When it comes to animal life on Earth, humans like to think of themselves as the best, but it’s not, according tomedia reports. Many of the ancient ancestors of man were mixed with Neanderthals, and this “mixed” trace is still present in human DNA today. It was discovered about a decade ago that many people had Neanderthal genetic code in their bodies, and now a new study is helping to pin into the effects of this DNA on the human body.
It is understood that researchers are looking for Neanderthal DNA by cultivating human brain tissue. It turns out that traces of early human interactionwith with Neanderthals have been waiting to be discovered.
The study was conducted by Max Planck’s Institute for Evolutionary Change and J. Gray Camp leads the use of stem cells from the European biobank Human Origin Pluripotent Stem Cells Initiative ( HipSci ) . Most of the individuals who submitted genetic material to the project came from the UK and northern Europe, where scientists already knew there were high density humans and retained traces of Neanderthals’ past.
By using stem cell materials, the researchers built small pieces of brain tissue called organ-like tissue. The group originally belonged to humans, but it still contained up to 4% of Neanderthal DNA. This may not seem like much, but when the small portion of each individual is combined, a larger proportion of Neanderthal genes is eventually obtained.
Brain fragments are cultured in petri dishes, but the DNA they carry may have an impact on the real world in the future. Understanding how Neanderthal DNA affected human evolution will explain the origins of things like hair and skin tone, as well as give us a better understanding of how Neanderthals lived. In addition, the use of Neanderthal DNA to build organisms can reveal cognitive abilities about health, diet and even ancient humans.
