Claim:
Group behavior can increase the chances for an individual and a species to survive and reproduce.
Evidences for the claim:
As the claim suggests that group behavior is favorable for organisms, it increases their chance of survival and reproduction. First of all we have to understand what is group. Group is a collection of same kind of organisms that travel, live as well as perform daily life work together.
- When organisms are living in a large group they have better chances to find a mate.
- Living in a group helps the organisms to save them from the attack of predators, because unity is strength.
- Large groups have more power to access food sources and can find ample source with the assistance of fellow members, than solitary animals.
Additional reputable evidence:
We have often seen the birds that they form a V shape when they fly in air in a group. Now, this group formation in V helps those birds to navigate their pathways in a better way. They have more chances to reach in their destination even if that is far off from their place of departure, because the whole group's navigating ability help to reach a destination faster. They are better able to reproduce, survive there.
Similarly when fish swim in groups, they can avoid the attack of predators and are better able to swim for a longer period of time to reach theri destination.
Conclusion:
Group behavior equips the organisms with protection and support. It better adapts an organism to survive the harsh effects of the environment.
