example of allopatric speciation is that of the Galapagos Finches‚ more commonly known as ‘Darwin’s Finches’. When on his trip to the Galapagos‚ Darwin saw many different birds‚ but assumed them to be completely different‚ namely blackbirds‚ gross beaks and finches. However‚ upon later investigation he found for them to all be finches‚ but each slightly different‚ through physical characteristics‚ and so he found them to be in total twelve different species.

Charles Darwin after studying the beaks‚ concluded that each shape seemed to serve a purpose suited to the particular island (Lee 15). He concluded that finches who had short‚ fat beaks mostly ate nuts and on islands where the main food source is insects the finches had long‚ skinny beaks (Lee 15). Based on this evidence Darwin developed a theory that at some point in the past‚ one type of finch arrived at the

Owls have a suite of adaptations which help them to be successful. Owls have large eyes and holes for ears‚ a hawk-like beak‚ and a rather flat face. Most birds of prey have eyes on the sides of their heads‚ but the owl’s eyes are facing forwards to help it see better in the dark. Their eyes are also fixed inside their sockets‚ so they have to turn their whole head to look at other things. Owls can rotate their heads and necks up to 270 degrees in both directions.[1][2][3] Owls are good at

Let’s talk about the whole controversy between Nature vs. Nurture. Nature is based on DNA. Many people believe that it is DNA that decides on how humans will behave‚ what occupations they will have‚ and what their personalities will be like.
