Evolution of new physical traits in mollusks has declined and grown more predictable over time

Mollusks’ Evolutionary Innovation Fades Over 540 Million Years

The fossil record of mollusks, one of Earth’s most enduring animal groups, reveals a striking pattern in the development of new physical traits. Researchers examined this extensive history spanning 540 million years and uncovered a clear trajectory: bursts of novelty in the early stages gave way to longer intervals between innovations. This shift highlights how ...
