Behavior that benefits other organisms may sometimes also benefit the individual. In such cases, no conflict arises. For example, mutualisms are common in nature: insect pollination of flowers; animal dispersal of seeds; the ant-acacia symbiosis; and various endosymbionts (bacteria/termites, algae/nudibranchs; mitochondria; chloroplasts). Such interactions between species illustrate how organisms may adapt through mutually beneficial behavior, even where the exchange is not conscious.
