Introduction to Animal Taxonomy

Classification of Living Organisms

• Aristotle suggested classifying animals based on their characteristics and behaviors.

Contributions to Classification

• The first scientist interested in classifying living organisms from animals and plants was Aristotle.

John Ray's Contribution

• John Ray's idea contributed to the development of a clear definition of species.

Aristotle's Classification

• Aristotle's classification of animals included characteristics such as mode of reproduction, diet, and habitat.

17th Century Classification

• Throughout the 17th century, the scientific community took up the task of classifying living organisms.

Animal Taxonomy

• According to Dr. Ebrahim Alhousini's lecture, the primary focus of animal taxonomy is to identify and classify animals based on their characteristics.

Definition of Species

• John Ray was the first to develop an accurate definition of species.

Basis of Modern Classification

• The basis of the system of classification used nowadays, according to Linnaeus, is the similarity of structures and characteristics among organisms.

Binomial Nomenclature

• The system of Binomial nomenclature devised by Linnaeus is composed of a two-part name consisting of a genus and species.

Modern Classification

• In modern classification, characteristics such as molecular biology, evolutionary relationships, and fossil records are used in addition to morphological and anatomical features.

Grouping Genera

• Related genera are grouped into families, which are further grouped into orders.

Classification Hierarchy

• Classes constitute a level in the classification hierarchy, which is divided into smaller groups such as orders, families, and genera.

Phyla Formation

• Higher taxonomic groupings known as phyla are formed based on body structure and developmental patterns.

Subkingdoms

• Larger groups known as subkingdoms or branches are based on cellular structure and body organization.

Development of Binomial Nomenclature

• Linnaeus devised the system of Binomial nomenclature by using a combination of genus and species names.

Modern Classification Basis

• The classification is based upon the characteristics and evolutionary relationships among organisms in modern times.
