A species of birds exists in stasis for many thousands of years. Suddenly, a bacteria causes their primary tree of sheltering choice to die. The birds must adapt within the environment to trees that are much higher requiring more wing strength. Some birds die. The remaining birds bodies adapt as necessary and they return to a state of stasis.

A	Phyletic Speciation
B	Adaptive Radiation
C	Convergent Evoltion
D	Divergent Evoltuion
E	Co-evolution

Explanation:

Detailed explanation-1: -Many species of animals and birds get extinct due to natural occurrences like climatic heating or climatic cooling or the changes in the sea levels. The extinction of animals and birds is because of habitat destruction also.

Detailed explanation-2: -Fifteen lakh species of animals and birds are there in the world.

Detailed explanation-3: -Etymology 1. From Middle English brid, from Old English bridd (“chick, baby bird”), of uncertain origin and relation; but its stock root is possibly onomatopoeic. Gradually replaced fowl as the most common term starting in the 14th century.

Detailed explanation-4: -Avian species diversity is a function of the number of species present (species richness or number of species) and the evenness with which the individuals are dispersed among these species (species evenness, species equitability, or abundance of each species) [8].
