Meaning of Zoology

What is Zoology:

Zoology is a branch of biology that is dedicated to the study of animals. The word zoology comes from the Greek ζωον (zoon), which means "animal", and -λογία (-logy), which translates "study" or "science".

The main objective of zoology is the examination of the morphological and anatomical description of the various animal species: their reproduction, development, behavior and distribution.

In zoology there are different branches that are responsible for the various aspects of animals, among which we can mention:

  • Zoography, which is dedicated to the description of animals.
  • Animal anatomy, which is responsible for observing the organisms of animals.
  • Animal physiology, which analyzes the chemical and physical functioning of the organism of animals.
  • Zoogeography, which looks at the relationships between animals, their environment, and their geographic distribution.
  • Palaeozoology, which studies fossil animals.

Likewise, there are other branches of zoology dedicated to working with specific species of animals.

Zoologists are the specialists in charge of the biological taxonomy of all species of animals, both living and dead. Some zoologists work as museologists, and are in charge of the maintenance and description of zoological collections.

The first zoologist in history was Aristotle, who, with the creation of the taxonomy, detailed numerous species and elaborated an outline of the animal classification, although many of his conclusions lacked scientific rigor and were rejected during the Renaissance, time in which zoological investigations began to adopt a scientific character. In addition to this, the discovery of the microscope by Antón van Leeuwenhoek in those years allowed the study of the tissues of animals and beings until then unknown.

See also Taxonomy.

Likewise, the British naturalist Charles Darwin made very important contributions to zoology with the Theory of the evolution of species, which indicates that each individual of a species develops a quality that allows it to adapt to its habitat, survive and reproduce, and inherit that adaptive virtue from its descendants; on the other hand, the worst adapted individuals do not survive and, therefore, do not leave offspring, causing the extinction of their species.
