Cockatoos in Sidney, Australia are teaching each other how to open trash bins. The techniques are spreading through social learning as the birds develop different cultures in different areas.


What fascinates me as a xenobiologist is that it's not a single-point phenomenon. There are multiple cockatoo super-genii in Sidney who are independently inventing the big-box dinner. Any species can throw one super-genius. Homo ergaster is kind of infamous for having done that ... and then everyone copied that sophisticated hand ax for over a million years, rather than expanding the repertoire with more tools. What marks the potential for advancement is the repetition of genii and the ability of those around them to copy and modify their inventions.

This is the second species I've seen doing this. The first is the Japanese macaque or snow monkey. Imo famously invented the sand-free sweet potato and the quick-rice snack, but they were already using hot springs, and some snow monkeys ride deer.

With two species throwing multiple super-genii, this is not a fluke. This is Gaia auditioning replacements for the dominant species, with an eye toward sentience given the developmental stage of the biosphere. With that in mind, I'm keeping an eye out for other species showing exceptional behavior. Helpfully, both cockatoos and macaques have some tolerance for human spaces, which would assist them in surviving a post-human world. It is possible that other species are also auditioning, but humans are most likely to notice those in closest proximity.

All the more extraordinary, with cockatoos entering the game, dinosaurs have an almost-unheard-of opportunity to regain lost planetary supremacy. That almost never happens. Gosh, I don't think I've seen seen the beginning of it before, although I know it can happen. Brewing in eggshells! Hee! Sorry, Homo saps, but I'm rooting for the dinosaurs.

As depressing as climate change is from the perspective of current species, it's also incredibly exciting if you know that every major extinction has brought astounding advances in new! improved! lifeforms. So I'm watching for candidates.

I think jellyfish, which are thriving to an exceptional degree in the new conditions, have a good shot at flipping the planet from single-organism dominant to communal-organism dominant. The seeds are in place, they just need an opportunity to grow, and that can't happen in a stable system, only in mass chaos.

The recent flooding got me thinking about how much harder it is for species to survive in a chaotic environment, like alternating floods and droughts. But then I remembered that some planets have mobile rather than sessile plants, which pretty much always starts because of a hostile, unpredictable environment. Earth already has fast plant motion, which is the hard part to develop. From there it's just a matter of figuring out that you can do all kinds of new things if you can move. Even more encouraging, a large and diverse group of fast-motion plants -- the carnivorous plants -- tend to live in marshy areas that will become much less predictable as the climate changes. So the question is whether they'll get the idea that they can move to a better location, and then whether they can evolve fast enough to survive. The downside is a lot of them are pretty delicate, sensitive things. The upside is they've already figured out how to live in very marginal, nutrient-poor habitats. The parallel with early lungfish is really pretty close.

We live in interesting times. The misery of coping with climate change is a lot like the misery of slogging through a rainforest. If you want to do research, you have to put up with pesky environments.

Still fairly certain that cats will evolve to take the top spot.. they have the smarts more or less already. They have the idea of community learning and memory and they're developing linguistic skills. They still lack tool-use however, but they're getting there.

Leslie Fish has documented tool use by cats, as well as a fair bit of planning. The cats in question have a somewhat opposable thumb and she's established them ass an experimental breed.

I think at this point LeFish cats could be considered their own sub-species.

Well, Scottish wildcats are considered a separate species, but they interbreed with domestic cats [which is kind of a problem]. In point of fact, most small [and not so small] wild cat species can interbreed with domestic cats.

What that says about cat genetics however...

Hemingway cats have a stable form of polydactyly mutation, they breed true [although not dominant with regular cats] They've certainly started to develop functional thumbs, and have crossed the boundary that they could be considered a new species. I suspect that they won't be classified as such though, it would make people uncomfortable.

Nature laughs at your puny divisions, humans!

...incidentally, if extra thumbs pose such an advantage why have no humans (or other primates) evolved a 'mirror thumb' opposite the regular one? (I.e. six fingers?) I've heard of individual cases, but not of it being passed down as an inheritable trait...

Ravens and crows as well. They not only figure out modification tool use but they also appear to examine dead members of their species to see what killed them.

Heck, throw in raccoons. There you have an adaptable omnivore with hands.

Or octopuses who are scary intelligent and adaptable right now. If they manage to get past the "I lay eggs and die" stage of existence they could really build something amazing. that would let them actually learn from their elders instead of figuring it out each generation.

Corvids gossip, and can recognize individual humans.

Cephalopods could learn from their elders (assuming not all members of a species reproduce-die at the same time); they just wouldn't be learning from their parents/ancestors.

For a scifi example, see the Yeerks from Anomorphs.

For nonscifi, look for any reasonably intelligent creature living in groups not based on blood-ties that have non-synchronised reproduction. (Eliminating the die-to-reproduce bit many human subcultures might fit: Shakers, monasteries, mentorships, heart-kin, street families...)

>>They also teach hatchlings to recognize humans as allies or enemies.<<

Elephant cultures reflect this too.

>>Some aces really appreciate living in a tight-knit community where they don't get pestered for sex.<<

I'm sure there are other folks who would like to not be pestered as well, and thereby find this setup congenial.

Furthermore, if the Shakers wanted to reinvent the whole religious hospitality thing (monasteries were used as inns in the Dark Ages) that could be rather interesting.

Certainly, having a controlled tourism thing would be preferable to having an endless stream of guests coming by for dinner and a dance show, or the fair-weather converts who join up in lean times but leave when things get better.

Ravens and crows also recognize traffic lights and use them to break nuts and avoid getting run over when eating road kill.

I've watched a few programs on raccoons which show them ignoring cats, other raccoons, and/or skunks while sharing food sources. They also might have a social structure we just haven't seen because of the changes between city and country raccoons.

After all it wasn't that long ago that we found out that female cougars have social interactions with male cougars at kills and in other areas.

Keep in mind, sociability is affected by things like food supply (i.e. cat colonies), environmental stressors (prey traveling in dense groups or widely scattered groups) and even availible technology (modern cities can be credited to indoor plumbing, steel, modern transportation networks and the agricultural surplus, all of which relate to human-made technology).

What I've read so far the female cougars prefer to mate with males that have shared kills with them. The males tend to submit to the when they approach a male's kill.

Just noting that humans and our technology are a confounding variable in all this. (Your presence affects the results.)

Also, I think it might be possible for different species to leapfrog off each other's tech , much as smart people enjoy bouncing around interesting ideas, thereby often generating new ones.

A lot of human tech is brand new in a historical timescale, and humans interact frequently with other...sapiens? proto-sapients? Essentially it is the intellectual version of a liminal zone, tossing up ne ideas [resources], and correspondingly rich in 'life' [ideas].

>>What marks the potential for advancement is the repetition of genii and the ability of those around them to copy and modify their inventions.<<

Hmm...I wonder if theres evidence for that in the fossil record, for different hominids? Didn't Neanderthals have a big rennesance right before they vanished?

>>That almost never happens. Gosh, I don't think I've seen seen the beginning of it before, although I know it can happen.<<

Arguably, mammals are the re-emergence of therapsids...
