U3 KA6 Social Behaviours

Question 1

What behaviours are adapted for group living in animals?

Answer 1

Animals living in social groups have behaviours such as social hierarchy, co-operative hunting, and social defence.

Question 2

What is altruism?

Answer 2

Altruism is a behaviour that harms the donor individual but benefits the recipient.

Question 3

What is kin selection altruism and how does it influence survival?

Answer 3

Kin selection occurs when behaviour appears altruistic, and the donor benefits by increasing the chances of survival of shared genes in the recipient’s offspring or future offspring.

Question 4

What is the structure of society in social insects?

Answer 4

In social insects, only some individuals (queens and drones) reproduce. Most members of the colony are sterile workers who cooperate with close relatives to raise offspring (which they do to benefit the survival of shared genes).

Question 5

What is parental care in primates?

Answer 5

Primates have a long period of parental care, allowing them to learn complex social behaviour.

Question 6

How does primate behaviour support social hierarchy?

Answer 6

These behaviours support the social hierarchy, reduce conflict through ritualistic display and appeasement, and form alliances to increase social status.
