Imagine you swallowed a small bird and suddenly gained the ability to fly … or you ate a cobra and were able to spit poisonous venom!

Adam Jacobson explains endosymbiosis, a type of symbiosis in which one symbiotic organism lives inside another.
Many animals, including humans, acquired essential ‘foreign’ genes from microorganisms co-habiting their environment in ancient times, according to new research. The study challenges conventional views that animal evolution relies solely on genes passed down through ancestral lines, suggesting that, at least in some lineages, the process is still ongoing.
