#21Answer the following questions about evolution. Number responses according to the questions (1-4). (short answers are fine) How can negative traits that don't show up until old age continue in populations? (Why aren't they eliminated through natural selection?) As part of answer, provide an example. Imagine a population of mice living in a grey, rocky environment. Some mice are grey and some are brown. If natural selection occurs in this population, what would someone expect to see if you returned in 100 mouse generations? Describe what someone see in terms of fur colors in the population. Imagine a population of mice living in a grey, rocky environment. Some mice are grey and some are brown. If mutations occur in this population, what could someone see if they returned in 100 mouse generations, that would tell them mutations had occurred? Describe what they would see in terms of fur colors in the population, and how it would be different from what they would see in #2. If dark skin helps protect folate and that's so important for fetal development, why didn't all humans evolve to have dark skin? Why did humans living in the north and south evolve lighter skin?
