Name ____________________________ Date _____________________________ Section _________________________ 8th Grade Life Science Evolution: Anticipation Guide Read each of the following statements and in the right hand column (prediction) mark whether you think the statement is true or false. Once you and your partner have completed the first column, QUIETLY compare answers. We will begin the reading together, then you and your partner will read. Then, independently you will go through the rest of the reading and powerpoint notes to find out whether each statement is in fact true or false. Mark the correct answer in the actual column. In your notebook please note the page number where you found your information. You may Use pages in your book, powerpoint lessons, and interactive computer activities to guide you.

Continental drift affected the evolution of species. There is little evidence that supports the theory of evolution. Charles Darwin is famous for his theory of evolution. Evolution happens very quickly. A species is a group of similar organisms that can mate with each other and produce offspring. There are less than 1 million species of organisms on Earth. The organisms living on the Galapagos Islands were exactly the same as the fossils that Darwin found. The organisms on the islands were exactly the same as those found on the mainland. Iguanas on mainland South America have smaller claws than iguanas on the Galapagos Islands would be an example of evidence Darwin found to prove evolution. Some of the factors that affect natural selection are overproduction (competition), adaptation, and mutations. Natural selection can lead to change over a short period of time. Adaptation is a trait that helps an organism survive and reproduce. Different beak shapes is an example of a mutation. Finches (birds) that ate insects have strong, wide beaks is an example of an adaptation. Sea turtles can compete with each other by physically fighting head to head is an example of overproduction. Sheep can be selectively bred for their fine wool. Natural selection still occurs today. Geographic isolation is one of the main ways that new species form.
