Immortality in Nature Explained

⌛ Today I'm talking about the four types of immortality found in organisms across the tree of life, and how these examples can help us understand treatments in human longevity. If animals can evolve to do it, can we engineer ourselves to do it too? Perhaps only time will tell.

Keywords: Immortality, Immortal Jellyfish, Lobsters, Nature, Planaria, Clonal Colony, Bryan Johnson, Hydra, Pando, Tardigrades

WHO AM I?
Hey, I’m Dan. I double majored in biology and psychology and like to make videos about evolution and behaviour and stuff. I have a lot of thoughts and need creative outlets at all times, so making these videos is a great way to cope with the struggle of indefinite existence. I plan to stick around on YouTube for a while, so I hope to see you around for years to come :)
