You are mixing up proving the theory of evolution and using the theory to make speculations about the past. The speculations are only taken as seriously as the evidence they are based on. The last time you made a blog post you complained about the evolutionary psychology behind a loud female orgasm. I had to look it up for you that it is seen in other apes TODAY and since other things prove (with statistical accuracy) that we have a common descent with other apes, these speculations are viable.
Where is this supposed proof or strong evidence for the speculations? "Viable speculation" is not the standard in science for believing things to be true, and using them as a basis for conclusions.
