The study of carpenter ants' lifesaving amputations has left scientists in awe. These tiny insects have evolved to perform surgery on their colony siblings to prevent the spread of infection. With a survival rate of over 90%, it's clear that these ants are skilled surgeons. But what makes them so advanced?

One reason is their unique salivary secretions, which have antimicrobial properties. This is common among many animal groups, including primates. However, most ants in the genus Camponotus, which carpenter ants belong to, don't have this gland. So, they may have evolved their surgical skills as a workaround.

The ants' ability to adapt to different injuries is also impressive. They alter their treatment depending on where the injury is. For example, if the femur is damaged, they amputate near the body, removing the whole leg. This ensures the patient is more likely to survive.

But what's even more remarkable is the ants' social skills. They work together to achieve tasks, and their evolution as a social insect has likely encouraged them to learn skills to protect ants in their colony. In fact, research has shown that animals who live in tight groups are more susceptible to outbreaks of disease. So, the ants' collective action to prevent the spread of disease is crucial.
