science tells us that humans exist almost certainly because of the decimation of the dinosaurs and the majority of lifeforms on earth at that time. my understanding is this is not the first time life has been wiped out and new life forms evolved in their place. lifeforms that may not have arisen without the destruction of the others. i am told that there is evidence that there was a snowball earth where all lifeforms except perhaps bacteria was destroyed and life had to begin again at that point. my questions is...i wonder if anyone has ever speculated what life would look like had evolution never been interrupted?
