It’s not through study of evolution. It’s through study of the animals and humans themselves and drawing conclusions that they fit. You can reject various aspects of evolution, such as “common descent” and still accept that pigs are similar to people and their tissues are interchangeable to a degree. You can be a YEC and a Creationist of the literal Genesis variety and still do useful scientific research and applied work in the fields of medicine, genetics, molecular biology, biochemistry etc.DNA changes in the pathogens themselves IS evolution.
And it is precisely due to studying evolution that we discovered that humans and pigs were similar enough to use pig valves. It did have a lot to do with physiology and anatomy, but genetic similarities are also necessary. Too different and the body rejects it. Hence the study of the human body and pigs in the context of evolution was quite crucial.
Note that, as said before, many people who deny evolution, don’t deny all aspects of it. Behe does not deny all aspects of it.
Faulty logic u have.
