Adaptive Evolution is driven by natural selection. Natural selection is not "survival of the fittest," but rather "reproduction of the fittest." Evolution can occur at many different speeds based on the strength of the selection driving it. These types of selection can result in directional, stabilizing, and disruptive outcomes. They can be driven by frequency-dependent selection and sexual selection, in addition to more standard types of ...more
(April 14, 2010) Robert Sapolsky continues his series addressing the link between behavior and genetics. He covers the complex endeavor of gene isolation and variability and heritability and wrongly eliminated environmental influences in heritability tests -- finding that genes and environment are infinitely interconnected and co-dependent on each other.
Environmental Politics and Law (EVST 255) The change from smaller, more diverse farms to larger single-crop farms in the US has led to greater reliance on pesticides for pest management. Other changes as the US food system becomes more commercialized include: increased use of additives, higher food prices, more water and energy consumption for agriculture, and more pesticide residues entering food through processing. Pesticides have al...more
This course is designed to serve as a first course in an undergraduate electrical engineering (EE), or electrical engineering and computer science (EECS) curriculum. The course introduces the fundamentals of the lumped circuit abstraction. Topics covered include: resistive elements and networks; independent and dependent sources; switches and MOS transistors; digital abstraction; amplifiers; energy storage elements; dynamics of first- an...more
Thompson stresses the need for customer diversity. Software companies that were dependent on Fortune 1000 companies for their business suffered when their niche clients also suffered in the economic downturn. If a company is to survive challenging economic times, companies must have a diverse customer base, he says. Symantec brings stability to its business by serving individual customers as well as the largest governments and corporations...more
Earth & Space Science 15: Introduction to Oceanography is a class that provides a general introduction to geological, physical, chemical, and biological processes and history of Earth's global oceanic system. Edwin Schauble is an Associate Professor from UCLAs Department of Geochemistry and Astrobiology. His current area of study and collaboration include species-dependent isotopic signatures in dissolved iron, spectroscopic signatures an...more
Linear Independence and Linear Dependence, Ex 1. In this video, I explore the idea of what it means for a set of vectors to be linearly independent or dependent. I then work an example showing that a set of vectors is linearly dependent.
Lesson 5. Making a drawing that is dependent for its success on mathematical accuracy.
Details on the light-dependent reactions of photosynthesis.
