
brow ridge was a permanent signal of dominance and aggression in our early ancestors, which modern humans traded in for a smooth forehead with more visible, hairy eyebrows capable of a greater range of movement.
«In apes, chimps, and gorillas, you have a big depression just behind
this brow ridge,» says Brunet.
«Since the shape of
the brow ridge is not driven by spatial and mechanical requirements alone, and other explanations for brow ridges such as keeping sweat or hair out of eyes have already been discounted, we suggest a plausible contributing explanation can be found in social communication.»
As for the Dinaledi finds, Schwartz and Tattersall point out that although the foreheads of some of the new skulls are gently sloped, one skull has a taller forehead with a distinct
brow ridge — suggesting two species are present.
