Ascientist wrote a paper titled “directional selection in action” after observing a population of mice for 15 years. the mice typically preferred to eat berries, although a few would also eat insects. after a drought in year 3, the scientist observed that more mice were eating insects. by year 10, most of the mice in the population ate insects in addition to berries. which best describes her article?

Although the two theories differ on the evolutionary path of dinosaurs, they agree that

Creation of an unnaturally uniform sample to represent a diverse populationcan be avoided by: a. including only willing b. asking another scientist for .c. choosing only identical participants. d. selecting individuals at random.

1. variations in a population of moths allow for some of its members to be able to adapt to environmental changes. the better adapted of the moths will be able to survive the change and thus prevail as the “fittest” of the species. (a) describe three mechanisms in which variation can occur within a species population. (b) explain which mechanism or mechanisms would be responsible for the survival of a population of peppered moths better than white moths in an environment affected by industrial soot. justify your answer.
