You've been told this many this many times before, I feel sure, but as the others have had enough of your bad faith "questions" I will answer, at least for the benefit of any other readers who may not know. Evolution makes testable predictions in a variety of areas.How is human evolution a testable concept? You say in general it's a testable concept. Please detail that with tests that have been performed, thank you.
Perhaps the most obvious is what types of fossil we should find in rocks of a given age and what changes we should be able to track through the fossil record at different ages. This is done all the time. We have a huge range of fossils which show forms intermediate between earlier ones and later ones, just as evolution predicts.
Secondly, evolution predicts that DNA similarities should be more marked between species that are shown as being closely related in the evolutionary tree than those that are more distantly related. This, again, is what we find in practice. Furthermore, the fact we share 50% of our DNA with a banana points towards a common ancestor for both plants and animals.
Thirdly, evolution predicts that organisms adapt to their environment via natural selection. We see this occurring in real time, among those simple organisms that have a very fast rate of reproduction, when they are put into a hostile envirnoment, Famous examples are bacteria, viruses and cancer cells. We have just lived through a pandemic in which evolution has been observed several times over, in the development of different strains of virus that are more capable of evading the immune respone triggered by our vaccines.
So the fact of evolution is as plain as the nose on your face, while the theory of it, while still being further developed as more mechanisms are uncovered, is borne out by huge amounts of evidence.
