The accumulation of mutations that achieve fictation, do.
Mutations do not achieve fication.
Speciation: a gradual process that unfolds in populations, not in individuals and not overnight.
The inability to reproduce does not make a new species.
lol....
That's a piece of data. An observation.
When we say that there is no proof in science, we are talking about explanations.
You can't prove explanations in science. You can only support them with evidence or falsify them.
So there is no "proof". Only evidence and disproof.
That is piece of data that can and has been proved scientifically.
That is pure nonsense invented by those who finally realized they can't prove anything in the TOE.
Proof is not about explanations. Proof is about seeing and repeating something.
Perhaps you heared the phrase once: "science isn't in the business of proving things. it is rather in the business of disproving things..."
That isn't the dumbest thing one can say about science, but it is in the top 5. Make that the top 3.
All of them, just data/measurements/observations.
Data, measurements and observation proved by real science. Too bad science can't prove any theology the TOE preaches
