- In your group, consider the following statement: "Mutations are random, natural selection is not." What does that statement mean?Discuss the significance of mutations and explain the role of the environment in the evolutionary process. (Hint: Consider Lenski's study and what is demonstrated. Do not re-tell Lenski’s study)Explain the role of gene mutation in evolution.
- According to the Hardy-Weinberg Equilibrium Equation, all of the following slow down or stop evolution EXCEPT (choose as many as apply): Group of answer choices very small population very large population no one leaves or comes into the population everyone has equal numbers of offspring there are no mutations there are lots of mutations there is non- random matingConsider the four postulates of natural selection. How have humans manipulated each of these postulates in natural or artificial systems?"evolution is an integrated process" and uses sickle-cell allele as an example. In just 2-3 sentences, trace the various factors that influence evolution based on this example. I just want to know how Darwin, Mendel, gene flow, genetic drift, mutation, recombination and even the environment serve to create evolution. Thank you.
