IB Assessment Statements and Class Objectives 5.1.U2 The fossil record provides evidence for evolution. Define strata and paleontology. Explain three pieces of evidence that fossils provide that evolution has occurred. 5.1.U3 Selective breeding of domesticated animals shows that artificial selection can cause evolution.

Biology guide 1 Introduction Purpose of this document This publication is intended to guide the planning, teaching and assessment of the subject in schools. March 2017 POLYDACTYL Y IN DEVELOPMENT, INHERIT ANCE, AND EVOLUTION 31. Heredity. Heredity analysis (x) x x x x x x x x x. Maternal inheritance x. Maternal inheritance to doughter or paternal to Tetrapod pentadactyl limbs may be analyzed and compared to ascertain what environmental and evolutionary pressures led to morphological changes (in other words: how an animal's environment and use of its limbs affected their shape), as well as how different species are related. Flying (forelimb) bird, bat Swimming (forelimb) 17. Describe how the pentadactyl limb provides evidence for evolution. Give two example s in your answer and for each explain how their limbs are adapted to their function. 18. Doctors are now prescribing fewer antibiotics to reduce th e evolution of antibiotic resistant bacteria. Describe the process of evolution of an tibiotic bacteria. 19. What methods of questions of lessons, they also religious interpretation that the morphological and feeding in the scientific criteria specified above for biology evolution worksheet answers to. Homologous structures: vertebrate embryos and the pentadactyl limb. Worksheet 3.1: Vertebrate limbs Students compare different vertebrate pentadactyl limbs and speculate on how closely related they are to each other. Activity Book pp. 36-38 Artificial selection Define artificial selection/selective breeding. Using budgerigars as an example, explain how selection and breeding of mutants over many Limb (biology): An extremity or appendage that is distinct from the head and trunk; an arm, leg, flipper or wing. (from Old-English lim, 'branch, part, or member,' also Latin limbus, 'border or edge') Many pentadactyl tetrapods use limbs for locomotion, such as walking, running, flying, climbing, digging and swimming. developed the idea of evolution by natural selection. Describe some of the evidence that Darwin and Wallace used to support their idea. Explain the impact of the idea of evolution by natural selection on modern biology. and where it is found. Recall what is meant by the pentadactyl limb, Name 2 characteristics for the evolution of reptiles to mammals. Live birth, 4 chambered heart, and skin/fur. found and why? In what era were the dinosaurs abundant? Jurassic - Mesozoic . The set rate at which half of the . Give the example of homologous structures. Pentadactyl limb. What characteristic of the pentadactyl limb is similar Evolution is the change in allelic frequency in a gene pool of a population over time, as a result of natural selection, genetic drift, gene flow, and mutation pressure. 5.1.U
