Evolution Cornell Notes Pick Up: Have out: Blank Paper Homework: Stamp for Chapter 7 Notes Monday, 10/28 Evolution Cornell Noted due Monday • Take a blank sheet of paper out. • Title it Hydraulic Fracking Perspective • Click through the PowerPoint, play the youtube links on each of the slides and watch the video’s, take notes. Shale Rock – where the gas/oil is. The Oil/Gas is in Black. How do we get it? The effects on the habitat. Copy this down. Two sides of Fracking Issue Environmentalist • Destroy the environment by cause air, water pollution. • Loss of habitat for local animals. • Aesthetically ugly • More traffic more noise. Industrial/Economic • Makes jobs • Makes money for the federal, state, local government. • Be energy self sufficient and not need to import from overseas. DUE in 20 minutes: On your paper pick one of these perspectives and write a 1-2 paragraph persuasive argument about why they are correct. Turn in when done (20 minutes) 8.5 to 8.9 Evolution and Human Impacts APES Learning Goal: •I can explain the effects of fracking on the environment. I can explain the effects of fracking on the environment. Linear Evolution – a common misconception Evolution is similar to a tree with branches Figure 8-11 Figure 8-12 Species – live, fertile offspring Evolution: genetic differences of successive populations – change over time 2.Macroevolution – long term, largescale changes. Ex: land mammals to whales. How does this happen? Microevolution - small genetic changes in population that happen over a short time frame • Mutations can creates genetic diversity. Can be harmless, lethal, beneficial, random / unpredictable and a rare source of new traits Reproductive Isolation Gene pool - All of the genes in a population genetic variation – different fur thickness Natural selection – beneficial adaptations survive End Result Evolution Galapagos Tortoise – Different Islands different shell shapes? Why? Types of Natural Selection 1. Directional Selection – a variation is beneficial and the gene pool shifts towards one extreme. Stabilizing Selection -the extremes are not well adapted and the average variations are favored. Example: ►Speckled peppered moths Disruptive Selection – both extremes are Example: advantageous ►Darwin’s finches on Galapagos Islan and being average is not. Coevolution The flower produces nectar that provides the perfect nutrition for the bird, and exists in colors that the bird sees best. Meanwhile the bird's beak is perfectly shaped to drink from the flowers. The flower provides food for the bird, and the bird, by drinking from several different flowers spread pollen between flowers. A tale of two Squirrels divergent evolution – one species becomes two Which Types of Isolation? •Geographic – Colorado River physically separates them •Reproductive – one population can’t breed with the other. So. What does Survival of the Fittest Mean? • The ability to SURVIVE AND REPRODUCE is th e most fit. • NOT (always)THE STRONGEST – could be smallest, largest, fastest, slowest, etc. APES Learning Goal: I can explain ecosystem Diversity Major Sources of Change • Continental Drift • Rapid/Gradual Climate Change • Human influenced changes – ex. Loss of biodiversity from deforestation. Extinction – the loss of a species • Background extinction rate – the rate at which species go extinct under “typical” slowly changing local conditions. • Mass Extinction - Due to a major event large numbers of species die out quickly. – 5 mass extinctions in Earth’s history – We are the cause of the 6th Mass Extinctions When the last individual of a race of living things breathes no mor another Heaven and another Earth must pass before such a one can be again.” --William BeeBe Adaptive Radiation – Dinosaurs going extinct left a lot of empty niches that were filled by mammals. . Mass Extinction of Dinosaurs APES Learning Goal: I can explain ecosystem Diversity Closure Question PLEASE ANSWER THE QUESTION ON THE NEXT SLIDE AND TURN IN. A question about a pet tarantula. • I got him about 5 months ago in June. He's most definitely a land tarantula and ever since I got him a home to live in (a terrarium with smooth sides) he has always been trying to climb on the walls but his feet just slip off the walls. On Tuesday I came home and all of his legs were on the wall but one was still holding him up from the ground. Today, Thursday, I got home from school and he was crawling on the top of the wall/ceiling and it seems as if his feet now have suction cup or sticky bottoms that allow him to crawl on the walls. Do you think it's possible that my tarantula could have adapted this much in less than 5 months? I was really curious and it couldn't wait until Monday.
