Part Two: Answer the following questions in the spaces provided. Make sure that you answer each question completely. Each question is worth 5 marks

11. List and Explain the major points of Darwin’s Theory of Evolution: 12. Today, the “North American Strawberry” is somewhat small and red in colour. It has a small green leafy top and

a semi – sweet taste. Two Hundred years ago, North American strawberries were white and quite large (almost the size of an apple). They had a very sweet taste and fragrant thick green and white top that attracted insects and small bird. Nearly one hundred and fifty years ago, a parasite transmitted by the birds attracted to these strawberries caused a blight that systematically killed nearly 90% of this strawberry population. The strawberries that tended to be smaller in size and contained a less leafy green top were not affected by the blight as they did not attract the parasite carrying birds. Further, these smaller strawberries tended to have a slightly red colour and a less sweet taste as they contained a lower sugar concentration. Explain how Natural Selection can be used to explain the transformation of the North American Strawberry.
