It’s always been about animals, for the reason that I’m a biologist as a result of and thru. To be able to pull what I do off, you need a strong background in evolution, behavioral ecology, social biology and even more. But This can be storytelling also.

They're able to no longer assume social monogamy establishes how genes are distributed inside of a species. The lessen the fees of genetic monogamy among the socially monogamous pairs, the less of a role social monogamy performs in figuring out how genes are distributed among offspring.
