Chapter 20 PHYLOGENY Introduction to Phylogeny Phylogeny is the evolutionary history of a species or group of related species Discipline of systematics classifies organisms and determines their evolutionary relationships Taxonomy is the ordered division and naming of organisms Cladistics Cladistics classifies organisms by common descent A clade is a group of species that includes an ancestor and all its descendents Using Derived Characters Characters can be used to infer evolutionary relationships. Molecular Clocks Molecular clocks use mutation data in related genes from different species Number of nucleotide changes is assumed to be proportional to the time since last common ancestry ie. Few changes = little time passed; many changes = lots of time passed

Introduction: Themes in the Study of Life Chapter 1 Overview: Inquiring About Life An organism?s adaptations to its environment are the result of evolution For example, the ghost plant is adapted to conserving water; this helps it to survive in the crevices of rock walls Evolution is the process of change that has transformed life on Earth ? 2011 Pearson Education, Inc. Figure 1.2 Biology is the scientific study of life Biologists ask questions such as How does a single cell develop into an organism? How does the human mind work? How do living things interact in communities? Life defies a simple, one-sentence definition Life is recognized by what living things do ? 2011 Pearson Education, Inc. Figure 1.3 Order Evolutionary adaptation Response to the environment

Campbell's Biology, 9e (Reece et al.) Chapter 1 Introduction: Themes in the Study of Life This introductory chapter explores the basic themes and concepts of biology, with emphasis on the core theme of evolution. It also introduces students to the thinking of scientists. Questions are therefore general; however, an effort has been made to include some from each skill level. As in the rest of this test bank, questions that feature art or those for which several questions follow upon some data or a scenario are placed together at the end of the chapter. Multiple-Choice Questions 1) A localized group of organisms that belong to the same species is called a A) biosystem. B) community. C) population. D) ecosystem. E) family. Answer: C Topic: Concept 1.1

0 1 Introduction: Evolution and the Foundations of Biology Overview: Inquiring About Life An organism?s adaptations to its environment are the result of evolution For example, a beach mouse?s light, dappled fur acts as camouflage, allowing the mouse to blend into its surroundings Inland mice of the same species are darker in color, matching their surroundings Evolution is the process of change that has transformed life on Earth Figure 1.1 Figure 1.2 Biology is the scientific study of life Biologists ask questions such as How does a single cell develop into an organism? How does the human mind work? How do different forms of life in a forest interact? Concept 1.1: Studying the diverse forms of life reveals common themes

Who is more closely related to salamanders? A. Lungfish B. Humans 3 Trees are hypotheses 4 Jetz et al. 2012. Nature 491: 444-448 But how do we construct trees? 5 Similar species are likely related Taxa that are more similar are likely more closely related than less similar species Morphology DNA sequence Behaviour ? 6 Similarity due to shared ancestry produces homology 7
