There was a change in the environment between
generations 10 and 30. the change
caused a genetic mutation
eliminated a recessive trait
favored trait a
favored trait b

These changes are likely genetic mutations

Evolution is the process of change in all life forms from one generation to the next, and evolutionary biology studies how this evolution takes place. Every generation of organisms inherits traits owned by their parents through genes. Changes (called mutations) in this gene will produce new traits in the offspring of an organism. In an organism's population, some traits will become more common, while others will disappear. traits that help the survival and reproduction of organisms will be more likely to accumulate in a population than unfavorable traits. This process is called natural selection. The income of more offspring than the number of parents along with the inheritance of these traits is an additional fact about life that supports the scientific basis of natural selection. In a long time, this isolated population will become a new species.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
