Question
Storage of excess carbohydrates in the diet in the form of fat would have helped human populations survive famine. However, this
process is also a risk factor for obesity and type 2 diabetes in modern populations. Modern populations vary greatly in the
prevalence of type 2 diabetes, but there is no evidence that alleles increasing type 2 diabetes susceptibility have been under
positive selection in human populations. Which of the following is the best inference we can draw from these findings.
Selected answer will be automatically saved. For keyboard navigation, press up/down arrow keys to select an answer.
