Genitals are the fastest-evolving organs in the animal kingdom. But why is this so? And what’s the point of having decorative private parts? Menno Schilthuizen explains how the evolutionary biology of nature's nether regions uncovers a hidden world of seduction, conflict, and rivalry.
Lesson by Menno Schilthuizen, animation by Mette Ilene Holmriis.

@nixl3518 2 года назад

If the info is correct, the animation is wrong. Corkscrew IN, corkscrew OUT. Also, how "cool" do you find being allowed IN, then she changes her mind??? Kind of nuts, I'd say, or would that be in keeping with being female? If we did that, there would be no human species.

The narration and animation in this are top-notch. It's fascinating to see the myriad variations of equipment various creatures use to procreate. One of my favorites in clever natural design is that of the lake drake, which not only has a relatively enormous tool for the job, but also bears a brush on said tool's end to whisk away a previous suitor's offering.

@Nawor1996 7 лет назад

so why is human genitalia so comparatively simple structurally?

@kayyumamcaoglu8671 7 лет назад

Rowan McMullan maybe because females select the best mate via socialisation so they don't need any needless actions to select their males

@42Fossy 7 лет назад

Rowan McMullan I'm guessing it's because we have a complex social system to distinguish good mates from bad, so theoretically, a bad mate will never end up in your bed in the first place? Obviously this isn't always the case, but we clearly don't go about sex the same way animals do.

@metholuscaedes6794 7 лет назад

Generational shifts are important, the more generations that can shift in a given time, the more things can happen, humans with comparativly long lifespans I gues simply dont mutate as oddly. *also the other given reasons as per above.

@festiverespecttrackingfanc6644 7 лет назад

I think it's because we don't mate much and in joung ages so it evolves much slower than the animals who reproduce quickly like insects. Maybe one day our genitalia will be something now unthinkable. Also we decide who to mate with.

@georgemargaris 7 лет назад

Rowan McMullan , human genitalia ARE the most complex when you also count the external abstractions of genitalia to it, like cars, clothes, wallets, etc to it
