Kind: research · Impact: low

## In brief

- Biologists have long assumed it is very rare for two species separated for millions of years to independently develop the same genetic changes.
- A new study of the DNA of ancient jellyfish reports that evolution repeats itself, according to Earth.com's coverage.
- The coverage frames the finding as suggesting evolution may be more predictable than expected.

## Why it matters

If independent lineages repeatedly arrive at the same genetic changes, it challenges a common assumption about how predictable evolution is, which matters for researchers studying convergent evolution and genome-based inference.
