Social behavior

I'd like to dedicate this episode to Dr. Hans Kruk, who served as the Deputy Director of the Serengeti Research Institute in Tanzania on the UK Natural Environment Research Council and on the Institute of Terrestrial Ecology in Scotland.

He has written seven books, including The Spotted Hyena, Predation and Social Behavior, The Social Badger, Wild Otters, and The Call of the Carnivores, Travels of a Field Biologist.

Dr. Crook has shed a lot of light on hyena behavior, and much of what we know about them is because of his work.

This concludes our episode.

He's full professor in the School of Sciences at Santo Tomás University in Chile.

And today we're going to talk about, uh, levels of selection in the context of evolutionary biology, um, and multilevel selection and its implications in terms of multicellularity, social behavior, cooperation, cultural evolution, and other related phenomena.

So Dr. Marín, welcome to the show.

It's a huge pleasure to everyone.

Now we also know that other thing called indiretic, indiretic, in ...

Sorry, indirect genetic effects, which means how the other genes of, or neighbors, or neighbor individuals affect my gene, uh, a specific gene of a focal individual, and in consequence, uh, that, uh, effect of the gene on the fitness of, of a focal individual.

We know also now that indirect genetic effects, for example, in things like social behavior in animals, is really, really common.

So what I'm saying with all of this is that now the empirical data that we n- well, that we have, particularly over the last two years, kind of makes us realize that, uh, that Wright, Sewall Wright, uh, was, was correct, uh, in his model of, of natural selection and, and evolution.
