Imagine that millions of years ago, there was a population of fish that could live in shallow water in a region with many shallow lakes. The lakes often reduced to a tiny puddle of mud in the summers. Many of the fish died in the summers. The only individuals that survived each year were those that were able to breathe in the muddy water, and also forage for food better than the others in the highly competitive environment. One day, a baby fish was born that was able to breathe air due to a genetic mutation. This fish reproduced and passed on its air-breathing genes to future generations. Soon, in the summers, more and more fish were surviving because the air-breathing fish were able to live on land and forage on land, and not have to compete with the water-living fish. What is the mechanism by which these air-breathing fish are increasing in numbers over the years
