Moscow, December 16 (Sputnik) .- The two genes inherited by our cousin evolutionists are likely to increase the size of the cranium and the brain.
Nowadays, our DNA fragments are the possibility to find out what Neanderthals are. In the case of African-Americans, this figure is generally between 1% and 2%.
While we are influencing a mechanism, we know that some Neanderthal genes may be useful, but others may lead to a certain tendency for certain diseases.
Recently, scientists demonstrated that the two pieces of Neanderthal DNA could have an effect on ourselves.
The research published in the current Biology journal was not about deciding how to influence the Neanderthal genes, where appropriate, the value of the research lies in the unprecedented view of genetic modifications that influence it. evolution of man's development
By moderating the volume of skull neanderthals, the researchers believed that the brains were as large as ours, above all, perhaps larger.
Philipp Gunz, according to the paleoanthropologist of the Leipzig German Evolutionary Anthropology Max Planck Institute, whose brain was not ours, is "rounded up" by "all other human species that stretch the brains." Dr. Gunz and his colleagues on tomography have studied the fossil skulls studied to keep the brain evolved. Modern skulls were rounded up by modern-sized brain regions. The research team ventured to find that the genetic modification of change could find an answer to the link between the modern humans and the Neanderthals and that the Neanderthals genes could compare the brain's human form to modern brain forms.
Compared to the shape of the brain, after joining Neanderthal genetic variants, two genetic markers jumped: people who developed themselves had unusual genetic activity patterns.
One of the markers has a gene called PHLPP1, which is commonly linked to the brain of people with the Neanderthal version. This gene controls myelin production for long-term communications for the brain.
The other marker is linked to a gene called UBR4; carriers have less active assets in a brain region. UBR4 helps to distribute neurons to the brain's brain.
These findings suggest that PHLPP1 and UBR4 develop to function differently in modern human brain. The modern human PHLPP1 can create an additional myelin in the cerebellum. And in our version UBR4 the neurons could grow faster in the bitch.
Simon Fisher, a co-author of the new Max Planck Institute of Psycholinguistics in the Netherlands, specified that humans were more sophisticated language tools. It can also be a more effective tool tool. Both require automatic and prompt delivery of mechanisms. And maybe it should not be coincidence that cerebellum and putamen are the key parts of our motor cycle, the same regions that have helped to change the general shape of the human brain.
For people with Neanderthal version of gene-shaped genes, there are limits to genetics, said John Anthony Capra, an evolutionary biologist at the Vanderbilt University who did not participate in the study.
Obviously, it is hard to predict the behavior of the genes, and even to explain some of the Neanderthal genes. The brain-based learning scientists will detect subtle signals at the noise level of the human genome. (Sputnik)
