Types and Processes of Evolution

Questions and Answers

What is Convergent Evolution?

Process by which two species evolve in response to changes in each other.

The evolution of similar features in independent evolutionary lineages. (correct)

Evolutionary change above the species level.

When two or more species sharing a common ancestor become more different over time.

What is Divergent Evolution?

When two or more species sharing a common ancestor become more different over time.

What is Co-Evolution?

Process by which two species evolve in response to changes in each other.

Study Notes

Types of Evolution

Convergent Evolution: Distinct species independently evolve similar traits due to similar environmental pressures or ecological niches.
Divergent Evolution: Species that share a common ancestor gradually evolve different traits, increasing diversity among species over time.

Interactions in Evolution

Co-Evolution: Two or more species influence each other's evolutionary path, creating adaptations in response to one another's changes.

Unique Evolutionary Processes

Reverse Evolution: A species may lose complex traits or organs that were present in its ancestors, indicating adaptation or change in necessity.

Scale of Evolution

Microevolution: Refers to small-scale changes within a species, commonly observed over short time frames, leading to variations within a population.
Macroevolution: Encompasses large-scale evolutionary changes that occur above the species level, often involving the emergence of new species and significant shifts in biodiversity.
