Punctuated equilibrium, a concept introduced by paleontologists in 1972, reimagines evolution’s tempo as a stochastic burst rather than a steady beat. A new model finds support for their theory in both molecular and fossil data. @jakebuehler.bsky.social reports www.quantamagazine.org/the-sudden-s...
