The Five Fingers of Evolution Quiz

Study Notes

Key Concepts of Evolution

Evolution: Defined as a change in the genetic makeup of a population across generations.
Five Processes of Evolution: Involves horizontal gene transfer, random genetic drift, mutation, migration, and natural selection, which drive evolutionary changes.

Mechanisms of Evolution

Mutation: Refers to a permanent alteration in the DNA nucleotide sequence, contributing to genetic diversity.
Migration: Describes the relocation of animals from one area to another, often influenced by seasonal changes in environment.

Types of Evolution

Macroevolution: Encompasses evolutionary changes at or above the species level, such as the evolution of dinosaurs.
Microevolution: Involves evolutionary changes occurring within a species, exemplified by the case of peppered moth adaptations.

Evolutionary Relationships

Homology: Highlights similarities among species due to shared ancestry; an example includes the pentadactyl limb found in various vertebrates.
Analogy: Refers to similarities in traits between species that arise from convergent evolution rather than shared ancestry; bird wings and bat wings illustrate this concept.

Convergent Evolution

Defined as the independent evolution of similar traits in organisms from different backgrounds, often in response to similar environmental challenges or ecological niches.

Description
