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:
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
