Neither does the progression from one species to another need the actual computations, only the evidence that one led to another.
Nontechnical articles that explain the process of a system to a nontechnical person abound and do a very good job. Hiding in technicalese has always been a method of covering up shoddy science.
A lot of highly technical people in sciences such as biology and other relevant sciences are totally against the notion of intra-species evolution, and they can read and understand the technicalese, and see its flaws. Not only see its flaws, but point them out to a layman so he can understand them.
Natural selection. The process of natural selection is claimed to have started by blind chance. Read you own evolution gurus. If it did not start by blind chance, it being a organized stricture that governs an orderly process, then it must have been created by some intelligent source. If the latter, your premise fails.
Let me say again, both evolution and creation, as these concepts are taught, fail equally. I don't subscribe to either one.
