Evidence of Evolution and Mechanisms of Change
The students should be able to:
- explain how continuous investigations by multiple scientists and new scientific information has influenced theories over time
- describe scientific explanations of the origin of life on Earth, such as those posed by: Oparin, Miller and Urey, Margulis, Fox, and Pasteur
- identify conditions contributing to the origin of life on Earth, such as: organic molecule synthesis, Earth’s early atmosphere, primordial soup
- explain why the scientific theory of evolution is supported through various disciplines and evidence, such as: fossil record, comparative anatomy, comparative embryology, biogeography, molecular biology, and observed changes over time
- identify basic trends in hominid evolution from early ancestors, from six million years ago to present, including: brain size, jaw size, language, and manufacturing of tools
- describe the conditions required for natural selection that result in differential reproductive success, including: overproduction of offspring, inherited variation, and the struggle to survive
- explain how biological diversity is increased by the emergence of new species and decreased by natural selection
- discuss mechanisms of change other than natural selection, such as: genetic drift, gene flow, and non‐random mating
- explain how mutation and genetic recombination increases genetic variation
