What is natural selection?
Natural selection is the process by which species evolve over time from a common ancestor through genetic variation and advantageous traits.
How does genetic variation occur in natural selection?
Genetic variation in natural selection arises from random mutations, leading to individuals with advantageous alleles surviving and reproducing.
Why is understanding natural selection important for exam questions?
Understanding natural selection is crucial for exam questions as it involves applying knowledge to unfamiliar examples, emphasizing the steps in the process for successful answers.
What is the role of advantageous traits in natural selection?
Advantages traits in natural selection allow individuals with these traits to survive and reproduce, passing them on to future generations.
Who proposed the concept of natural selection?
Charles Darwin proposed the concept of natural selection as the process by which species evolve over time from a common ancestor.
