Having twins is rare for non-human primates unless they are in which type of social group?
A
Fission-fusion societies
B
Solitary groups
C
Cooperative breeding groups
D
Dominance hierarchies
Verified step by step guidance1
Understand the concept of cooperative breeding groups: These are social systems where individuals other than the parents help in raising offspring. This behavior increases the survival rate of twins or multiple offspring.
Compare cooperative breeding groups with other social structures mentioned: Fission-fusion societies involve flexible group sizes and are not typically associated with raising twins. Solitary groups consist of individuals living alone, which makes raising twins highly challenging. Dominance hierarchies focus on social ranking and competition, not cooperative care.
Recognize that cooperative breeding groups provide shared responsibilities, such as feeding, protection, and care, which are essential for the survival of twins in non-human primates.
Understand why twins are rare in non-human primates: Raising twins requires significant resources and care, which is difficult in social structures without cooperative support.
Conclude that cooperative breeding groups are the most suitable social structure for raising twins due to the shared caregiving responsibilities among group members.
