10 Bizzare Evolutionary Behaviors That Help Animals Survive

6. Self-Sacrifice

In the insect world, sacrifice isn’t just a noble act—it’s a survival strategy. Worker bees will sting intruders, fully aware that the act will cost them their lives, all in service of protecting the hive.

This seemingly selfless behavior is a powerful evolutionary tool, ensuring that their genetic lineage continues even if they don’t make it out alive.
