![]() ![]() Depending on environmental conditions, inherited characteristics may be advantageous, neutral, or detrimental.Traits that confer an advantage may persist in the population and are called adaptations.Over time, the proportion of individuals with advantageous traits may increase (and the proportion with disadvantageous traits may decrease) due to their chances of surviving and reproducing.Rock pocket mice, however, have had an enormous impact on science. Inherited characteristics affect the likelihood of an organism's survival and reproduction. Claim-Evidence-Reasoning: Is the rock pocket mouse population an example of Natural Selection You already have 3 claims with evidence in the previous 3. And at just 15 grams, this tiny mouse weighs about as much as a handful of paper clips.New heritable traits can result from mutations.Evolution results from genetic drift acting upon genetic variation within a population.Evolution results from natural selection acting upon genetic variation within a population.Evolution occurs through multiple mechanisms.Not all similar traits are homologous some are the result of convergent evolution. ![]() There is a fit between organisms and their environments, though not always a perfect fit.An organism's features reflect its evolutionary history.Information on controversies in the public arena relating to evolution.You take a DNA sample from a member of this new population and determine the DNA sequence of a gene known to play a role in fur color. Alignment with the Next Generation Science Standards You are studying a recently discovered population of rock pocket mice with dark-colored fur that lives on a volcanic rock. ![]()
