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.
