Cover –Natural Selection (Predator/Prey); Video on evolution of the rock pocket mice; Population
Estimation; Tapped conservation video
Possible Format – Fill-in the blank; Labeling; Short answer; Matching
Natural selection (Predator/Prey):
 Know what is meant by the terms evolution, natural selection, and co-evolution
 What is the source of variation in phenotypes in a population? (mutations)
 Know that mutations alone create new variations and natural selection edits the unfit
phenotypes
 Use the evolution of the rock pocket mice in the video that we watched as an example of
natural selection
o What color were the mice to begin with, before the lava flow that created the volcanic
rocks in New Mexico? Remember they blended in with the sandy soil.
o How was the black colored mice created? It was through random mutation, an error in
DNA replication that is passed on to new generation.
o After the black volcanic rock was formed, who selected the “unfit” white mice in the
volcanic areas leaving only the black “fit” ones to survive? It was the predators, since
white ones were the most visible. This is why today almost all mice caught in this region
is black.
o Remember what Dr. Sean Carroll said at the end of the video “While mutation is
random, natural selection is not”. Natural selection in this case was dictated by the
color of the background soil, in other words, the environment.
 Define predation
o List three types of predation
o What do these linkages move through the food chain?
o List four reasons why predation is important
 In the predator/prey lab, know what the following items represent in nature
o Spoons, forks and knives
o M&Ms ,red beans, lentils and macaroni
o The cloth used
o One round
 How did this lab demonstrate natural selection?
 Give other examples of natural selection
Estimating population size:
 Who are the scientists that estimate population size?
 Define a population
 Why is that various sampling techniques and estimation methods are necessary to determine
population size
 Know the two methods of pop estimation. Give examples of species suitable for estimation
using each method.
o What is the grid system used for?
o Why use the “Capture, Mark & Recapture” method?
