No? Why not? Why DON'T you think that fish could again "evolve" to become apes?
Because they are on different evolutionary branches.
Species don't evolve twice. And in this case, it's not just species. It's entire evolutionary branches (tetrapods, mammals, primates,...)
It's not going to happen.
Or perhaps apes to devolve, no, I mean, evolve, to be fish.
We have examples of mammals that evolved into sea animals. They are called dolphins and whales and stuff.
They might look like fish, but they aren't fish. They are mammals.
What's the "scientific" answer to those questions?
That species can't outgrow their ancestry. Species don't jump branches. Speciation is a vertical process, not a horizontal one.
Cats will not evolve into dogs.
Maybe apes need to go back to water breathing organisms. C'mon -- if spaceships could have deposited the start of living matter on the earth, propose some scientists, why not a nice little thought about apes evolving to fish? WHY NOT?
Because it doesn't work that way. I'm sorry that you insist on this willful ignorance, but I don't know what to tell you.....
This once again ties into the mistake you have been refusing to correct for at least the past 3 years. You categorically refuse to understand / learn that speciation is a
vertical process. Species produce more of their own or SUBspecies. Visualized on the tree of life, they branch out into sub-branches.
They don't jump branches.
