Living in groups helps the animals to hunt down large prey for food. It plays an important role in their evolution over a period of time. All animals live in groups as they are raised in them and later breed with their partners. Living in herds also leads to the animals to learn sharing their kill rather than competing with their companions. Animals in herds usually move around together, searching for food. Thus animals form groups for survival, they can help each other raise the young, hunt, keep watch, gather food, find shelter, and survive. Animals in groups have more eyes looking for predators or prey. They also have less work to do individually because they can share the workload.
