3 SCIENCE 8 Examining Ev idence E.3 Name: Date: Homeroom: Evolution OBJECTIVES: By the end of class, students will be able to SWBAT analyze and evaluate the scientific evidence provided by the fossil record. DO NOW 1. The diagram below shows a population of adult giraffes over time. Letters A, B, and C represent three time periods. Use Darwin s theory to explain what has occurred over the generations. 2. Brainstorm how the fossil record could be used as evidence to support the theory of evolution. 3

What it means Particular details HOMOLOGOUS STRCUTURES: o Whales, bats, hippos, and people all have the same bones in their front appendages What it is EVIDENCE #2: EMBRYOLOGY EMBRYOLOGY: Dolphins vs Humans What it means Particular details Studying the embryological development of living things provides clues to the evolution of present-day organisms. During some stages of development, organisms exhibit ancestral features in whole or incomplete form. 4

6 INDEPENDENT PRACTICE Directions: Summarize what you learned today in the space below. You may use words, pictures, charts, or a combination of these. Focus on the following for your summary: What evidence do scientists use to determine common ancestors among species? Explain how each type of evidence is used to demonstrate evolution. 6

7 Case study: Land-living ancestors of whales Fossils offer crucial clues for evolution, because they reveal the often remarkable forms of creatures long vanished from Earth. Some of them even document evolution in action, recording creatures moving from one environment to another. Whales, for example, are beautifully adapted to life in water, and have been for millions of years. But, like us, they are mammals. They breathe air, and give birth to and nurse live young. Yet there is good evidence that mammals originally evolved on land. If that is so, then the ancestors of whales must have transitioned to the water at some point. As it happens, we have numerous fossils from the first ten million years or so of whale evolution. These include several fossils of aquatic creatures such as Ambulocetus and Pakicetus, which have characteristics now seen only in whales especially in their ear anatomy but also have limbs like those of the land-living mammals from which they are clearly derived. In 2007, scientists identified a possible link between land mammals and whales. Called raoellids, these now -extinct creatures would have looked like very small dogs, but were more closely related to hooved animals the group that includes modern-day cows, sheep, deer, pigs and hippos. Scientists found that molecular evidence also suggests a deep evolutionary connection between whales and these hooved animals. One raoellid, Indohyus, is similar to whales but has some differences (ears, teeth, bone thickness) from hooved animals. These indicators suggest that this raccoon-sized creature spent much of its time in water. Therefore, Indohyus could be the transition organism between land and sea. 7

8 1. What is the claim being made in the text and what evidence supports this claim? 2. Interpret the fossil record shown in the case study, which indicates the evolution of the modern whale. Note at least two specific changes in the structure/characteristics over time. 3. The passage states that molecular evidence was used to support the connection between whales and hooved animals. Identify the type of molecular evidence we have learned about that can be used to indicate relationships. 8

9 The forelimbs below all have a similar structure (A), yet each one is found in a different species (Bird, bat, cat, whale, and human). These structures are known as HOMOLOGOUS STRUCTURES, or body parts with similar structures found in different species. The word homologous, coined in about 1656, derives from the Greek homologos, where homo = same and logos = relationship. Homologous structures can indicate evolutionary relationships between organisms. 4. Scientists use both the fossil record and homologous structures as evidence that evolution occurs. Fossils are remnants of skeletons from ancient organisms that are preserved underground. When a scientist examines homologous structures they might also look at bones, but how are homologous structures DIFFERENT from fossils? 5. What does it mean if species are said to have common ancestors? 6. Take a closer look at the bone from the whale. Notice that whales, like humans, have five finger like structures inside their fin. How does this homologous structure help support the theory of evolution? 9

10 HIGH SCHOOL CHALLENGE From Water to Land: Our Finned Ancestors The animals we are most familiar with are tetrapods they are vertebrates (they have backbones), four limbs, and they live on land. That includes humans, almost all domestic animals and most of the wild ones that any child would recognize: mammals, birds, amphibians and reptiles. The vast majority of vertebrates, however, are not tetrapods, but fish. There are more kinds of fish, in fact, than all the species of tetrapods combined. Evolutionary Biologists believe that all life actually began in the sea. Indeed, through the lens of evolution, tetrapods (humans and most other animals) are just one branch of the fish family tree! In other words, tetrapods are the relatives of fish but happen to be adapted for life out of water. The first transition from water to land took place more than 360 million years ago. It was one of the most demanding such moves ever made in the history of life. How did fins become legs? And how did the transitional creatures deal with the demands of land life, from the dry environment to the weight of gravity? It used to be thought that the first land creatures were stranded fish that evolved to spend more and more time ashore, returning to water only to reproduce. Over the past 20 years, palaeontologists have uncovered fossils that have turned this idea upside down. The earliest tetrapods, such as Acanthostega from around 365 million years ago, had fully formed legs, with Acanthostega, an early tetrapod toes, but retained internal gills. These gills would have soon dried out if this creature was on land for a prolonged period of time. This lead scientists to believe that fish evolved legs long before they came on land! The earliest tetrapods did most of their evolving in the more forgiving aquatic environment. Coming ashore seems to have been the very last stage of their evolution. Researchers suspect that all tetrapods evolved from creatures called elpistostegids. These very large, carnivorous, shallow-water fish would have looked and behaved much like alligators, or giant salamanders. They looked like tetrapods in many respects, except that they still had fins. Until recently, elpistostegids were known only from small fragments of fossils that were poorly preserved, so it has been hard to get a rounded picture of what they were like. In the past couple of years, several discoveries from northern Canada have changed all that. In 2006, Edward Daeschler and his colleagues described spectacularly well- preserved fossils of an elpistostegid known as Tiktaalik. This new fossil allow us to build up a good picture of an aquatic predator with distinct similarities to tetrapods from its flexible neck, to its very limblike fin structure. Elpistostegid: This is a computer rending that scientists were able to produce from the Tktaalik fossil of an Elpistostegid 10

11 1. What is a tetrapod in your own words? Also provide an example of a tetrapod that is not mentioned in the text. 2. How did scientists theory about the evolution of tetrapods change with the finding of the Acanthostega fossil? What evidence did they find that refuted their initial hypothesis? 3. Tetrapods such as humans, cows, and lizards are all extremely different organisms. However, according to the fossil record all they share a common ancestor. In other words, all tetrapods evolved from the same ancient organism. What is the common ancestor of humans, cows, and lizards according to the text? 11

13 Science 8 Name: SKILL SNAPSHOT Date: E.3: Examining Evidence Homeroom: Quick Notes: Like A Scholar? Yes No Redo? Yes No 1. Scientists call the fossil pictured a transitional fossil because it has characteristics of both dinosaurs and birds. How does this fossil serve as evidence for the theory of evolution? 13

14 Directions: Answer each multiple choice question. Once you have selected the best answer, justify your reasoning in the text box. Your justification needs to be in complete sentences and use evidence from today s packet. 2. Several species of extinct giant tortoise lived on different islands in the Indian Ocean. One species is still alive on Aldabra Island. The shells and skins of the extinct tortoises are in museums and can be studied. What is the most accurate way to find out how closely related the living one is to the extinct one? A. Search the history records of what the extinct tortoises look like. B. Compare the bones and shells of the extinct tortoises to each other. C. Measure the distance between Aldabra and the other islands. D. Compare the DNA of all the tortoise species, extinct and living. 3. Fossils of the Coelacanth fish occur in the fossil record from 410 to 65 million years ago. The lack of more recent fossils led scientist to conclude that the fish went extinct along with the dinosaurs. In 1983, a fisherman caught a living Coelacanth. More than 200 of them have been caught on the deep reefs in the Indian Ocean. This fish has been called a living fossil because its body plans in nearly identical to the 400 million year old fossils. This structural similarity supports which statement? A. The environment of the deep sea has changed little over millions of years. B. The amount of salt in the deep sea has varied greatly over millions of years. C. The oceans have completely dried up multiple times during the past 400 million years. D. The oceans have been continuously repopulated by freshwater fish species over millions of years. 14
