How does natural selection affect animal behavior and how behaviors can affect the survival of an animal species?

Well, technically what happens in natural selection is that the organisms with favorable traits that help them survive live long enough to pass their traits down through offspring. All the good traits passed down to the next generation help them. It would bring certain behaviors that are crucial for survival. The traits, if passed down for long enough, can affect the whole species, and eventually, the whole species can have that trait (ex. speed, agility, etc.)

The answer would be cstep by step explanation: all of the other animals developed their features while the salamander was born with them
