I guess at some point a species decided to make love, not war, and and behold – male and female sexes!
Imagine you have to fight with your wife each time you wish to inseminate her! Should she be the winner, SHE will inseminate YOU with one of her two big penises! That is equality!
Some sort of trade descriptions act (UK only?) ought to apply to the naming of things. Those worms aren’t flat. They’re all frilly and ripply. :-D
It probably happens a lot. The synapsid name turned out to be wrong. The Big Bang naming was deliberate sabotage though.
I noticed this a while back and it’s really cool. I think that flatworms have the right idea myself, just have a quick tussel and the loser ends up with the babies. The perfect reproductive system and really gives meaning to the term ‘penetration’.
You know you’ve been reading too much of Pharyngula when you misread the category as ‘orgasms’ and don’t even double-take.
You know you’ve been reading too much of Pharyngula when … you get an erection watching worms.
You know you’ve been reading too much of Pharyngula when … you wonder if male flat worms get Y chromosomes and in general, how worms manage their sex chromosomes?
You know you’ve been reading too much of Pharyngula when … the word sex makes you think of worms, jellyfish, skid.
