Speciation Vocab

Biodiversity

• The variety of life in the world or in a particular habitat or ecosystem.

• The evolution of a new species that occurs because of changes in gene flow between populations of ancestral species.

• The large scale evolutionary changes that take place over long periods of time.

• Species that have similar features, indicating common ancestor or same developmental origin.

• Similar structures in organisms without shared ancestry.

Analogous Structures

• The variety of life in the world or in a particular habitat or ecosystem.

• The evolution of a new species that occurs because of changes in gene flow between populations of ancestral species.

Convergent Evolution

• Two organisms without a common ancestor who end up more alike as they adapt to similar ecological niches.

• When two species evolve based on their interactions with and effects on one another.

• Two organisms with a common ancestor who end up as different species; initially similar populations gain differences over time.

• Evolution of an animal or plant group into a wide variety of types adapted to specialized modes of life.

• Speciation generally occurs uniformly, via a steady and gradual transformation.

Adaptive Evolution

• Two organisms without a common ancestor who end up more alike as they adapt to similar ecological niches.

• A model where there are long periods of little evolutionary changes and short bursts of rapid changes.

• Two organisms with a common ancestor who end up as different species; initially similar populations gain differences over time.

• Evolution of an animal or plant group into a wide variety of types adapted to specialized modes of life.

• Speciation generally occurs uniformly, via a steady and gradual transformation.
