  1. Matrilineally
  2. Another way to maintain direction
  3. Social terrestrial species
  4. Requirements for piloting
  5. Piloting
  1. a most mammalian social systems are arrange matrilinearlly; mothers and their offspring may stay together and groups are this composed of mothers, daughters, aunts, and nieces
  2. b tend to forage above ground in open habitats during the daytime
  3. c requires a mental map of
    the terrain but does not require a compass. In principal it could be
    used for longer trips
  4. d Distant landmarks have been demonstrated to be used by some
  5. e Another way to maintain direction is to use the sun or stars as a
    compass and maintain a constant angle to it while traveling. This
    requires an internal clock to compensate for the sun moving at about 15° per hour

5 Multiple choice questions

  1. Parental care that is misdirected to
    non-offspring (suckling the wrong
    baby) and killing of young by
    non-parents are the biggest costs
    in this category
  2. No. While the inbreeding hypothesis predicts that one sex should
    disperse it does not predict which sex.
  3. A group of individuals of the same species that is organized in a cooperative manner, extending beyond sexual and parental behavior.
  4. three types of mice:
    1) Wild caught in grassland
    2) Offspring of wild-caught parents
    3) Grassland mice reared in the lab for 20 generations
  5. - a sense of direction (some form of compass)
    - a sense of location (understand where it is starting from)

5 True/False questions

  1. Protection Against PredatorsA coalition controls a pride until a new one takes over or they
    leave to take over another pride (usually before their daughters
    start mating). New coalitions usually kill all of the young cubs so
    breeding males usually stay until their cubs are old enough.


  2. Most of what is known about homing comes from studies on what species?Carnivores, Cetaceans, and Primates


  3. Outbreeding Depressionmatings between members of different populations within
    a species leads less-fit offspring. . Members of a population may possess adaptations to local
    conditions that are potentially lost through outbreeding.
    Two areas may differ in temperature, humidity, or types of food
    and if each population is genetically adapted to these conditions
    they would be better off mating with individuals with those same


  4. Genes and the Environment (Nature versus Nurture)If two animals reared from birth under identical environments
    differ in habitat preference when adults, the conclusion would be
    that the differences resulted from hereditary factors


  5. Reason for dispersal (reduce Competition)with conspecifics for food, shelter, or mates. Most mammals are polygynous and males may be forced to disperse as they compete for access to females
