M16L1 History of Classification

Open Ended

How and why do we classify animals?

To provide an organized way of learning and communicating about all types of organisms.

Multiple Choice

______ is the structure and form of an organism or one of its parts

• typology

• morphology

• biology

• ecology

To "morph" means to change SHAPE or APPEARANCE. Morphology or the shape/appearance of an organism can help us group certain organisms together as part of the same classification.

Multiple Choice

______ _______ gives each species a scientific name that has two parts.

• monomial nomenclature

• binomial nomenclature

• trinomial nomenclature

• quadratic nomenclature

•Binomial nomenclature gives each species a scientific name that has two parts.

•The first part is the genus name. The second part is the specific epithet, or specific name, that identifies the species.

Multiple Choice

________ is the grouping of objects or organisms based on a set of criteria

• taxa

• domains

• classfication

• binomial nomenclature

Multiple Choice

_____developed the first widely accepted classification system.

• Lemarck

• Darwin

• Linnaeus

• Aristotle

Aristotle developed the first widely accepted classification system.

•Organisms were classified as plants or animals.

•Animals were divided into “red blooded” and “bloodless” and by habitat.

•Plants were divided by size and structure.

​The table shows how Aristotle may have classified different plants and animals.

Multiple Choice

______ based his system on observations of morphology and habitat.

• Lemarck

• Darwin

• Linneaus

• Aristotle

Multiple Choice

_______ is the discipline of biology primarily concerned with identifying, naming, and classifying species based on natural relationships. 

• taxonomy

• domain

• kingdom

• binomial nomenclature

•Taxonomy is the discipline of biology primarily concerned with identifying, naming, and classifying species based on natural relationships.

Early Systems of Classification

​Modern Classification Systems

•The study of evolution during the 1800s added new dimension to Linnaeus’s system.

•Scientists began to infer evolutionary relationships in their classification systems.

•Today’s classification systems are rooted in the work of Linnaeus but have been modified to reflect our knowledge of evolutionary ancestry.

•Taxonomic categories used by scientists are part of a nested-hierarchical system.

•Each category is contained within another, and they are arranged from broadest to most specific.
