mm- animal behavior Flashcards
What are sterility and suicide examples of? A Mutualistic behaviour B Spitefulness C Extreme altruism D Selfish behaviour
C extreme altruism
“A gene can maximise its transmission by maximising the reproductive success of the individual” This describes?
A Direct fitness
B Indirect fitness
C Kin selection
direct fitness!
How is Hamilton’s rule calculated?
“r * B - C > 0 It identifies the conditions where altruism will spread due to kin selection. Where:
r - coefficient of relatedness between actor and recipient
B - benefit to recipient
C - cost to actor”
What is the coefficient relatedness for a parent and their offspring?
0.5
What is the coefficient relatedness for aunt/uncle and niece/nephew?
0.25
“A gene can maximise its transmission by maximising the reproductive success of other individuals who share copies of that gene” this describes?
A Direct fitness
B Indirect fitness
C Kin selection
indirect fintess
what is the coefficent relatedness for siblings
0.5
"Behaviour that has a positive effect on self and a positive effect on others is? A Mutualistic B Selfish C Altruistic/cooperative D Spiteful
a mutualistic!
Behaviour that has a negative effect on self and a positive effect on others is? A Mutualistic B Selfish C Altruistic/cooperative D Spiteful
altruism
“When will altruism be favoured?
A (rB) - C = 0
B (rB) - C > 0
C (r*B) - C < 0”
B when rB> C so the secon option - benefit to recipent is more than cost to the altruist
Behaviour that has a negative effect on self and a negative effect on others is? A Mutualistic B Selfish C Altruistic/cooperative D Spiteful
D SPITE
Behaviour that has a positive effect on self and a negative effect on others is? A Mutualistic B Selfish C Altruistic/cooperative D Spiteful
B SELFISH
what is a common pitfall of studying animal behavior
aonthropomorphism - naive extrapolation from human to animal e.g. smiling may NOT be happy
how do ritualised signals differ from cues?
they are more noticble (conspicuious) have little variation (sterotype) they are repetative they can be DRAMATIC /alerting > prevents ignoring from happening and increases efficacy and honesty BUT also manipulation
how are natural and sexual selection similar?
variation between individuals affecting
> survival or reproductive success
that is inherited
