Symbiosis is the ecological relationships between two or more different species. These relationships can benefit both species, benefit one species at the expense of the other, or it can benefit neither species. There are many different type of symbiosis that ecologists are able to classify. One ecological relationship is called mutualism. This is when both species benefit. Another ecological relationship is called commensalism. This is when one species benefit and the other one is unaffected. The last ecological relationship is called parasitism. This is when one species benefits and the other is harmed.

Symbiosis plays a major role in coevolution between flowers, and the animals that pollinate them. In addition, according to the biologist Lynn Margulis, she believes that symbiosis is a major driving force behind evolution. She believes that evolution is strongly based on the interaction and mutual dependence among organisms. However, some people have used symbiosis as evidence against evolution. One such example is that creationists argued that since neither organism can survive without the other, they must have come into existence at exactly the same time. Thus, symbiosis plays an important role in ecology, yet there is some arguments pertaining to whether or not symbiosis, is evidence for or against evolution.
