Natural selection is the key process in species evolution proposed by Charles Darwin, driven by genetic variation and advantageous traits. Understanding natural selection steps is crucial for answering exam questions involving applying the concept to different scenarios.
Insights
- Natural selection, proposed by Charles Darwin, drives species evolution through genetic variation and advantageous traits passed down through generations.
- Random mutations create genetic diversity, enabling survival of individuals with beneficial alleles, underscoring the significance of comprehending the process for successful application in diverse scenarios.

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?
