Special Report: Lichens, corals, and many plants host beneficial bacteria or fungi within their bodies and depend on them for vital nutrients; and different species of microorganisms living within a host may be interdependent on one another.

Wilson, who is known for his studies of ants and bees that have yielded insights into human existence, has shown that our evolution from tribal into a global society increasingly favors compassionate and cooperative over callous and competitive approaches to human interaction.
Partners may also manipulate each other in ways that enhance cooperation in the short term, without necessarily favoring evolution of cooperation over generations.
One less competitor to worry about.
Interestingly, similarities among all mitochondria suggest that animals, plants, and fungi evolved from a one-time origin of this ancestral symbiosis between two microbial species. Using more host resources lets parasites produce more offspring, but overexploitation shortens host life span, reducing the amount of time the parasites have to reproduce.
Indeed, multicellular organisms serve as the ultimate example of cooperation on a cellular level, with millions, billions, or even trillions of cells working together to form the tissues and organs of a complex individual.The Survival of the Fittest?
This bottleneck means that a hypothetical mutation that allows a strain to gain a slight advantage over a competitor by exploiting the host does not greatly improve its chances in reaching the next generation. Genetic similarity among multicellular individuals also plays a major role in the evolution of cooperation on the macro level.

Many animals follow this basic philosophy. Gorrell et al.

When I initially presented some of my ideas about the power of compassion in success and achievement, my critics pointed out that Darwinism made my argument weak: Selfish people and even bullies may win a couple of rounds or sets in the game of life, but they rarely win the match or game; it is the compassionate people who win.
Comparing soybean and alfalfa root nodules in normal air to nodules on the same plant in an atmosphere with only traces of nitrogen, we found that rhizobia reproduced less frequently when they could only fix enough nitrogen for their own needs, with no surplus for the plant. According to biologists from Darwin to E.
