Zoe Collins Mrs. G AP Biology 30 March 2014 Pedigree Lab Introduction: Gregor Mendel laid the foundation for our knowledge on genetics, and as time went one scientists continued to confirm and extend Mendel?s ideas. Discoveries on subjects such as DNA structure, mitosis and meioses all explain Mendel?s hypotheses. Mendel demonstrated that genes on different chromosomes, or unlinked genes, are inherited separately under the idea of independent assortment. But due to linked genes gametes are often produced with different combinations of alleles that are different then those of the parents.

Chapter 23: The Evolution of Populations This chapter begins with the idea that we focused on as we closed the last chapter: Individuals do not evolve! Populations evolve. The Overview looks at the work of Peter and Rosemary Grant with Gal?pagos finches to illustrate this point, and the rest of the chapter examines the change in populations over time. As in the last chapter, first read each concept to get the big picture and then go back to work on the details presented by our questions. Don?t lose sight of the conceptual understanding by getting lost in the details! Overview The Smallest Unit of Evolution ?One misconception is that organisms evolve, in the Darwinian sense, during their lifetimes

Chapter 12 Sustaining Biodiversity: The Species Approach Core Case Study: The Passenger Pigeon - Gone Forever Once the most numerous bird on earth. In 1858, Passenger Pigeon hunting became a big business. By 1900 they became extinct from over-harvest and habitat loss. Figure 11-1 SPECIES EXTINCTION Species can become extinct: Locally: A species is no longer found in an area it once inhabited but is still found elsewhere in the world. Ecologically: Occurs when so few members of a species are left they no longer play its ecological role. Globally (biologically): Species is no longer found on the earth. Global Extinction Some animals have become prematurely extinct because of human activities. Figure 11-2 Endangered and Threatened Species: Ecological Smoke Alarms

Chapter 4: Biodiversity and Evolution 4-1 What is biodiversity and why is it important? Biodiversity is a Crucial Part of the Earth?s Natural Capital Biological Diversity (Biodiversity) is the variety of the earth?s species. The genes they contain, the ecosystem in which they live, and the ecosystem processes such as energy flow nutrient cycling that sustain all life. Genetic Diversity enables life on earth to adapt and survive dramatic environmental changes. Ecosystem diversity are storehouses of genetic and species diversity Functional diversity is the variety of processes such as matter cycling and energy flow taking place within ecosystems. 4-2 Where Do Species Come From?

background extinction During most of the 3.56 billion years that life has existed on the earth, there has been a continuous, low level of extinction of species known as background extinction. endangered species has so few individual survivors that the species could soon become extinct over all or most of its natural range (the area in which it is normally found). extinction rate expressed as a percentage or number of species that go extinct within a certain time period such as a year. HIPPCO Habitat destruction, degradation, and fragmentation; Invasive (nonnative) species; Population and resource use growth (too many people consuming too many resources); Pollution; Climate change; and Overexploitation.
