How do certain animal behaviors increase the probability of reproduction?
[Clarification Statement: Examples of behaviors that affect the probability of animal reproduction could include nest building to protect young from cold, herding of animals to protect young from predators, and vocalization of animals and colorful plumage to attract mates for breeding.
How is group behavior beneficial for survival?
Groups can help animals find mates.
They typically form groups because they share the same food source, which consists of algae and shrimp. One of the benefits of living together is that they do not need to travel far to find mates. This helps them survive because if they had to travel far they could get eaten!
How does living in a group like lions increases the fitness of the species?

Hunting as a group means there is a better chance that the lions have food when they need it, and it is less likely that they will get injured while hunting. … The lionesses work together to hunt and help rear the cubs.
Can behaviors evolve in a population?
To the extent that behaviors are controlled by genes, they may evolve through natural selection. If behaviors increase fitness, they are likely to become more common over time. If they decrease fitness, they are likely to become less common.
What behavior increases a bird’s chances of reproducing?
Example: Singing helps male zebra finches attract mates, increasing the chances that they will reproduce. Singing is part of an elaborate courtship ritual that entices the female to choose the male.

What are the advantages of animals living in groups?
