Overview
Evolutionary biology is a fascinating field that explores how life on Earth has changed over millions of years. It examines the mechanisms of evolution, such as natural selection, genetic drift, and speciation, which contribute to the diversity of species we see today. Understanding these processes ...
Key Terms
Example: The peppered moth's color change during the Industrial Revolution is a classic example of natural selection.
Example: A natural disaster that randomly kills a large portion of a population can lead to genetic drift.
Example: Darwin's finches are an example of speciation due to adaptation to different environments.
Example: The long neck of a giraffe is an adaptation for reaching high leaves.
Example: A rabbit's speed can increase its evolutionary fitness by helping it escape predators.
Example: When individuals from one population migrate to another, they introduce new alleles.
