- Big Horn Sheep reason for grouping
- Naked mole rat
- a a behavior passed from one generation to the next
through the process of learning.
- b No. While the inbreeding hypothesis predicts that one sex should
disperse it does not predict which sex.
- c in bighorn sheep the locations of feeding areas and migration routes are remembered by older members of the band and this information is transferred to subsequent generations via tradition
- d the "queen" reproduces, mother and young are fed
(but not nursed) by male and female adults of the worker caste,
another caste kept the young warm . males of this caste bred with the queen.

when individuals are in groups and predator deterrence may be
enhanced by mobbing and group defense.

5 True/False questions
Station Keeping → Used to be defined by round trip but now one-way travel also counts
Most of what is known about homing comes from studies on what species? → Birds but enough has been done on mammals to show that they
use the same mechanisms. Most mammal research has been done on bats and mice.
Richer Learning Environment for Young: → This suggested to be very important for primates and cetaceans.
Dependence on learning provides for greater behavioral plasticity, but it requires a long period of physiological and psychological dependence
Interference with Reproduction → 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
Philopatric Cooperation → Large ungulates migrate impressive distances as well.
Barren ground caribou herds move migrate 1000+ km between
wintering and summering grounds.
