Because people here talk a lot about extinction, I just wanted to point out that 99% of all species ever to have lived died out. What remained are the one we currently are in company with.
Also, after each mass extinction, there was a massive radiation of new species, for example the Cambrian explosion. No new species without extinction. Evolution, baby!!!
- wruza 4y agoCambrian explosion is probably not a good example because one of the reasons (correlations) was oxygen levels and other planetary chemistry shifts. I mean yes, rocking the boat should probably restructure life in a more sophisticated way (like shaking a cup of screws makes it fill more gaps and settle better), but if the previous bacteria went extinct without these changes, that explosion could be unremarkable.
- nathias 4y agoI just want to add that 100% of all species will eventually die out. Cosmic death, baby.
