Another thought-provoking Quora question: Are there any hereditary units in music? The question details give some context: In his blog post “The Music Genome Project is no such thing,” David Morrison makes an edifying distinction between a genotype and a phenotype. He also makes the bold statement “there are no hereditary units in music.” Is …

The evolutionary origin of laughter
In his book Sweet Anticipation: Music and the Psychology of Expectation, David Huron does some fascinating speculation about the evolutionary origin of laughter.
Where does the “Egyptian” melody originally come from?
I know this melody as the cartoon snakecharmer song. Here’s a kid playing it on bass clarinet: I’ve always wondered where the Egyptian melody came from. It turns out to be hundreds of years of old, and goes by many different names. You can find an excellent capsule history of it in William Benzon’s book …

Why do I grimace when I concentrate?
The parts of your brain that do your abstract thinking are very tightly interconnected with the parts that control your muscles. In fact, some of that abstract thinking is done by the same brain regions that control your muscles. We don’t yet know why a specific brain region produces a given specific thought, but the …
What is the evolutionary purpose of dreaming?
Dreaming doesn’t have an evolutionary purpose per se. It’s just an emergent property of the piecemeal way our brains have evolved, from the older and more automatic systems out to the newer, learning-enabled systems. I’ve seen it suggested by several different scientists that most animals go about their waking lives in a state similar to …

Why has the human brain evolved so much more than any other animals?
The human brain isn’t “more” evolved. It’s just differently evolved. Our intelligence has its obvious advantages, but it carries some significant costs. Like Joshua Engel says, the big brain is metabolically expensive. It makes childbirth much harder for humans than for other mammals, too. Human babies have to be effectively born prematurely in order to …

Does teaching Intelligent Design in schools really damage science?
You don’t go to high school biology class to learn particular facts; you go to understand the general framework of evolutionary theory. Rather than contradicting any single fact, Intelligent Design undermines the entire intellectual basis of biology.
Is Richard Dawkins helping science through his attacks on religion?
I would wish for Dawkins to use more emotional sensitivity and compassion when dealing with religious people, because his hostile tone gets in the way of his invaluable message. His condescending attitude toward believers, epitomized by calling atheists “brights,” is seriously counterproductive. I’m concerned that he’s unnecessarily confrontational and inflammatory in his TV appearances, op-eds …

Building a better dopamine awareness campaign
I’ve been intrigued by Charles Lyell‘s self-described “dopamine awareness campaign,” trying to show how all of our social behaviors boil down to a desire for gratifying dopamine shots. The campaign doesn’t seem to be going so well; see, for example, the collapsing of his recent answer to Why do people contribute reviews of restaurants/theatres/events etc? …

Why does listening to music sometimes make you feel high?
I’ve been lucky enough to experience heightened and altered consciousness from music making, listening and dancing. Chasing that feeling motivates me to keep making and studying music, in spite of the lousy pay. I’m reading a wonderful book right now by William Benzon called Beethoven’s Anvil. Benzon looks at the state of brain research and …
