There are a number of evolutionary hypotheses that researchers have developed to better understand the high prevalence of complex diseases like type 2 diabetes and obesity across populations today. The best explanation for this high prevalence of complex diseases is: A. Speakman's hypothesis B. Meyer’s gene hypothesis C. Thrifty gene hypothesis D. Drifty gene hypothesis E. Neel's hypothesis

Is gene transfer a form of eugenics? Is it advantageous to use gene transfer to eliminate some genetic disorders? Can this and other technology be used to influence the evolution of our species? Should there be guidelines for the use of genetic technology to control its application to human evolution? Who should create and enforce these guidelines?

Please answer the question below; specifically "what are the four observations that inexorably led to the conclusion that species evolve by natural selection?" Thank you so much.
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)
Do you think the human race is continuing to evolve in a Darwinian, genetic sense? Are the genes of our species changing? Do not just write "yes" or "no," but explain why you think so. In addition, include in your explanation of how the mechanisms of evolution, such as natural selection, would be at play.
Some critics have warned that the use of gene therapy to correct genetic disorders will affect the course of human evolution. Evaluate this criticism in light of what you know about population genetics and evolution, distinguishing between somatic gene therapy and germ-line gene therapy.

Please help with the following: The EDAR gene carries one of the most highly differentiated SNPs in the genome: Val370Ala nonsynonymous variant (rs3827760). This variant: A. has a very high frequency in native Australians B. appears to be the product of positive selection C. is a consequence of genetic drift D. shows no contemporary geographical variation E. appears to be the product of negative selection
Why is it important to study evolution? Explain in three paragraphs.
A form of learning disabilities and speech impairment results from a recessive mutation in the HERC2 gene. The next 4 questions are about this mutation. In a small Amish village in Ohio, about 5 per 1000 births are affected with this disorder. Assume Hardy Weinberg equilibrium. What is the frequency of the dominant WT HERC2 allele in this small village? A form of learning disabilities and speech impairment results from a recessive mutation in the HERC2 gene.

Apply the VIDA table to the evolution of sickle cell disease to justify whether it is an instance of evolution by natural selection. Answer the following questions. Is there variation in this trait in the population? How exactly does it vary? Is the trait at least partly inherited? Is there selection for this trait in a particular environment? (What is the selective pressure? And how does a trait give an advantage or disadvantage in that environment?) What is the evidence that this trait makes organisms better adapted to their environment?
Which of the following best explains the role mutations play in natural selection?A. Most mutations are negative and result in the extinction of the entire speciesB. Mutations may appear for one or two generations, but they usually disappear quickly.C. If the environment changes, an existing organism develops a mutation that will help them to survive.D. Some mutations give individuals an advantage in their environment, allowing them to survive and reproduce.D is my answer is it correct?
