NU665 WEEK 1 CERTIFICATION REVIEW
SET 2026 ANSWERS GUARANTEED PASS
⫸ Evolution. Answer: Coined by Charles Darwin: Natural selection,
survival of the fittest
a change in the genetic composition of a population over time
It unites ethology, population biology, ecology, anthropology, game
theory, and genetics
⫸ aggression. Answer: aggression serves both to increase territory and
to eliminate competitors. Defeated animals can emigrate, disperse, or
remain in the social group as subordinates
⫸ Altruism. Answer: behavior that reduces the personal reproductive
success of the initiator while increasing that of the recipient
working for others even if it means self sacrifice
Within the group the altruists are at a severe disadvantage but they help
the group as a whole succeed (example bees serving the queen)
⫸ twin studies on intelligence. Answer: twin studies suggest that
intelligence is based 2/3 genes and 1/3 environment
, multiple twin studies suggest high rates of similarities in neuropsych
testing despite being raised seperately
⫸ ethology. Answer: study of animal behavior
⫸ Konrad Lorenz. Answer: ethology (animal behavior); studied
imprinting and critical periods in geese
"Critical Period" the time shortly after birth when imprinting occurs
⫸ consumatory response theory. Answer: Phase of behavior whereby
the energy driving the appetitive phase is released. Involves the
perception of sign stimuli, the activation of the innate releasing
mechanism (IRM), and the performance of the fixed action pattern
(FAP)
⫸ fixed action pattern. Answer: a sequence of unlearned or genetically
determined acts directly linked to a simple stimulus
species specific stereotyped movements
⫸ innate release mechanism. Answer: sensory mechanism selectively
responsive to specific external stimuli and responsible for triggering the
stereotyped motor response
