It is the formation of new species from existing ones.
B
It is the random change in allele frequencies due to chance events.
C
It is the movement of genes between populations through migration.
D
It is the process by which individuals with advantageous traits are more likely to survive and reproduce.
Verified step by step guidance1
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 provided statements: Analyze each option to determine which one aligns with the definition of natural selection.
Eliminate incorrect options: For example, 'formation of new species' describes speciation, not natural selection. 'Random change in allele frequencies' refers to genetic drift, and 'movement of genes between populations' refers to gene flow.
Focus on the correct statement: The correct description of natural selection is the process by which individuals with advantageous traits are more likely to survive and reproduce.
Conclude that natural selection is a non-random process driven by environmental pressures, favoring traits that enhance survival and reproduction.
