Our Ancestors Infected Neanderthals With Diseases

Just read a horrific news today at New York Daily News.

"Researchers at Cambridge and Oxford Brookes universities analyzed ancient DNA and pathogen genomes from fossilized bones, and discovered that our Homo sapien ancestors carried these infectious tropical diseases when they began interacting — and sometimes mating — with our hominin cousins."

It seems herpes virus, tuberculosis, and tapeworm have been in existent long before agriculture takes place.
