I just couldn’t. From ScienceDaily (Mar. 9, 2011), we learn “Missing DNA Helps Make Us Human”:
Tracing the expression of the protein through development, Kingsley and his colleagues concluded that the sequence contributes to the development of sensory whiskers found on the faces of many mammals, and prickly surface spines found on the penises of mice and many non-human primates. Previous studies show that complete inactivation of the androgen receptor gene lead to defects in whiskers and failure to form penile spines. Although humans still retain the androgen receptor gene, the loss of regulatory information for expression in whiskers and spines could help explain two human-specific anatomical traits: absence of sensory whiskers and lack of spines on human penises. Loss of penile spines is one of several traits thought to be related to evolution of pair-bonding and monogamy in the human lineage.
Yes, one can see the logic of the sentence greened above.
Imagine. A thesis of human evolution that I can readily believe, amid wastelands of nonsense.
