There are 4 evolutionary mechanisms : Natural selection, gene flow,mutations and genetic drift.

In our case, we are talking about the natural selection.

Natural selection is an evolutionary mechanism that favors individuals that are the most fit for their environment. Certain individuals in a population can have a trait that gives them a survival advantage over the other individuals in the population. Natural selection favors these individuals and they leave more offspring and are more successful. In the case of lung fishes, their lungs were a trait that gave them a huge advantage because it enabled them to live outside the water and use new resources available on land.
