Mendel's Genetics ? Hybridized domesticated horses For thousands of years farmers and herders have been selectively breeding their plants and animals to produce more useful?hybrids?. ? It was somewhat of a hit or miss process since the actual mechanisms governing inheritance were unknown.? Knowledge of these genetic mechanisms finally came as a result of careful laboratory breeding experiments carried out over the last century and a half. ? ? Gregor Mendel???? 1822-1884???

Chapter 1 Biology: The Study of Life I. What is Biology? A. The Science of Biology Biology: the study of life Organism: anything that possess all the characteristics of life B. Characteristics of Living Things All living things Have an orderly structure Produce offspring Grow and develop Adjust to changes in the environment 1. Living things are organized Organization: orderly structure; cells, tissues, organs, organ systems 2. Living things make more living things Reproduction: production of offspring Species: a group of organisms that can interbreed and produce fertile offspring in nature 3. Living things change during their lives Growth: an increase in the amount of living material and the formation of new structures

Name Period Chapter 1: Introduction: Themes in the Study of Life Begin your study of biology this year by reading Chapter 1. It will serve as a reminder about biological concepts that you may have learned in an earlier course and give you an overview of what you will study this year. In the overview, Figure 1.3 recalls many of the properties of life. Label the seven properties illustrated here, and give a different example of each. Concept 1.1 The themes of this book make connections across different areas of biology What are emergent properties? Give two examples. Life is organized on many scales. Figure 1.4 zooms you in from viewing Earth from space all the way to the level of molecules. As you study this figure, write in a brief definition of each level.

Ch 22: Descent with Modification Charles Darwin published On the Origin of Species by Means of Natural Selection (November 24, 1859) Origin of Species- focused biologists? attention on the great diversity of organisms a. Origins and relationships, similarities and differences, geographic distribution, adaptations to surrounding environments b. Presented evidence that the many species of organisms presently inhabiting Earth are descendants of ancestral species that were different from the modern species c. Proposed a mechanism for this evolutionary process Natural Selection Natural Selection- population can change over generations if individuals that possess certain heritable traits leave more offspring than other individuals

Big Idea 1: The process of evolution drives the diversity and unity of life Enduring Understanding 1.A- Change in the genetic makeup of a population over time is evolution Essential knowledge 1.A.1: Natural selection is a major mechanism of evolution According to Darwin's theory of natural selection, competition for limited resources results in differential survival. Individuals with more favorable phenotypes are more likely to survive and produce more offspring thus passing traits to subsequent generation. (Fitness) Evolutionary fitness is measured by reproductive success Genetic variation and mutation play roles in natural selection. A diverse gene pool is important for the survival of a species in a changing environment.

Biology 160 Study Guide #5 1. Be able to write the basic reaction that describes cellular respiration 2. What are the three main stages of cellular respiration? Be able to say what goes in and what comes out of each of these stages. 3. What is chemiosmosis (be able to describe the process)? 4. What is the form of energy actually used by your body? 5. What happens if you don?t have oxygen? 6. What is fermentation? 7. Be able to describe how the three main forms of nutrition are used for energy or made by the reverse of these cycles. 8. What is the basic mechanism responsible for global warming? 9. What are the central themes in the theory of natural selection? 10. How has the fossil record been preserved?

Erasmus Darwin Charles Darwin 18591874 Voyage of the HMS Beagle On the Origin of Species? ? Descent With Modification ? By means of Natural Selection Support for Descent with Modification ? Biogeography ? Fossil Record ? Molecular Biology, Biochemistry, Cell Biology ? Comparative Anatomy ?Biogeography ? Biogeography, the geographic distribution of species ? Darwin noted that Gal?pagos animals resembled species of the South American mainland more than animals on similar but distant islands The study of fossils provides strong evidence for evolution

Chapter 26 ? Phylogeny and the Tree of Life Overview: Investigating the Tree of Life Process of evolution ? the evolutionary mechanisms (from Unit 4) Pattern of Evolution ? observations of evolution?s products over time. (focus of this chapter) Phylogeny ? The evolutionary history of a species or group of species. Systematics - A discipline focues on classifying organisms and determining their evolutionary relationships. Systematics uses data from fossils to molecules and genes to infer evolutionary relationships. (figure 26.2) 26.1 Phylogenies show evolutionary relationships Taxonomy ? the scientific discipline of how organisms are named and classified. A. Binomial Nomeclature (Instituted by Linnaeus) Binomial: The two part format of the scientific name
