Zoology is a biological science that pertains to animals.


"A recent comparison of the draft sequences of mouse and human genomes has shed light on the selective forces that have predominated in their recent evolutionary histories. In particular, mouse-specific clusters of homologues associated with roles in reproduction, immunity and host defence appear to be under diversifying positive selective pressure, as indicated by high ratios of non-synonymous to synonymous substitution rates. These clusters are also frequently punctuated by homologous pseudogenes. They thus have experienced numerous gene death, as well as gene birth, events. These regions appear, therefore, to have borne the brunt of adaptive evolution that underlies physiological and behavioural innovation in mice. We predict that the availability of numerous animal genomes will give rise to a new field of genome zoology in which differences in animal physiology and ethology are illuminated by the study of genomic sequence variations."[1]

Theoretical zoology[edit]

Def. "that part of biology which relates to the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct"[2] is called zoology.

Def. the "study of mammals"[3] is called mammalogy.

Def. "the scientific study of birds"[4] is called ornithology.

Def. "branch of paleontology that focuses on studying dinosaurs"[5] is called dinosaurology.

Def. "the study of fish"[8] is called ichthyology.

Considered a "living fossil" because it is an ancient class of lobe-limbed fish that went extinct more than 70 million years ago, the first living coelacanth was caught off the east coast of South Africa near the Chalumna River in 1938.

Today, at least two major populations of coelacanths are known: one off east Africa, and another near Indonesia. Coelacanths cannot be eaten; their flesh contains an oil that is highly distasteful to human beings.

This specimen in the image above weighs 160 pounds (72.6 kg) and measures 5.5 feet (1.67 m) in length.

Def. study of the echinoderms is called echinodermology.

Def. the "scientific study of butterflies and moths"[9] is called lepidopterology.

The "Acanthocephala, are descended from, and should be considered as, highly modified rotifers. Genetic research has determined this is unequivocal; the Acanthocephalans are modified rotifers".[10]

Def. the "study of all life or living matter"[11] is called biology.
