Scientists May Have Found a Key Shift Between The Brains of Humans And Neanderthals

The modern human brain takes more time to develop than the Neanderthal's, according to scientists experimenting on mice.

Slow and steady is the winner here. The extra time is caused by differences in the genes that make up the human body.

According to the results of the study, the wrinkled outer layer of our neocortex plays a role in protecting us from disease, a feature Neanderthals don't have.

In recent years, scientists have been able to sequence the Neanderthal genome from ancient remains, revealing details about how it compares to our own.

The branch that gave rise to Neanderthals and the Denisovans changed when modern humans deviated from it.

It was not clear what functions the substitution of anhydra had on humans and Neanderthals.

The distribution of chromosomes during cell division is a function of six of the identified replacements. Felipe Mora-Bermdez is a geneticist at the Max Planck Institute of Molecular Cell Biology and Genetics in Germany.

The natural subject was laboratory mice, which are similar to Neanderthals and apes in their structure. The researchers took the amino acids from modern humans and replaced them with them.

The research was taken in different directions. They created organoids of human brains from stem cells that were not alive or sentient, and replaced them with the Neanderthal/mouse/ape variant.

The results were very interesting.

When the chromosomes are distributed to the daughter cells of the neural, there are fewer errors because of the longer metaphase.

The Neanderthalized human organoids had more chromosome separation errors than the control organoids. Neanderthals had more errors in their chromosomes than modern humans.

The results show that the change was to the benefit of modern humans, since errors in the number of chromosomes can lead to serious disorders and cancer. Neanderthals may have had a higher incidence of chromosomal disorders than modern humans.

The researchers wrote in their paper that the probability of chromosomal mis-segregation in modern humans may be lower than in Neanderthals, Denisovans, and apes.

There is more work that needs to be done to address the importance of these effects.

The research has appeared in a journal.
