Why didn’t the asteroid that caused the extinction of the dinosaurs on Earth also lead to the extinction of all other living species?
In: Planetary Science
it killed almost all life but a very small percentage of life survived. And then over a very long period of time, because of evolution and mutation, that tiny percentage of life spread out and became the huge diversity of life that currently exists.
There is basically nothing that can kill ALL life, if even one single-celled organism survives, life will evolve again into a vast ecosystem, eventually.
