Our Ancestor Homo Erectus Is 200,000 Years Older Than Previously Thought

14. There are several online articles

about the effects of Neanderthal and Denisovan DNA in modern humans and how their DNA affects us today. They all include references to the immune system and allergies, but you have to scroll through them to find the allergies reference. DNA from those two human relatives also affects things like blood clotting and strokes, fat metabolism, autoimmune disorders, a specific type of precancerous skin lesions (actinic keratosis), in addition to allergies.

Once beneficial according to life styles in the past, those genes are less so in the modern world environment. Besides having multiple allergies, I have also had an actinic keratosis skin lesion removed from my arm.

The articles that I found have pretty long URLs. You can find any of the articles easily by doing a search with the words "Neanderthals and allergies." Sources include Science Magazine, NPR, and Smithsonian Magazine among many others.
