Question;Assignment:Please remember that all assignments are due early in the due date period but must be submitted no later than the last day of that period (see the posted Assignment Schedule).How Populations EvolveLesson 10: Chapter 13Quiz 8Lab 8 (What Causes a Species to ChangeIn This posting:1. Lesson 10 Competencies and Objectives2. Teaching Element, Materials for Lab 8 and web links3. Assignment Posting4. Exam Information5. Looking Ahead to Lab 9 (Period 6a Classification)Lesson 10 Objectives: (These are specific objectives that must be met, as outlined in the online lesson.Please focus on these, rather than purely on the chapter material because the exams are based off ofthese. In other words, the exam questions will test whether you meet and understand these particularpoints. Therefore I cannot stress enough how important they are to your success in the class.)1. Describe the contributions of Lamarck, Darwin, Lyell, and Wallace to the theory of evolution.2. Explain the observations and deductions that Darwin generated to account for natural selection.3. Define the term natural selection.4. Explain the theory behind how evolution occurs, including the terms natural selection, fitness,adaptations, traits, and behavior.5. Provide direct and indirect evidence for the theory of evolution (e.g., the fossil record, biogeography,comparative anatomy, comparative embryology, and molecular biology).6. Explain the significance in studying homologous and vestigial structures.7. Distinguish between the following concepts: genetic drift versus gene flow, the founder effect versusbottleneck effect, directional, disruptive and stabilizing selection, and sexual versus natural selection.8. Analyze both the historical and current debate over the theory of evolution.9. Compare early methods of biological classification to modern classification techniques.Teaching ElementThis teaching element is somewhat different from those written for the past lessons.It is well known that Charles Darwin visited an archipelago of islands 600 miles off the coast of Ecuador. He left England aboard theH.M.S. Beagle in 1831 for a 5 year journey. He first landed on San Cristobal Island. The famous book the Origin of Species waspublished in 1876.The animals found on the Galapagos Islands, visited by Charles Darwin are not found anywhere else in the world. The government ofEcuador has done a great job to preserve the islands and to prevent removal of any animals. Therefore you will see very few of these animalsin zoos throughout the world. These animals roam free, and visitors are have the privilege to walk among them. They have no fear ofhumans, and there are very few predators consequently they live a very stress free life. A rule of islands is that you must never approach ortry to pet these animals. If they are in your path you must stop and wait for them to pass or walk around them. Visits to the islands require1 certified guide for every 16 visitors.In this teaching element I want to show you some photos that I took while re?tracing the footsteps of Charles Darwin on these islands. Iwill provide captions where possible.Juvenile Galapagos Sea Lion ? San Cristobal IslandGalapagos Swallow Tail GullYellow Crowned Night Heron (more below)Male Frigate Bird, the red pouch is an attraction to females during mating season.Nasca or Masked Boobie, called this because it appears to be wearing a mask (see below)The juvenile red footed Boobie, notice the characteristic red feet.A very rare bird that makes it?s home on the Galapagos Islands, the Short Eared OwlSally Light Foot Crab.Marine Iguana be careful where you walk these blend into the lava.The Flightless Cormorant (see below) This bird is also featured in a segment of the movie Master andCommander which has several scenes that fictionalize Darwin?s visit to the islands.Blue Footed Boobies in a mating ritual.Check these out as well: It is about the Galapagos Concervancy website which is about cruising the Islands aswell as providing information on the wildlife found there. Read the article about the Pinta Tortoise. Dawkins? video titled The Genius Of Charles Darwin ? Part 1 ? Life, Darwin & Everything is worth watching. Do not beoffended by Dawkin?s proclamation at the beginning that he does not believe in G?d. 8 EvolutionFrom the Lab Kit you should have the following materials for Lab 8 Evolution?Fabric?Forceps?Pieces of colored foam (10 different colors)?Punch template?Paper hole punchStudent supplied materials for lab 8 Evolution include:?Pencil?Cup (8 oz)Announcements: Regarding Online Exams The second exam will cover lessons 7 through 12 Period 6b They may only be opened 1 time, do not click on the link for the exam until you are ready tocomplete it or you will lose your attempt and receive no credit for the exam.The exams are the most important events of the course. As stated in the syllabus, studentsmust earn at least a 60% average on the exams in order to receive a passing grade in theclass (irrespective of the overall class average). For example, if a student earns a 50% on thefirst exam, a 70% on the second exam, and a 54% on the third exam, a combined average of 58%would be earned and therefore the student would not pass the class.If the exams are not taken on time, there will be a 10% penalty deducted from the final scoreif taken up to four days late ? and no credit thereafter.Each exam is timed and password protected. The password will be provided to you by yourinstructor prior to the exam. The exam consists of 100 questions and is broken into two sections,each containing 50 questions. You will have 40 minutes to complete each part (40 minutes for part1 and 40 minutes for part 2). There is a timer in the upper right hand corner of the exam to help youkeep track of your progress.Please make sure you have answered all questions in Part 1 prior to clicking on the submit button.Once a part has been submitted, you will not be able to return to that section. Immediately followingsubmission of Part 1, return to the lesson for the link to access Part 2 of the exam.BOTH parts of the online exam MUST be completed in one sitting. For example, students arenot permitted to complete Part 1 of Exam 1 on Monday, and then return to the assessment andcomplete Part 2 of Exam 1 on Friday.Any student found completing the online exams in multiple sittings without department approval, willlose credit.In Period 6a you will be doing Lab 9 Classification.1.There are no lab materials needed for lab nine.2. You might want to do a web search and take a look at examples of dichotomous classification keys. It may help you to workthrough the lab and understand the keys you will be working with.3. I suggest you read through the lab questions before you read through the lab. In this way you can have some idea of what tolook for that might provide an answer to a particular question.4. If there is anything I can help with please feel free to ask.Tutoring ServicesRio offers tutoring services where you can get help studying for tests, learn study techniques, and get help with concepts. They can also help with test taking strategies. With the upcoming exams drawing near, you may find it helpful to work with the tutors if you do experience test anxiety. There is online or in-person (at the Tempe campus) tutoring available. This service is free to you, so if you need some extra support in your studies in this course or in future Rio biology courses, please take advantage of this opportunity. See their webpage for information: Tips for SuccessNotebook:Keep a course notebook where you can keep your notes over what you learn in the online lessons and asyou read the textbook. It will be easier to study if you have everything in one place.Draw Diagrams:As you read the book and take notes, you might find it helpful to draw the diagrams that are included inwhat you are learning. Sometimes you might want to copy the diagrams from the book (like perhaps whenyou are learning about the Krebs cycle) or other times you might want to create your own diagrams basedon what you are reading. This can help give a visual representation of how the concepts are related orconnected to one another.Textbook:In the textbook, there are review questions at the end of each chapter. Make sure that you can answer allof the questions after you read each chapter. If not, go back and review where necessary.Create a Weekly Schedule for Yourself:Please remember that in order to be successful in this course you should be spending at least 12-15 hourseach week studying biology. Some students find it helpful to create a schedule each week to help plantheir time and organize their studies. I would recommend looking at everything that you do each week andthen creating a daily schedule to help you stay on task.Complete all Assignments on Time:Please don?t wait until the last day to start your assignments - start early in the week so that you have time to handle any unforeseen problems and to get all the materials needed for
