1 Mr. Saenz Biology Dept North Pitt High School FYI Charles Darwin Charles Darwin came from a family of doctors, and he almost became one, too. Both his father and grandfather were doctors, and they urged him to follow in their footsteps. Charles started out in medical school but soon found that he did not like it. He then went to theological school to study to become a minister. Darwin had always been interested in nature, so he also took courses in biology and geology. These courses were the extent of his formal training as a naturalist when he accepted a job on the HMS Beagle. Darwin was not the most qualified applicant, but he was hired anyway because the captain, Robert Fitz Roy, thought Darwin would make a good companion for the five-year voyage. Before Darwin came up with his theory he had some ideas from earlier scientists. James Hutton and Charles Lyell: They proposed that the Earth has changed gradually over time. Darwin took this idea and expanded on it Life has changed gradually over time!!! Jean-Baptiste Lamarck (1809): French naturalist, who first recognized that living things have changed over time and that all species were descended from other species. He proposed that by selective use or disuse of organs, organisms acquired or lost certain traits during their lifetime. These traits could then be passed on to their offspring. Over time, this process led to change in a species Theory Status: Disproven Lamarck s Theory 1

2 Thomas Malthus (1798): He reasoned that if the human population continued to grow unchecked, sooner or later there would be insufficient basic needs for everyone. Main reason why populations cannot grow exponentially forever (J-curve) What scientific explanation can account for the diversity of life? Evolution Who was Charles Darwin? The founder of the modern theory of evolution was born on February 12, 1809 What was his job? Naturalist (collect, study and label specimens) Where did he do a lot of his onsite research? Galapagos Island (South America) What was the name of the boat? HMS Beagle What happened during his travels? He saw lots of biological diversity Ex. In a forest in Brazil he collected 68 different species of beetles-despite the fact he was not even looking for them. He noticed that even though Argentina and Australia have similar grassland ecosystems, the animals inhabiting those lands were different from each other. He collected fossil remains of ancient organisms which resembled organisms of today. Found several brown birds w/ different shaped beaks Found some mockingbirds which were different from each other What did he later learn from his travels? The brown birds w/ different shaped beaks were actually the same species The mockingbirds were actually different species What did he envision? a theory about the origin of adaptation, complexity, and diversity among Earth s living creatures Many found his idea brilliant, while others strongly opposed it WHY? Back in those days People believed that the Earth and all its forms of life had been created only a few thousand years ago. Since that original creation, they concluded, neither the planet nor its living species had changed. Many religions still do this day. Who was this theory? The theory of evolution by natural selection What is natural selection? Remember, since growth does not occur exponentially forever species will struggle to exist! small, random, heritable differences among individuals result in different chances of survival and reproduction This is called fitness success for some, death without offspring for others this leads to changes in shape, size, strength, color, biochemistry and behavior among the descendants 2

3 How does it work? since less successful competitors produce fewer offspring, those weaker traits disappear the stronger/better traits tend to increase gradually throughout the population What is another phrase for this? Survival of the Fittest What is artificial selection then? Same as natural selection, just instead of nature picking the strong traits, man does What is the name of the book he wrote? The Origin of the Species by Natural Selection What evidence does he have for this? 1- Biogeography 2- Paleontology 3- Embryology 4- Morphology Biogeography Biogeography The study of the geographical distribution of living creatures Species now living on different continents had each descended from different ancestors. Since some animals on each continent were living under similar conditions, they were exposed to similar pressures of natural selection. Because of these similar selection pressures, different animals ended up evolving certain striking features If you put two different animals in similar environments, then the strong traits in one area for an animal will be the same strong traits for the other area for the other animal. This can lead to two different looking animals evolving to look the same but they are still different species. Beaver NORTH AMERICA Muskrat Capybara SOUTH AMERICA Coypu Beaver Muskrat Beaver and Muskrat Coypu Capybara Coypu and Capybara Paleontology Hundreds of transitional fossils that document various intermediate stages in the evolution of modern species from organisms that are now extinct. Fossils sometimes can tell what was alive at one time and how long ago it was Gaps remain a.k.a. The Fossil Record Embryology That many different organisms have many similarities when comparing their early stages of life. 3

4 Morphology The number of shared characteristics between any one species and another indicates how recently those two species have diverged from a shared lineage In other words The more different species look alike (or have in common) indicates how closely related they are. Morphology Homologous Structures Structures in different species which superficially look different but are quite similar in their foundation. Turtle Alligator Bird Mammal Ancient lobe-finned fish Morphology Analogous Structures no similarity in structure, but similarity in fxn Vestigial Structures structures which now have no fxn, but once did vestigial structures stand as left behind evidence of the evolutionary history of a lineage Traits have variation. Some variations of a trait increase or decrease an organism s chance of survival in an area. Variations of a trait are controlled by alleles (genes) and can be inherited. Therefore, the frequency of an allele (gene) for a trait in a populations gene pool can change due to natural selection. Significant changes in the gene pool can lead to the evolution of a new species over time. Variation in Traits These butterfly live in different areas of North America Stabilizing Selection average organisms have the survival advantage in an environment Despite their slight variations, they can interbreed to produce fertile offspring 4

5 Directional Selection one extreme trait for a species has the advantage for survival but another extreme does not Disruptive Selection either extreme trait for a species has the advantage for survival Patterns of Evolution Types: 1. Macroevolution a. b. c. d. e. f. Extinction Divergent Evolution Convergent Evolution Coevolution Punctuated Equilibrium Changes in Developmental Genes Macroevolution Large scale evolutionary patterns that occur over a long period of time. 2. Microevolution Extinction Divergent Evolution Usually, it occurs due to reasons of natural selection (Darwin). Sometimes events cause wipe outs of entire ecosystems leading to mass extinctions. When an ancestral species evolves into an array of species to fit a variety of habits. If you place 2 similar looking species in different environments over time they will become more different in their appearance due to the differences in the traits needed to survive. This is how one species can evolve into many different species. Another name for this is ADAPTIVE RADIATION Ex. dinosaurs Mass extinctions can result in a burst of evolution that produces many new species. 5

6 Divergent Evolution Convergent Evolution When different looking species evolve similar traits due to living in similar environments. If you place 2 different looking species in similar environments over time they will become more similar in their appearance due to the similarity in the traits needed to survive. Ex. Beaver, Muskrat, Cupybara Ex. Shark, penguin, dolphin Coevolution How two species evolve to each others needs over time Ex. The moth with the long tongue due to the flowers petals Changes in Developmental Genes Changes in the activation of certain genes can lead to major evolutionary transformations. Ex. Ancient insect wings compared to modern insect wings. Due to wingless gene being turned on at an insects body segment. Ex. Long legs/short legs; same for fingers Punctuated Equilibrium Rapid evolution in a species after long periods of no change (equilibrium) Could indicate that evolution is not always slow and steady like Darwin said Gradualism evolution at a slow and steady rate. Microevolution Evolution within a single population or species. Tends to happen quicker Ex. Bacteria becoming resistant to antibiotics. Ex. Insects and weeds becoming resistant to insecticides and herbicides. Ex. HIV becomes resistant to AZT 6
