What
A new study on 574 million-year-old fossils suggests clone-based reproduction kept early animals stable until sexual reproduction boosted diversity, explaining a long pause in evolution.

Where
Mistaken Point in Newfoundland, Charnwood Forest in the United Kingdom ·
Why
Early animals reproduced asexually via stolons, which limited dispersal and competition, thereby slowing evolutionary pressures.
The Frontline Impact
How this affects you
This research provides a new explanation for a long-standing puzzle in evolutionary biology, showing that the ecological structure of early animal communities, specifically their reproductive strategy, held back significant evolutionary diversification.
