Forget the sperm race: Fertilization may depend on teamwork
Millions of sperm do not always compete alone—some species send them into action as coordinated teams.
Millions of sperm do not always compete alone—some species send them into action as coordinated teams.
The short version
- A sweeping evolutionary study found that this cooperation is widespread among arthropods and has repeatedly emerged and vanished over hundreds of millions of years.
- The discovery challenges the classic “fastest sperm wins” story and could influence future fertility research and pest-control strategies.
- Fertilization is commonly portrayed as an intense contest in which millions of sperm race toward a single egg.
What happened
New research from evolutionary biologists at Syracuse University, University of Siena, Italy, and University of Szeged, Hungary, points to a more complex picture. In some species, reproductive success may depend not only on competition, but also on sperm working together.
Why it matters
The researchers examined arthropods, the enormous group of animals that includes insects, spiders, crabs and centipedes.
