RE: Tree of Life: How Animals Became Animals?
I think that Choanoflagellates did adopt multicellular abilities from further back in the tree before animals, it is more likely that it happened that way. Well, that is what I think. But it would be extremely interesting if they and animals would develop those abilities separately. How would that be possible? What do the scientists say? What do they think is more likely? Do you know maybe? 😌
Well, convergent evolution as it's called, is surprisingly common. The idea that the same thing evolved completely separately multiple times. For example, wings. Bats, birds, insects, even fish - all evolved wings separately as the solution to whatever challenge they had.
Eyes evolved several times too, camouflage and mimicry, flipper fins in dolphins (mammals) and sharks (fish) - which is why sharks are vertical and dolphins are horizontal.
It's possible that the need for a brainy nervous system was needed but the animal kingdom took over that environment faster... so I think it's possible!
Of course, convergent evolution. Well, then it is possible. I wasn't looking at the big picture here. Thanks for the answer. I look forward to your new posts, they are really interesting.
