The Viruses That Shaped Humanity

The video explores the surprising role of viruses, particularly retroviruses, in human evolution and development. While often associated with illness, some viruses have contributed positively to our genetic makeup. Retroviruses, which integrate their genetic material into host genomes, have influenced human development, immunity, and even certain diseases. Human endogenous retroviruses (HERVs) make up a significant portion of our DNA, affecting embryonic development and adult immunity. The video also highlights ongoing research into the potential links between HERVs and diseases like multiple sclerosis and ALS.
