Babies got beat: Why rhythm might be innate

Rhythm is everywhere. Even if you don’t think you have it, it’s fundamental to humans’ biological systems. Our heartbeat is rhythmic. Speech is rhythmic. Even as babies, humans can track basic rhythm. Researchers wanted to find out if there were more layers to this: Could babies also track melody and more complicated rhythms? So they played Bach for a bunch of sleeping newborns and monitored the babies’ brains to see if they could predict the next note. What they found offers clues about whether melody and rhythm are hard-wired in the human brain or learned over time. We also get into what powers the eating habits of some snakes and chameleons, and insights into the role of sleep in problem-solving.Have a scientific question you want us to answer?
