Imagine a population of small animals. All of the animals in this population have short legs. They all eat the leaves off of the low shrubs in their environment. One animal happens to be born with a mutation that gives it very long legs. It is the only individual in this population with this mutation, and it makes it very hard for it to eat the leaves so low to the ground. But suddenly there is a fire that burns all of the shrubs, so the only food source is now up in the low tree branches. How might this individual animal with the long- leg mutation affect the entire population?
