As far as I know there's no evidence that loss of spines is adaptive so it's just as likely that it's an accident.<br /><br />Imagine that we could go back in time two million years. At that time all of our ancestors had the spines. A mutation arose in one male individual leading to loss of spines. According to the just-so story, that individual gained a selective advantage over the other dozen-or-so males in his troop leading to the eventual exclusion of all spine-bearing grandchildren and great-grandchildren from mating with the dozen-or-so females of reproductive age. <br /><br />One wonders how the young women became so adept at selecting the spineless males over the ones with no spines. Or was it truly the case that the absence of penis spines caused the mutant males to invest a lot more time in raising their children? <br /><br>Larry Moranhttps://www.blogger.com/profile/05756598746605455848noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-32289082115742336312011-03-18T01:57:02.971-04:002011-03-18T01:57:02.971-04:00Knowing what a dirty word "adaptation" c...Knowing what a dirty word "adaptation" can be with you, do you think the loss of penis spines is an adaptation or do you feel the authors conclusions are a "just-so" story.<br />I admit this question borders on snarky, but it is also sincere.MJhttps://www.blogger.com/profile/00033310680352043403noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-55380359913630192222011-03-16T10:23:06.940-04:002011-03-16T10:23:06.940-04:00With all the "science" in the world, sci...With all the "science" in the world, science important to the wellbing of the inhabitants of this planet, don't you think time might be better used? Excuse my offense, and with "pubescent male humor" aside, but might I suggest this topic rather innane? Furthermore, it is the view of this disturbed individual, that interest in this subject, is indicative of the same veins of thought, with comments varying only because of modesty, or etiquette. Are we in danger somehow from an imiment "reactivation" of the "penile spine" gene?
