Name ____________________________ Date _____________________________ Period _________________________ Chapter 5, Section 1: Anticipation Guide 1. Read each of the following statements and in the left hand column mark whether you think the statement is true or false. 2. Once have completed the first column, QUIETLY compare answers with a partner at your table. 3. We will begin the reading together, then, independently, you will go through the rest of the reading to find out whether each statement is in fact true or false. Mark the correct answer in the 3rd column. In the last column please note the page number where you found your information. Use pages 140-150 to guide you. T/F Prediction Statement Introduction T/F Page Actual Number T Charles Darwin sailed on the HMS Beagle. F The Galapagos Islands are off the coast of Australia. Darwin’s Obs. F The HMS Beagle sailed straight from England to the Galapagos Islands. F Similarities and Diff There are less than 1 million species of organisms on Earth. A species is a group of similar organisms that can mate with each other and produce fertile offspring. 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. Adaptations T F F T F Finches that ate insects have strong, wide beaks. T Adaptation is a trait that helps an organism survive and reproduce. Evolution F Different beak shapes is an example of a mutation. F Evolution happens very quickly. T Darwin is famous for his theory of evolution. F Sheep were selectively bred for their fine wool. Natural Selection F Alfred Russel Wallace wrote The Origin of Species. T Some of the factors that affect natural selection are overproduction, competition and mutations. Overproduction F Sea turtles compete with each other by physically fighting head to head. Selection F Natural selection can lead to change over a short period of time. T Natural selection still occurs today. Evolution in Action How do new species form Continental drift F There is little evidence that supports the theory of evolution. T Geographic isolation is one of the main ways that new species form. T Continental drift affected the evolution of species. 4. Define these terms on your green vocabulary sheet. Species Adaptation Evolution Natural selection variation
