You may just have the Neanderthal DNA! Here are 6 traits to watch out

Throughout modern humans’ genetic makeup, approximately two percent of our DNA is inherited from Neanderthals.

The inherited DNA has shaped various traits and susceptibilities, as disclosed by experts. These genetic imprints, originating from an era of interbreeding between humans and Neanderthals, subtly impact present-day humans, underscoring an ancient mingling of genetics.

Specifically, a section of Neanderthal DNA notably increases the risk of nicotine addiction, despite the irony of Neanderthals predating the arrival of tobacco in Europe by millennia. Studies by Vanderbilt researchers suggest that while these DNA segments may have once conferred adaptive benefits to Neanderthals navigating new environments, they now contribute to adverse effects, including heightened vulnerability to nicotine addiction.

Also, certain Neanderthal DNA variants correlate with conditions like depression, psychiatric disorders, and neurological impacts, indicating a broader influence on human health.

Neanderthal ancestry manifests in various physical traits, including hair characteristics like thickness and straightness. Unluisler highlights studies linking Neanderthal lineage to thicker or straighter hair types, along with a higher prevalence of genetic variants associated with red hair—a trait observed in Neanderthals. Additionally, genetic links to circadian rhythm, affecting individuals’ waking habits and sleep patterns, are traced back to Neanderthals. Vanderbilt University researchers uncovered genetic markers in ancient Neanderthal genomes linked to early rising tendencies, possibly aiding adaptation to varying day lengths in different regions.

Features like nose shape, susceptibility to COVID-19 severity, tanning ability, and skin tone variations are also influenced by Neanderthal genetic heritage. University College London’s study suggests that certain nose shapes trace their origins to Neanderthal genetic material, potentially evolving as a response to colder climates. Studies during the pandemic indicated a chromosome region inherited from Neanderthals heightened susceptibility to severe COVID-19 symptoms, while genetics from Neanderthals also influence skin tones and UV light resistance.

In essence, the legacy of Neanderthal DNA continues to weave through modern human genetics, shaping a diverse array of physical attributes, susceptibilities, and health-related aspects, illuminating the intricate interplay between ancient interbreeding and present-day human existence.
