Neanderthal Interbreeding: How Does It Tie In To Our Modern-Day Traits?

Neanderthal Interbreeding: How Does It Tie In To Our Modern-Day Traits?

New research suggests that Neanderthal interbreeding could be the reason why modern humans are more susceptible to certain health issues, or developing certain traits or characteristics.

A study from the Max Planck Institute of Evolutionary Anthropology published Thursday in the journal Science suggests that for most people, about 1.8 to 2.6 percent of modern human DNA was inherited from our Neanderthal ancestors, with the percentage especially high among people of East Asian descent, and lower in those of western Eurasian descent. This was based on in-depth DNA sequencing conducted on a Neanderthal woman who existed about 52,000 years ago in the caves of Vindija, Croatia.

According to the Los Angeles Times, this marked the second time that scientists were able to conduct genetic reconstruction so detailed that comparisons to modern humans were possible. The first analysis, which was based on an individual who existed about 122,000 years ago in the Siberian province of Altai, suggested that Neanderthal genes took up a 1.5 to 2.1 percent share of modern human genes.
