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. Neel's hypothesis b. Speakman's hypothesis c. Meyer’s gene hypothesis d. Thrifty gene hypothesis e. Drifty gene hypothesis

Are gene mutations caused by selective pressures in the environment? In other words, do gene mutations arise in an organism out of need or want? Group of answer choices A. No, because gene mutations are not purely random. B. Yes, because gene mutations are not purely random. C. No, because gene mutations are purely random. D. Yes, because gene mutations are purely random.
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?

Of the following, which is the least plausible hypothesis for why natural selection has not eliminated genes for male homosexuality? a. Perhaps the relatives of a homosexual male have more than an average number of children. b. Homosexual people might spread their genes by helping their brothers and sisters rear their children. c. Maybe there is no gene for homosexuality. Instead, an environmental event produces an epigenetic effect that can be transmitted from one generation to the next. d. Some homosexual men have children.
