Crab people, crab people. Taste like crab. Talk like people!

Those silly umans and their crabs...

@Longover1986 The story wasn't true, but I don't see what that has to do with the educational benefit in using it as an example of Artificial Selection. Greek Mythological figures didn't exist, but are used to explain things to laymen often, and that is precisely the purpose Sagan had for Cosmos. Teaching the masses in such a way as to make the content easier to understand.

What are Yoomans? And no I'm not a crab.

@Longover1986 It's not 'false', just wrong. At the time of filming this was accepted. Science is self correcting, hence why we now know it's not true. You don't have to be condescending when correcting with more up to date data, it's very unscientific, more emotive and, dare I say, egotistical.

@Longover1986 The fact that someone claims that this story isn't true doesn't make it not feasible. However, domestic cows, pigs, chickens, dogs, cats, goats, sheep etc. do exist and the selection process still goes on (of course not for people in cities who dont know shit about farming and breeding in the first place). And it works in the same way as described in the story. Let the ones with the properties you like replicate, and eat/kill all the others. Simple as that.

Do Umans eat Erbs?

@Bhikshu2 They also left a 7 year old boy in charge of their entire army!

Umans seem like interesting creatures, I'd like to meet one.

Sounds so obvious, yet so many still don't get it. Saddening really.

AS is a form of NS, however AS can be defined as any time humans get involved in the selection process, as opposed to just leaving species to adapt to their environment(NS). Breeding(intentional) is not the only kind of AS. Unintentional, as we see with these crabs, selection is still being made by humans, and thus AS.
And he's not on "crack"; he simply had a better grasp of the subject than you obviously do.
