msspica:budaiproli:trixree:keuhkopussirotta:keuhkopussirotta:I love how both corvids and parrots are in general highly intelligent, but where corvids generally have strict hierarchies, solve disagreements in the pecking order by fighting, and have a strong dislike for anything new or foreign until they figure out how to make use of it, parrots are just here to party. The New Caledonian crow, who knows how to specifically build a tool in order to build another tool, never engages in play. These motherfuckers are smarter than some people with the right to vote, and they are Extremely Serious Birds. They don’t have time to play, they got work to do and kids to raise. And then there’s the kea, straight-up titled “clown of the mountains”, that has a specific vocalization for “playtime!”. Scientists decided to try what happens if they play the Play Call for two fully-grown adult keas that are together in an area and can clearly see there is no other, third kea to make the call, and they just go “great idea, disembodied voice! it’s TIME TO FUCKING PARTY!” and start wrestling. Imagine working really hard in order to make it into a top university to study astrophysics, making it to your first Very Serious Class, sitting down full of serious determination, and the dude next to you is taking notes without using his hands, with a glitter pen he’s shoved up his nose. And his notes are good.It’s your first day of Bird University and you already fucking hate this guy.So there’s this gene in humans called PLXNC1 or “Plexin”, right So Plexin is associated with increased neuron function and is generally thought to be correlated to human’s increased cognitive ability for the use of language, i.e., “language learning”. Super cool, right Humans aren’t the only animals with advanced language learning that have Plexin in their genome. We can actually find homologous plexin between humans and PARROTS! Using genomic alignment search tools, we can actually break down the sequence of human Plexin and directly compare it to the Plexin found in parrots. (This was actually a project I ran for an upper division genomics class, and running the program literally takes like… ten minutes.) I wanted to see how similar the plexin gene was between humans and parrots, so I queued up the human sequence against all of the available records from parrot genomes and sorted by greatest percent identity (i.e., which bird species had the closest plexin to ours) It was this funky dude right here: THAT’S RIGHT BABY! The kea, notorious for being a straight up motherfucking prank god, carries Plexin with a 79.42% identity comapred to humans’. THIS LITTLE ASSHOLE HAS A HOMOLOGOUS LANGUAGE LEARNING GENE WITH US!!!! A GENE THAT IS THOUGHT TO BE CORRELATED TO HIGHER LEVEL LEARNING AND INTELLIGENCE!!!!! AND THEY USE THEIR INTELLIGENCE TO WREAK HAVOC ON TOURISTS Also these guys have been found to literally have predictive reasoning skills, which we consider REALLY FUCKING ADVANCED for a lot of animal species. They pass the Aesop’s fable test with flying colors. They’re so goddamn cool, I love them so much. The kea really said: “I will use my superior intelligence to have a good fucking time” and that’s so powerful honestly kea <3
