Here’s what would have given modern humans an edge over Neanderthals, according to the study

Studies in the past have shown this: Neanderthal brains were the same as those of modern humans. Conversely, scientists know very little about the early development of the brain, because the soft tissues that made them do not keep well in the fossils found. But a study released on Sept. 8 could say more about what would give modern humans an edge, CNN reports.

An ability to produce more neurons?

According to this study conducted by the Max Planck Institute in Dresden, Germany, which specializes in molecular and genetic cell biology, a genetic mutation would have triggered the creation of neurons more quickly in the brain of Homo sapiens. An amino acid would be the element that differs between the human and the Neanderthal variant. “We have detected a gene that helps make us human“revealed the study’s author and professor emeritus of the institute, Wieland Huttner. The scientists performed analyzes on mice and found that inserting the gene in question increased the proportion of specific cells that create neurons in the neocortex region of the brain.

This ability to produce more neurons has likely given Homo sapiens a cognitive advantage regardless of brain size. “This shows that although we don’t know how many neurons the Neanderthal brain was made of, we can assume that modern humans have more neurons in the frontal lobe of the brain,” said Wieland Huttner. Scientists wondered if Neanderthals’ frontal lobe was as large as humans, but ultimately the question was raised, as modern humans have more neurons in their frontal lobe.

“Dramatic Differences” on a Cell Line

Professor at the University of California, San Diego, and director of the stem cell program and center of archeology, Alysson Muotri, explains that “quite dramatic” differences were noted during animal tests, but they were more subtle in the organoids. He also points out that it would be useful to do this experiment in another cell line, which is why, according to him, it is “premature to notice differences between Neanderthals and modern humans.”
