3 Questions
What is natural selection and how does it contribute to evolution?
Natural selection is the process by which individuals with beneficial traits have a higher chance of surviving and reproducing, passing those traits onto the next generation. This leads to the gradual evolution of a species.
What is the role of mutations in evolution?
Mutations are the second cause of evolution. They occur when errors in replicating sex cells happen. If a mutation is beneficial, it provides a reproductive advantage within the species and can become a new trait over time.
What is gene flow and how does it impact genetic variation?
Gene flow is the spread of new genetic material between populations of the same species. It commonly occurs through migration and increases genetic variation by making populations more similar to one another.
Test your knowledge on natural selection and mutations in this quiz! Learn about how variation among individuals and beneficial traits contribute to survival and evolution. Explore the concept of "survival of the fittest" and how good traits are passed down through generations. Discover the role of mutations as a second cause of evolution.
