I neglected to include another bit of foolishness from that ridiculous Pivar paper. This is a perfect example of “looks like” biology, which is all the paper is: drawing correspondences by saying X looks like Y, based on superficial morphological similarities, and worse, then announcing that because X looks like Y, you have therefore explained both X and Y.
Behold, Figure 20!
Eyeballs and testicles, they’re both paired spheres dangling from stalks, am I right? Therefore, just pointing that rough similarity out simultaneously shows that they are produced by the same process, and explains how they developed and evolved. Done! Gimme my Nobel prize!
