The following
outline is provided as an overview of and topical guide to zoology:
Zoology – study of
animals. Zoology, or "animal biology", is the branch of
biology that relates to the animal kingdom, including the identification, structure,
embryology,
evolution,
classification,
habits, and distribution of
all animals, both living and
extinct, and how they interact with their ecosystems. The term is derived from
Ancient Greek word ζῷον (zōon), i.e. "animal" and λόγος, (logos), i.e. "knowledge, study".[1] To study the variety of animals that exist (or have existed), see list of animals by common name and lists of animals.
Ethology - study of animal behaviour, usually with a focus on behaviour under natural conditions, and viewing behaviour as an evolutionarily adaptive trait
Neuroethology - study of animal behavior and its underlying mechanistic control by the nervous system
Genetics - study of inheritance and gene expression
Epigenetics - study of factors affecting gene expression
