Evolution isn't something with "progress". It's just imperfect replication culled by natural selection(and by "natural selection" I mean "literally any reason why an organism does or does not breed before it dies")
Like, early light sensitive patches of skin weren't DNA going "Okay this is the first step in achieving the eye, it sucks but it's the best we can do for now", it's just that the critters with them managed to breed more than those without, and the same thing kept happening for the offspring with more and more sensitive and capable patches, on and on until we got where we are.
Yup, people tend to ascribe intention to evolution but it's just a process as natural as rain. Water doesn't want to go anywhere, it just does. Genes don't want to mutate, they just do. And if a mutation makes species more likely to survive, sometimes it does, and the gene spreads. No goals, no reason, no plan. Just something that happens.
And beyond that, beneficial mutations don't even guarantee the gene survives. It still has to breed, and even it does, there's STILL no guarantee that said mutation/deviation will happen in the offspring.

Good for Brian, they deserves it.

It's true. I started out as Brian, now I'm Kerry Ann.
This isn't even my final form!
