Discuss the evolutionary 'pros and cons' of animals living in groups. Name three animal behaviours are necessary for group living? For each behaviour, describe the governors of behaviour that may result in group living

Answer: The pros to animals living in groups are that they have an increased rate of survival. They also have an increased rate of reproduction. The young are also better protected. Groups of animals can also make bigger kills. Their success rate of kills is high because they work together to take down their kill. The cons to animals living in groups are that if they get a disease, the transmission would be rapid. Three animal behaviours that are necessary for group living are communication, cooperation, and reproduction. Without communication, animals would not be able to live in groups. An example of animal communication would be birds using certain calls in order to let other birds know that danger is ahead. Cooperation is needed for animals to live in groups. This would include dividing tasks, defending each other, and even sharing food. An example of this can be seen in meerkats. Young meerkats watch over baby meerkats, while the older meerkats are out looking for food. Reproduction is also important as it keeps the group growing and strong. This can be seen in almost every species. Males always tend to make themselves look better than other males in order to attract a female
