plants produced large tough seeds and small soft seeds. Most members of a population of finches are found to have small beaks while a smaller portion of the group have large beaks. The islands experienced a drought that negatively impacted the community of plants that produced small soft seeds leaving the island with plants that produced large tough seeds. After the drought, it was observed that the finches with smaller beaks were reduced and the majority of finches were found to have large beaks.

Conservation Biology

The study of how to prevent the loss of biological diversity on the planet is called conservation. Biological diversity, also termed biodiversity, consists of various life forms found in a specific location or across the entire planet, including ecosystems, species, populations, and genes. Conservation thus aims to protect the diversity of life at all levels of biological organization.
