Principles of Evolution 10.1 Early Ideas About Evolution Georgia Standards: SB5.a; SCSh7.c (refer to pg. 298 in the text) Based on the standards listed above, write a 2-4 sentences summary that describes what tasks or concepts you should be able to complete, explain, or perform at the end of this section _________________________________________________________ _________________________________________________________ _________________________________________________________ _________________________________________________________ _________________________________________________________ _________________________________________________________ Scientist Key Points: What ideas did each scientist propose about evolution? Carolus Linnaeus Georges Louis Leclerc de Buffon Erasmus Darwin JeanBaptiste Lamarck 1 _______________ is the process of biological change by which descendants come to differ from their ancestors. ________________________ proposed the Theory of Evolution by __________ ___________. Because a coyote and a wolf are the same ___________ they can reproduce and have fertile offspring. Georges Cuvier observed ___________ located in different strata of the earth to develop the theory of ___________________ which states that natural disasters such as ___________ and _________________ caused species to ________________________________________________. James Hutton proposed the theory of __________________. How is this theory different from the one Georges Cuvier proposed? _________________________________________________________ _________________________________________________________ _________________________________________________________ ____________________ states that the geological processes that form the earth are __________ through time. 10.2 Darwin’s Observations Georgia Standards: SCSh7.b (refer to pg. 302 in the text) Based on the standard listed above, write a 1-2 sentences summary that describes what tasks or concepts you should be able to complete, explain, or perform at the end of this section. _________________________________________________________ _________________________________________________________ _________________________________________________________ What is the difference in the physical traits of an individual from those of other individuals in the group to which it belongs? _________________ 2 Darwin traveled to the ____________ Islands where he observed differences in species of tortoises and finches. Complete the table below by describing which variations he observed in each. Tortoises Finches What contributed to the variations in the tortoises and the finches? _________________________________________________________ _________________________________________________________ _________________________________________________________ An _______________ allows a an organism to better survive in its environment and can lead to genetic change in a population over time. Darwin observed fossils and experienced an earthquake during his travels. How did these things influence his thoughts about evolution? _________________________________________________________ _________________________________________________________ _________________________________________________________ _________________________________________________________ 3 10.3 Theory of Natural Selection Georgia Standards: SB5.d (refer to pg. 304 in the text) Based on the standard listed above, write a 1-2 sentences summary that describes what tasks or concepts you should be able to complete, explain, or perform at the end of this section. _________________________________________________________ _________________________________________________________ _________________________________________________________ _________________________________________________________ What is artificial selection? _________________________________________________________ _________________________________________________________ Name one of example of artificial selection in each of the following organisms/species (you may have to use the internet or other resources): 1. Bird: ________________________________________________ 2. Dog: ________________________________________________ 3. Fruit: _______________________________________________ 4. Vegetable: ____________________________________________ The ability of traits to be passed down from one generation to the next is called _______________. What acts as the selective agent in artificial selection? _______________ What acts as the selective agent in natural selection? ________________ Natural selection of characteristics and traits is most influenced by whether or not they give the individual ______________ over the other individuals in the environment. Pretend you are a dog breeder. List three traits that are heritable that you would select to make a PERFECT house dog. 1. ____________________________________________________ 2. ____________________________________________________ 3. ____________________________________________________ 4 Within any ______________ of species, there will be noticeable variations. Write a sentence in your own words that summarize each of the four principles of natural selection. (refer to pg. 306) Variation Overproduction Adaptation Descent with Modification What does the term fitness mean? ____________________________________________________ ____________________________________________________ Read the sections on pg. 308-309 titled “Changing Environments” and “Adaptations as Compromises”. Why is the panda’s “thumb” considered an adaptive compromise? ____________________________________________________ ____________________________________________________ ____________________________________________________ 5 10.4 Evidence of Evolution Georgia Standards: SB5.c (refer to pg. 310 in the text) Based on the standard listed above, write a 1-2 sentences summary that describes what tasks or concepts you should be able to complete, explain, or perform at the end of this section. _________________________________________________________ _________________________________________________________ _________________________________________________________ What four types of evidence did Darwin use to support his argument for evolution? 1. _________________ 2. _________________ 3. _________________ 4. _________________ Write the answers from #1-4 from above in each of the circles below. Then, read pages 310-313 and provide a summary in the shaded area that describes how Darwin used each one to support his theory of evolution. 6 Vocabulary Tip: Homo- same, like Ana- proportionate Study Tip: Homologous structures share a common origin but may not be adapted for similar functions. Analogous structures are adapted for similar functions but do not have a common origin. Homologous Structures Look at figure 10.11 on page 312 What similar structures are shared between the human hand, bat wing, and the mole foot? ____________________________________________________ What different functions are performed by the human hand, the bat wing, and the mole foot? Human Hand: __________________________________________ Bat wing: _____________________________________________ Mole foot: ____________________________________________ What body part of a dolphin is homologous to the structures shown in the figure? ___________________________________________ Analogous Structures Look at figure 10.12 on page 313 What similar function is shared between the bat and insect? ____________________________________________________ What is different about the bat and the insect? ____________________________________________________ ____________________________________________________ 7
