For both male and female bonobos, that free love philosophy
makes evolutionary sense. The males get to spread their seed and the females get to take in the seed
of multiple males, which then compete against each other
to fertilize her egg. It's survival of the fittest, for sperm. There are aspects of bonobo anatomy
that seem adapted to promiscuity, and intriguingly, you can also find
a lot of them in humans, suggesting we may have evolved
to be non-monogamous, too. There's body dimorphism. In species that are more promiscuous, the males tend to be 15 to 25 percent
larger than the females

For both male and female bonobos,
00:00:04.087 --> 00:00:07.298
that free love philosophy
makes evolutionary sense.
00:00:07.382 --> 00:00:09.634
The males get to spread their seed
00:00:09.717 --> 00:00:13.012
and the females get to take in the seed
of multiple males,
00:00:13.096 --> 00:00:15.089
which then compete against each other
to fertilize her egg.
00:00:15.973 --> 00:00:18.976
It's survival of the fittest, for sperm.
00:00:19.999 --> 00:00:23.648
There are aspects of bonobo anatomy
that seem adapted to promiscuity,
00:00:23.731 --> 00:00:27.652
and intriguingly, you can also find
a lot of them in humans,
00:00:27.735 --> 00:00:31.322
suggesting we may have evolved
to be non-monogamous, too.
00:00:31.406 --> 00:00:33.449
There's body dimorphism.
00:00:33.533 --> 00:00:36.244
In species that are more promiscuous,
00:00:36.327 --> 00:00:40.373
the males tend to be 15 to 25 percent
larger than the females.
