There simply IS no proof that is verifiable and true. I'm not saying similar types (take bats, for instance) did not section off to form the different groups of bats, but fossils are not proof of evolution, and scientists that believe in the theory are happy to use fossils as a way of showing 'proof'. (Of some sort. But it's not proof. What IS proof is that when one type of pig is crossbred with another type, it produces a pig. Back again to those intermediary forms where the genetics got lost, banished.)
As I keep telling you, PROOFS are mathematical statements, often expressed as EQUATIONS, as metrics, constants or variables. Proofs, mathematical equations are method of modeling the world or the physical phenomena, and these are found in hypothesis or theory as part of explanation or part of prediction.
The explanations, predictions and equations (proofs) are together, what needed to be tested. And the only ways to test these (explanations/predictions/equations) are through the OBSERVATIONS of physical EVIDENCE.
The “observations” should be able to provide information, like quantities, measurements, visual or audio recording of the phenomena (evidence), etc. These information from the observations of the evidence, are called DATA.
It is these EVIDENCE & DATA that verify or refute hypothesis or theory, not proofs (equations).
As I have said in my last reply to you, proofs don’t verify or refute anything, because proofs (eg equations, constants, etc) are parts of the explanations or parts of the predictions in a hypothesis or theory.
In biology, are the following evidence for evolution:
- Fossils are the physical evidence, not proofs.
- Genetic information, like RNA & DNA, are the physical evidence, not proofs.
- Comparisons of species and subspecies, like their physical traits, or the morphology of their built, forms or structures, these are all physical evidence, not proofs.
All the evidence obtained and collected since Darwin’s time, have verified the Natural Selection in the theory of Evolution. And since that time, the theory have been refined/modified/updated and expanded.
Evolution is even a more robust and more numerously tested theory than theory of gravity, theory of quantum mechanics or theory of electromagnetism.
