In conclusion, clear evidence exists that year-round reproductive cycles, plus the requirement that human sperm must be kept close to a constant temperature of 4˚C below that of the core body temperature, effectively explains the existing design of testicles. Men who have uncorrected non-descended testicles are usually infertile and prone to many other health problems, including cancer. In short, the existing complex design is required for many reasons, including fertility and health reasons. It is, therefore, clear that Hafer’s poor design claim, along with those of other evolutionists, is grossly irresponsible.
Yes, their arguments are dumb, but that’s not their biggest problem. The problem is they’re arguing theology not biology.
