New evidence links simpler venom to island prey
New research is challenging the idea that snake venom evolution always favors complexity. Scientists found that some snakes shift toward simpler venom blends tailored to specific prey, particularly on isolated islands. This “ecological efficiency” reduces wasted effort while preserving effectiveness, and genetic flexibility allows future changes. Coevolution with prey further steers which venom traits survive.
- Complex venom is not always the best strategy
- Simpler venom can target specific prey more efficiently
- Island populations show a strong move toward streamlined venom
- Prey-driven coevolution and genetics shape venom changes
