Pattern of Evolution

Selection that favors extreme opposite traits.

• Directional Selection

• Disruptive Selection

• Stabilizing Selection

The process by which an ancestral species gives rise to new species that are adapted to different environmental conditions and are less alike.

• Divergent Evolution

• Co-Evolution

• Convergent Evolution

When two species evolve together and there is a mutual evolutionary influence between both species.

• Allopatric Speciation

• Co-evolution

• Convergent Evolution

• Divergent Evolution

Evolution that is slow and steady with little changes over a long period of time.

• Gradualism

• Punctuated Equilibrium

• Allopatric Speciation

• Divergent Evolution

This occurs when a species separates into two separate groups which are geographically isolated from one another.

• Co-evolution

• Divergent Evolution

• Adaptive Radiation

• Allopatric Speciation

When a new colony is started by a few members of the original population and the colony has reduced genetic variation.

• Genetic Variance Disadvantage

• Founder Effect

• Adaptive Intonation

• Divergent Evolution

Body parts that perform a similar function but differ in structure.

• Vestigial Structures

• Analogous Structures

• Homologous Structures

• Variant Structures

Body parts that are similar in structure and position but different in function.

• Vestigial Structures

• Analogous Structures

• Homologous Structures

• Variant Structures

• Are body parts that have lost their original function through evolution.

• Vestigial Structures

• Analogous Structures

• Homologous Structures

• Variant Structures
