Natural selection is best described as:
A

Verified step by step guidance

Understand the concept of natural selection: Natural selection is a mechanism of evolution where individuals with traits that provide a survival or reproductive advantage are more likely to pass those traits to the next generation.
Compare the options provided: Analyze each option to determine which one aligns with the definition of natural selection.
Option 1: 'The process by which individuals with advantageous traits are more likely to survive and reproduce' - This matches the definition of natural selection, as advantageous traits increase survival and reproduction chances.
Option 2: 'The random change in allele frequencies in a population over time' - This describes genetic drift, not natural selection, as natural selection is not random but based on advantageous traits.
Option 3: 'The intentional breeding of organisms by humans for specific traits' - This describes artificial selection, not natural selection. Option 4: 'The movement of individuals into or out of a population' - This describes gene flow, not natural selection.
