No, I wasn’t stoned. This thought was inspired by the post the other day about how trees evolved independently (e: multiple times) from different plants, the product of convergent evolution.

It’s almost a certainly that all current life on earth has the same common ancestors. And it makes sense very solidly for a lot of reasons.
For example all living organism have dna, and they all use the same 4 nucleic acids that their dna is made from. Neither of those facts are necessary requirements for life to exist, so since 100% of life does both of those things then that’s very strong evidence that 100% of life had a common ancestor.
