Primary sources means that it is original article or book created by an individual or sometimes a group of people. What types of primary sources are available? It might be surprising to know that a novel is a primary source. Other types of primary sources are paintings created by the artist. If it were a photocopy of the painting, then it would be a secondary source. Some other primary sources are letters, films, short stories, plays, poems, photographs, court cases, journal articles, newspaper events, and speeches. For instance, a speech by President Bush would be a primary source.
Secondary sources are sources that are written about primary sources. Secondary sources analyze, interpret, and discuss information about the primary source. If a magazine writer wrote about the speech President Bush gave on September 11th, it would be a secondary source. The information is not original, but it is an analysis of the speech.
Answer:
Coevolution
Explanation:
Coevolution is a type of evolutionary change pattern that occurs when the interaction between two species of organisms brings about a change in the both species. In other words, both species of organisms evolve together as they interact together. The effect of the activity of one brings about a change in the other, and vice versa.
An example of coevolution can be seen in a flowering plant and pollinator relationship, just as seen between the hummingbird and flowering plants. The hummingbird evolve longer beaks in order to obtain nectar from the flower, while the flower in return evolve to grow deeper that contains sweeter nectars for the bird. Other pollinators without this adaptation of the hummingbird, like bees, would find it difficult to obtain this nectar from the flower.
