Zoology is the scientific study of animals, including their behavior, anatomy, genetics, evolution.

Zoologists study the structure and function of various organ systems and how they work together to support the life and behavior of different animal species. For example, they may examine the respiratory system of birds to understand how they are able to fly at high altitudes, or study the digestive system of herbivores to understand how they are able to extract nutrients from tough plant materials.

Another important aspect of zoology is animal behavior. Zoologists investigate the behaviors of animals in their natural habitats, studying how they communicate, mate, raise their young, and interact with other species in their environment. By observing and recording animal behavior, researchers are able to gain insights into the underlying mechanisms that drive these behaviors and how they contribute to the survival and reproduction of different species.

Zoology also encompasses the study of genetics and evolution. Zoologists investigate how genetic variations contribute to the differences in physical and behavioral traits among different animal species, and how these traits have evolved over time in response to changes in the environment and other selective pressures. By studying the genetic and evolutionary history of different species, zoologists can gain a better understanding of the origins and relationships of different groups of animals, as well as the mechanisms that drive speciation and adaptation.

Zoologists investigate how animals interact with other members of their species and with other species in their environment, as well as the ways in which they are affected by environmental factors such as climate, habitat loss, and pollution.
