concepts of the principles of evolution began. He noticed that each island had its own species of finch which were closely related but differed in important ways. For example‚ finches with longer beaks were found in environments where the nectar was deeply embedded in flowers‚ finches with sharper beaks were found in environments where seeds were the more abundant food supply. Darwin began to connect this to theories of natural selection. Darwin continued exploring these theories when he returned

Co evolution is the evolution of two or more interdependent species‚ each adapting to changes in the other. It occurs‚ for example‚ between predators and prey and between insects and the flowers that they pollinate. (www.dictionary.com) This relationship between two species allows for their existence. They work together to ensure the survival of the other. The Bumble Bee Orchid (Ophrys bombyliflora) is a species of orchid that closely resemble a female bumble bee in both looks as well as smell
