“Head trainer Teri Turner Bolton presses her palms together over her head, the signal to innovate, and then puts her fists together, the sign for “tandem.” Comparative psychologist Stan Kuczaj records several seconds of audible chirping between [the dolphins] Hector and Han, then his camera captures them both slowly rolling over in unison and flapping their tails three times simultaneously. [...] Either one dolphin is mimicking the other [...] or it’s not an illusion at all: When they whistle back and forth beneath the surface, they’re literally discussing a plan.” [more inside]
Daniel Dennett, known for having previously explained thinking, religion, and consciousness, recently spoke at the Royal Institution where he did a most excellent job of explaining memes [1-hour video].
Lovatt reasoned that if she could live with a dolphin around the clock, nurturing its interest in making human-like sounds, like a mother teaching a child to speak, they'd have more success. - stories from the NASA- funded project to teach Dolphins to talk using LSD (among other methods. )
Staying_On-Topic in r/intelligentanimals posts a huge number of links explaining why Corvids (crows, ravens, magpies, etc) are amazing.
Daniel Soar on the militarisation of metaphor: Spies aren’t known for their cultural sensitivity. So it was a surprise when news broke last month that IARPA, a US government agency that funds ‘high-risk/high-payoff research’ into areas of interest to the ‘intelligence community’, had put out a call for contributions to its Metaphor Program, a five-year project to discover what a foreign culture’s metaphors can reveal about its beliefs.
The origins and evolution of human intelligence: parasitic insects? viruses? mushrooms? neural darwinism? foraging? machiavellian competition? emergence? or something else?
Language started with emotional signaling. That's the thesis of a new book, The First Idea: How Symbols, Language, And Intelligence Evolved From Our Primate Ancestors To Modern Humans, by Stanley I. Greenspan and Stuart G. Shanker.
Lived emotional experience is key to language learning, the authors suggest. "Mathematicians and physicists may manipulate abstruse symbols representing space, time, and quantity, but they first understood those entities as tiny children wanting a far-away toy, or waiting for juice, or counting cookies. The grown-up genius, like the adventurous child, forms ideas through playful explorations in the imagination, only later translated into the rigor of mathematics."The book is very ambitious, and I don't think we'll ever know where language came from, but this sounds like a more fruitful line of thinking than Chomsky's deus ex machina "language gene" mutation.
