Describe how a change in DNA helped a new trait evolve.

Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes. Genetic variations can arise from gene mutations or from genetic recombination.

Explanation:

a normal process in which genetic material is rearranged as a cell is getting ready to divide. These variations often alter gene activity or protein function, which can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection). Over time, as generations of individuals with the trait continue to reproduce, the advantageous trait becomes increasingly common in a population, making the population different than an ancestral one. Sometimes the population becomes so different that it is considered a new species.

A sudden change in DNA is called a mutation. When a change in DNA occurs, a new trait evolves. This trait maybe desirable or not.
