Biology studies the diversity of life and its unifying characteristics, which include?

Evolutionary characteristics

Explanation:

In Biology, we study about the enormous diversity of life from microscopic organisms to the perfect creation human and to giant extinct dinosaurs. In fact it includes diversity at every level of organization.

The unifying theory which is studied in Biology is evolution which explains that this diverse life is still having a common origin or is united at a single point. Below are some of the important evolutionary characteristics which unify the diversity of life.

Hope it help!

Evolution study, cell study, homeaostatsis  and genetics

Explanation:

Biology deals with unification in biological diversity among species. There are four ways of unifying biology a) evolution, b) Cell study, c) homoeostasis and d) genetics

As per the theory of Charles Darwin, it is believed that all species have evolved from single common ancestors who later got diversified through the processes of natural and artificial selection. Theory of evolution determines how cellular divisions during sexual and asexual reproduction carry forward genetic material to offspring. Sexual reproduction causes variation in offspring in order to make them adaptable to the existing environment
