Answer :

At the genetic level, biological evolution is a change in allele frequencies over time.

What is biological evolution?

In populations of organisms, biological evolution is the change in hereditary features through successive generations. Adaptation is a crucial evolutionary process in which natural selection modifies variance in the fitness of characteristics and species to make them better suited for survival in particular ecological settings. Therefore, understanding the mechanics of evolution requires understanding how developmental changes are mediated.

Model organisms are used frequently to study biological processes. A model organism is a species that is thoroughly researched in the lab with the hope that the findings will be applicable to various biological processes.
