What are species and what are its role in evolution?
Species is a group of individuals who are able to interbreed or breed with each other in nature. This means that the same species are able to reproduce with one another. For instance whales are not a species because blue whales are not able to breed with humpback whales, so for example blue whales are a species. Another example are wolves. The red wolf and the gray wolf can not reproduce with each other, so the are different species. There are some species who are able to interbreed with other species, like the ligon, it is an offspring of the lion and the tiger. But they are not able to reproduce, even with other ligons. Another hybrid is the grolar bears, which is a offspring of a grizzly and a polar bear. But the same thing happens to the grolar bears as the ligons, they are not able to reproduce. Species role in evolution is that evolution wouldn't take place. This is because evolution happens in species. Without species no traits will pass down through generations.

Adaptation
What is adaptation and its role in evolution?
Adaptation is the condition of organisms being well designed for life in their habitat/environment. Some adaptation are good and others are bad. Adaptation all depends in the environment the organism lives in. For example if a organism lived in snow, the organism would probably have strong legs. Or if an organism lived in dark trees, the organism might have dark skin to camouflage. Adaptations role in evolution is that it helps the organism be the most adapted to its environment leading to natural selection which is a process leading to evolution. So without adaptation there would be no natural selection, which means no evolution.
