In the past few months alone, researchers have linked Neanderthal DNA to a serious hand disease, the shape of people's noses and various other human traits. Research shows some African populations have almost no Neanderthal DNA, while those from European or Asian backgrounds have 1% to 2%. For example, Neanderthal DNA has been linked to auto-immune diseases like Graves’ disease and rheumatoid arthritis. The list goes on: Research has linked Neanderthal genetic variants to skin and hair color, behavioral traits, skull shape and Type 2 diabetes. Researchers found the skulls of domesticated dogs in Homo sapiens sites much further back in time than anyone had found before.

☆ New studies shed light on how genes might shape a person’s experience with Covid-19

New research is exploring another dimension to the puzzle of how people experience this infection: genes. Hollenbach says it’s the job of HLA molecules to present pieces of proteins to the immune system so they can be recognized if they’re ever encountered again. The researchers then took a closer look at this group to see if there were any similarities in the genes that coded for their HLA molecules, and there were. So folks with these HLA molecules likely already had some preexisting immunity against SARS-CoV2 and were able to clear the virus before it caused symptoms, Hollenbach said. Genes, Zeberg said, are likely only one part of reason why someone develops long Covid, and there are probably a slew of genes involved.

☆ How interbreeding between humans and our Neanderthal cousins 40,000 years ago affects our health today

Interbreeding with Homo sapiens helps to explain why millions can't straighten their fingers. There is also a Neanderthal gene variant that increases the risk of somebody dying from COVID-19. The study evidences that "intermingling" from Neanderthals and our Homo sapiens ancestors is consequential in examining the prevalence of certain diseases, researchers said. No more than 7% of the human genome is unique to Homo sapiens, according to a study published in the journal Science Advances. Brain development and function are what sets Homo sapiens apart, experts explained.
