Introduction
Nova Labs: The Evolution Lab is an online educational platform that aims to teach students about evolution in a fun and interactive way. Lesson 5 focuses on natural selection, adaptation, and the concept of fitness. In this blog post, we will provide you with the answer key for Lesson 5 of Nova Labs: The Evolution Lab.
Answer Key
Question 1: What is natural selection?
Answer: Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce.
Question 2: What is an adaptation?
Answer: An adaptation is a characteristic or trait that helps an organism survive and reproduce in its environment.
Question 3: What is fitness?
Answer: Fitness is the ability of an organism to survive and reproduce in its environment.
Question 4: What is the difference between natural selection and artificial selection?
Answer: Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce. Artificial selection, on the other hand, is the process by which humans selectively breed plants or animals for specific traits.
Question 5: What is the relationship between natural selection and adaptation?
Answer: Natural selection is the process that drives adaptation. Organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to their offspring.
Question 6: What is convergent evolution?
Answer: Convergent evolution is the process by which unrelated organisms evolve similar adaptations in response to similar environmental pressures.
Question 7: What is divergent evolution?
Answer: Divergent evolution is the process by which a single species evolves into two or more different species over time.
Question 8: What is speciation?
Answer: Speciation is the process by which a single species evolves into two or more different species over time.
Question 9: What is a homologous structure?
Answer: A homologous structure is a structure that is similar in different species because it is inherited from a common ancestor.
Question 10: What is a vestigial structure?
Answer: A vestigial structure is a structure that no longer serves its original purpose, but is still present in the organism.
Conclusion
In conclusion, Nova Labs: The Evolution Lab Lesson 5 provides a comprehensive understanding of natural selection, adaptation, and the concept of fitness. By going through the answer key provided in this blog post, you will be able to assess your understanding of the topic and improve your scientific knowledge. We hope this article has been helpful to you.
