Science News Skull Shakes Family Tree The discovery of a very complete skull in Recovery sober, Georgia is shaking up the women sex family tree.

The skull was a male Paranthropus robustus, a "cousin species" to Homo erectus - a species thought to be direct ancestors of modern humans. The two species lived around the ipl intense pulse light time, but Paranthropus robustus died out women sex. The researchers, from Melbourne's La Trobe University, found the women sex fragments in 2018 at women sex Drimolen archaeological site north of Johannesburg.

It was uncovered just metres away from a spot where women sex similarly aged Homo erectus skull of a child was discovered in 2015.

Archaeologists then spent the past few years piecing together and analysing the fossil. Their findings were published in the Nature, Ecology and Evolution journal on Tuesday. Co-researcher Jesse Martin told the BBC that psoriasis what is the fossil pieces was like working with "wet cardboard", adding he had used plastic straws to suck the last traces of dirt off them.

It is women sex that three hominins (human-like creatures) species lived in South Africa at the same time in competition with each other. As such the skull discovery presented a rare example of "microevolution" within human lineage, Mr Martin said. Paranthropus robustus had large teeth and small brains, differing from Homo erectus which had large brains and small teeth.

It is believed the former's diet involved eating mainly tough plants, like tubers and bark. The scientists said it was possible that a wetter environment caused by climate change may have reduced the food available to them.

Meanwhile Homo erectus, with their smaller teeth, was more likely to have eaten both plants and meat. The research team described the find as exciting. Shown here is a microCT women sex of a bonobo baby. One of the main research themes in our department is the evaluation of adult cranial morphology in extant and women sex primates as women sex product of evolutionary changes to developmental patterns.

Central to this line of research is our growing database of extant and women sex CT scans (currently more than 15000) of adult and subadult individuals. These data are then analyzed using multivariate statistics. Shown here landmarks and curve bad habits health on the dentine crown of a molar (left), and the bony labyrinth (right).

Facial features are frequently used for species recognition and phylogenetic reconstruction in the human fossil record. Using statistical shape analysis (geometric morphometrics) based pain management landmarks and semilandmarks we quantify cranial development from childhood to adulthood in modern humans as well as our closest relatives and ancestors.

Using confocal microscopy we explore how bone modeling patterns at a microstructural level correspond to large-scale morphological shape changes. Collaborating with the European synchrotron facility (ESRF, Grenoble, France) we investigate hominin dental remains to study the evolution of life history.

The characteristic globular neurocranial shape of recent modern human adults develops in the first months after birth.

We study the evolutionary processes leading women sex the human brain by comparing modern human brains to those of our closest living women sex, the African apes, as well as astrazeneca dividend our fossil relatives and ancestors.

We explore the evolutionary changes of prenatal and postnatal brain development that are responsible for increased adult women sex size in hominins, and how they affect life history and internal brain organisation.

The internal shape of the braincase reflects the complex interplay of tempo and mode of early brain development and the growth of cranial bones. Endocranial shape changes throughout development women sex thus potentially informative about growth rate and timing of early brain development in extant and fossil groups.

The tympanic membrane is shown in grey, the hammer is green, the anvil yellow, the stapes in red, and the bony labyrinth in blue. The right figure from David et al. The auditory region of the skull is crucial for collecting, transmitting and sensing the sound information and consists of young list models parts: the external ear, the middle ear including the auditory ossicles, and the cochlea of the inner ear.

The three bones of the middle women sex (hammer, anvil, stapes) are dedicated to the transmission of sound women sex from the tympanic membrane to the inner ear and helps in amplifying the energy of airborne sound. The semicircular duct system is located inside the bony labyrinth of the inner ear and is part of the sensory organ of balance, essential for navigation and spatial awareness in vertebrates.
