Biology Terminology

Artificial Classification:

• Classification based on genetic similarities.

• Classification based on random traits.

• Classification based on superficial characteristics or convenience.

• Classification based on ecological roles.

Adaptive Radiation:

• Radiation that causes mutations in species.

• The rapid evolution of species from a common ancestor into various forms.

• The adaptation of species to urban environments.

• The gradual change of a species over time.

Convergent Evolution:

• Evolution of similar traits in unrelated species due to similar environments.

• Evolution due to converging rivers.

• Evolution of different traits in closely related species.

• Evolution based solely on genetic drift.

Polyploidy:

• A condition where organisms have a single set of chromosomes.

• A condition where organisms have two sets of chromosomes.

• A condition where organisms have three sets of chromosomes.

• A condition where organisms have more than two sets of chromosomes.

Epigenetics:

• Study of gene expression changes not caused by DNA sequence alterations.

• Study of genetic mutations.

• Study of inherited characteristics.

• Study of ecological genetics.

Homologous Structures:

• Structures unique to each species.

• Similar structures in different species due to a common ancestor.

• Structures with different origins but similar functions.

• Structures used for the same purpose in different species.

Sympatric Speciation:

• Speciation within the same geographic area from a single ancestral species.

• Speciation due to climate change.

• Speciation due to geographical barriers.

• Speciation based on behavioral differences.

Analogous Structures:

• Structures that are unique and not found in other species.

• Structures that have a common function and common evolutionary origin.

• Structures that are different in different species but have a similar function.

• Structures that are similar in appearance but different in function.

Natural Classification:

• Classifying organisms randomly.

• Classifying organisms based on their natural relationships and evolutionary history.

• Classifying organisms based on man-made criteria.

• Classifying organisms based on their size and shape.
