THIS WEBSITE IS UPDATED FREQUENTLY (so be sure to check it
frequently)
Be sure to review evolutionary theory and speciation
natural selection, genetic drift, founder effect,
etc.

Evolution of Social Behavior (from: Goldsmith and
Zimmerman)
part 1 (evolution of altruism)
part 2 (parent-offspring
conflict)
part
3 (sex ratio adjustment)
Evidence
of
convergent character displacement in release vocalizations
Assignment due:
This
term: QUESTIONS in ANIMAL SOCIAL BEHAVIOR
Contrasting models for the evolution of social organization:
fitness of the group vs. fitness of the gene
models by Wynne-Edwards,
Hamilton, Trivers
tests of hypotheses:
Systems to be examined:
-cooperative
breeding (experimental
evidence-helping; subordinate
males; warblers;
life history; allomothering-langurs
Altruism
in Forest Chimpanzees: The Case of Adoption, Helping
in cooperatively breeding longtailed tits: a test of Hamilton’s
rule
Kinship
affects investment by helpers in a cooperatively breeding bird
-parent-offspring conflict (infanticide in
langurs) (is
infanticide adaptive?) (non-offspring
nursing-cute guys)

Evolution of eusociality
(from: Goldsmith and Zimmerman)
Conditional
manipulation of sex ratios by ant workers
Origin of
eusociality-by Wilson and Holldobler (2005)-kin selection
doesn't cut it
Kin
selection is key to altrusim-by Foster et al (2005)- yes it
does
