OK, so what is the problem? Yes, biologists accept that 3 billion years ago there were only bacteria, the eucaryotic cells developed about 2 billion years ago, that multicellular life developed about 800 million years ago, etc.
Now, does every biologist remember all of this? Certainly not. But neither does every physicist remember ever formula in specialties not their own. That doesn't change the acceptance of them.
So what, exactly, is your question? is there doubt that we have bacteria->eucaryotes->multicellular->vertebrates->jawed fish->amphibians->reptiles->mammals->humans?
Nope. That basic outline is solid. As always, details take more time to fill in, but many of those details have, in fact, been filled in.
"That basic outline is solid. As always, details take more time to fill in, but many of those details have, in fact, been filled in" that is what I was asking to a certain point and I agree.
Next; do clergy and religious people accept it as solid? Or do they partially accept it and partially reject it because they believe a god was involved?
I may have over stepped into your reply when you said everyone. I took it as it also included religious people in your everyone.
