Where
Mistaken Point in Newfoundland, Charnwood Forest in the United Kingdom ·
Why
Early animals primarily reproduced asexually through stolons, creating connected clones that shared nutrients and reduced competition, thus limiting the pressure for evolutionary change.
The Frontline Impact
How this affects you
This research offers a new explanation for a long-standing puzzle in early animal history, suggesting that the ecological structure of the first animal communities, rather than a lack of life, delayed evolution.
