Verified step by step guidance1
Understand the question: The problem is asking for the term that describes the change in a population over time. This is a fundamental concept in biology related to how species and populations develop and adapt over generations.
Review the provided options: The options are mutation, adaptation, speciation, and evolution. Each term has a specific biological meaning, so we need to evaluate which one best fits the description of 'change in a population over time.'
Define the terms: Mutation refers to changes in the DNA sequence of an organism. Adaptation is a trait that increases an organism's fitness in its environment. Speciation is the process by which new species arise. Evolution is the change in the genetic composition of a population over time.
Match the definition to the question: The phrase 'change in a population over time' aligns most closely with the definition of evolution, which encompasses changes in allele frequencies and traits within a population across generations.
Conclude the reasoning: Based on the definitions and the context of the question, the correct answer is evolution, as it directly describes the process of change in a population over time.
