A group of researchers decided that people with a longer-known brain and skull, which are similar to a priority, a direct descendence of Neanderthals, according to a study published today in the scientific journal Current Biologoy.
The researchers carried out a series of seven skull computing tomography of Neanderthals, plus 19 new human skulls, which allowed them to analyze the inside of those skulls and their accuracy accuracy. In the same way, scientists They analyzed around 4,500 people they had two genetic data and images of magnetic revival (MRI) of their tools.
"We thought we can recognize specific parts of Neanderthal DNA in a large enough sample of people, we can test if any of these are going to a hard-brained brain attack ", which explains Simon Fisher, a neurogenetist at the Max Plack Psycholinguistics Institute in Nimeja (Netherlands) to Live Science. "[Esto] it allows us to focus on the genes that may be important for this device, "to continue with the Dutch country scientist.
Despite this, a fisherman has a & # 39; stressed that Changes to small Neanderthal gene changes, so – it's to make sure – one can not see if someone is in a position; coming from the Neanderthal just by looking at someone's shape.
According to this new study, two genes previously studied in other brain development investigations, related to the generation of neurons and others related to the development of salted fusion around the strange cells.
The researchers also found that this Neandertal DNA has a stronger impact on brain structures called putamen and cerebellum, both essential for preparation, learning and coordination of movement, as well as memory, attention, speech or language , among other human activities.
The science indicated that if there is more Neanderthal DNA than one than the average, that does not mean that the brain is worse. "Two people with a degree of Neandertal DNA, for example 1% of the genomes, can be completely different pieces," Fisher definition. On the same lines, experts show that they are cranial differences They may not have been seen in the time a baby was born – who has a skull like Neanderthal – but they are related to the growth of brain himself
Fisher determines that future research can be improved by doing so. using more Neandertal DNA tied to a new human bracket, to determine the specific effects of these genetic changes when developing a brain device with DNA from our ancestors in the work -lann.
