Would you raise the bird that murdered your children? - Steve Rothstein

[@thenerdbeast7375]

You forgot to mention one important aspect of brood parasitism: retaliation. Some species of brood parasites like some cuckoos have an almost mafia-like control over their hosts. The mother keeps an eye on their egg/young from afar and if the hosts reject the egg or chick, the parasitic species will destroy the nest and prevent the host from breeding further that season out of spite. So for some hosts it is in their best interests to foster the parasitic chick in the hopes that their next brood won't be parasitized rather than reject the foreign egg and/or chick and be unable to breed at all. "That is a nice nest you have there, it would be a shame if something...happened to it."

Wait so the cuckoos are racketeering child care? That's actually incredible. If that goes far enough, they might evolve into a full fledged government haha. One evolves to oversee and one evolves to escape oversight.

[@drsharkboy6568]

@@eggapramuditya because evolution is blind. Why do you think cancer, down syndrome, diabetes, etc. happens? It’s because there are many hiccups that happen when creating a non-identical offspring. The only reason we don’t see all these health problems in other animals as often is because natural selection easily weeds them out. We prevent that process from happening for our species as often, allowing the genes that allow those problems to keep persisting when they naturally wouldn’t. Everything that happens evolutionarily is a 1 in 100 billion accident. Why do you think it took 3.5 billion years for life to go from bacteria to humans? There is no intelligent design, there is accidental design that just works. All it could have taken was one alteration in either our ancestors or the environment millions of years ago and we could have ended up with Cenozoic dinosaurs or a planet of bugs that got to evolve out of their physical limitations because vertebrates never became a thing. That’s why everything in evolution is an accident.

I thought this video was going to explore the existential question of if I (as a human) would raise a bird who murdered my (also human) children and I was not ready to wrap my head around that scenario.

[@D_U_N_E]

Just as a notation, an evolutionary arms race is not intentional. It's an accidental process in which parasitic eggs with certain traits are kept over parasitic eggs without these traits. Over time this can lead to an evolutionary shift in the eggs/parents. Such as placing only in specific nests, having different physical properties, etc. Too many things make this seem intentional, it tends not to be - and the parasite if unable to have these adjustments can also go extinct. Picky birds are also accidental, and have similar properties.

[@erlkinglook4824]

What is intentional, and what is not? Sure, 'evolving' a feature of parasite identification is not intentional (no evolutionary process ever is), but a chick killing its fellow nestlings or a parent killing an imposter chick can be framed as intentional, as far as you can assign intentionality to individual animals. Talking about intention in animal behaviour is always tricky, but since humans are agent-centric conceptualisers, your script might sound rather stilted if you (intentionally) take out all the intentional language from it.

[@catdogmousecheese]

Dude, you know "evolutionary arms race" is just an analogy, right? Birds aren't literally plotting against each other like Russia and the US during the Cold War.

[@D_U_N_E]

I mention this as I see a lot of people take the analogy as a way in which evolution works. I've heard multiple people question why animals don't just evolve a feature to survive.

[@Ardeleus]

Nothing is intentional per say, but evolution is effective, at least enough that the species still survive to this day. If an evolutionary feature benefits a species in a specific environment, that mutation will survive and occur/last again and again. Just because it was randomly stumbled upon does NOT mean it was randomly successful. This means if you restarted life, it would still end up very similar if not the same as we have today. This is because altho the mutations for evolution is random, the mutations that stay are not random. A creature with a mutation to have thick fur to keep warm in the cold would not survive in the desert, and a creature with legs would survive on land better than a creature with fins on land. If evolution got "unlucky" it would simply take a bit longer before the same features would pop up again because they are successful in that specific environment and condition, even if it was obtained randomly, it would not keep existing if it was truly random and had no merits behind it, and if it did have merits behind it then it would've appeared no matter what, even if it is evolved randomly. So no, evolution is not random.

[@salemsaberhagan]

​@@D_U_N_E the response to the question "why don't they evolve a response to survive" is simple: they haven't found a response that works well enough yet. Intentionality has nothing to do with it. I dare say you won't deny intentionality in human behaviour & have we yet evolved an appropriate species-level response to human induced climate change? We have not.

There is a very powerful parenting instinct in most animals, which stands to reason since the production of babies takes a lot of energy; you wouldn't want to waste that whole investment by not putting in the effort to raise them to adulthood. That's why the parasitic chicks aren't rejected, and it's the same reason a dog or cat will raise a litter not its own if it loses its own litter. Horses will also adopt youngsters, but it's trickier; they have to be the same age as the lost foal and ideally the same gender.

It's both fascinating and horrifying to think how morals vary among different animals, and among different human cultures. For example, in ancient China, the "marriage alliance" was an appeasement strategy whereby chinese emperors had to marry princesses (not always their daughters) to rulers of enemy states - usually tribal nomadic people - in exchange for temporal peace with these states. It was a controversial policy, but it saved lives.

[@voidishprattles4319]

Arraigned marriages to ensure peace are extremely common amongst nearly all human societies. Their was also a practice of giving your children to a rival to ensure peace as if you broke the treaty then your child would be killed. It's human nature to have an "ends justify the means" mindset. I can recall this amongst European aristocracy as well as Japanese ones and it's a large part as to why women were treated as objects for so long because for these nobel families... They were just objects, things to trade in order to ensure power.

This is a very interesting question. Brood parasitism occurs in several bird groups, but most birds do not exhibit this behavior. This means that either, (1) brood parasitism existed in the dinosaur ancestor of birds and was subsequently lost by most bird species, or (2) the behavior evolved independently in several bird lineages. The second possibility is much more likely. However, if brood parasitism evolved numerous times in birds I don't see why the same couldn't happen in dinosaurs. As other commentators have pointed out, to test this hypothesis you would probably have to find a lot of dinosaur nests with eggs. How exciting would if be, though, if a dinosaur nest was found with eggs from two species!
