"The Enduring Impact of an Ice Age Discovery on Humanity"

Researchers have linked a gene inherited from ancient Denisovans to neurological disorders in modern humans, suggesting that it may have helped ancient humans adapt to colder climates. The gene variant SLC30A9, responsible for controlling zinc transportation across cell membranes, has been found to be associated with conditions such as depression, hyperactivity disorder, autism spectrum disorder, and schizophrenia. This gene variant, believed to have originated from interbreeding with Denisovans, has spread to majority of modern populations outside Africa, impacting their susceptibility to neuropsychiatric disorders. The discovery offers insight into the influence of Denisovan DNA on modern humans and sheds light on the genetic adaptations to different environments.

"Genetic Expert Validates Single Ancestor Theory for All Blue-Eyed Individuals"

An expert has confirmed the theory that all blue-eyed people are descendants of one person who lived near the Black Sea 6,000-10,000 years ago, with a mutation in the OCA2 gene causing brown eyes to turn blue. This single recessive gene is responsible for blue eyes, and all blue-eyed individuals are distantly related to the original founder. However, it's not the only gene that contributes to eye color, as there are about eight genes involved in determining eye color in humans.

"Unveiling 6 Bizarre Traits Indicating Neanderthal DNA Presence"

Genetic engineer Sebnem Unluisler suggests that certain traits such as nicotine dependency, hair type, sleep patterns, nose size, Covid-19 reaction, and tanning difficulties may indicate the presence of Neanderthal DNA in modern humans, as a result of interbreeding between Homo sapiens and Neanderthals. These traits provide insight into the genetic legacy of our ancient human relatives and their influence on various aspects of our physiology and health.

"Uncovering Neanderthal Legacy: 6 Surprising Traits Linked to Modern Humans"

Research shows that many humans have Neanderthal DNA, with European or Asian backgrounds having 1% to 4% due to interbreeding, while some African populations have almost none. Genetic traits linked to Neanderthal DNA include a higher risk of nicotine addiction, straight and thick hair, being an early riser, a taller nose, susceptibility to severe COVID-19, and tendencies towards lighter or darker skin tones. These traits are remnants of Neanderthal influence on modern humans, despite their extinction 40,000 years ago.
