Is kindness good or bad for survival?

As we all know, bees are kamikazes. They die after stinging. However, we don't necessarily see the evolutionary paradox behind this behavior. Indeed, the particular case of stinging bees contravenes the general laws of evolution. We need to explain it if we are to preserve these laws.

The general law of evolution applies to all animal species. Each individual is guided by an internal mechanism that drives it to try to survive and reproduce. Within a given species, the longer an individual lives, and the more young it has compared to other individuals of the same species in the same kind of territory, the more viable it is. The specific evolutionary term for viability is «fitness». Let's take the example of two female giraffes: a giraffe that has lived ten years and had three cubs has a fitness pl
