AI Insight
Research from Bangor University indicates that European viper venoms likely evolved primarily to subdue prey rather than to cause pain in potential threats. The study challenges the common assumption that pain infliction was a key evolutionary driver in venom development for these snakes. The findings suggest that the painful effects humans experience from viper bites may be an incidental consequence rather than an intended defensive function.
Why it matters
This research reshapes our understanding of venom evolution and could inform more effective treatments for snakebite victims by focusing on the actual biological targets of the venom. It may also reduce unnecessary fear around these species by clarifying that pain is not their venom's primary purpose.
Understand the Science
For many people, the fear of venomous snakes is linked to one thing: pain. Yet new research led by scientists at Bangor University suggests that, for Europe’s vipers, at least, causing pain may never have been a driving force in the evolution of their venom.
