Genetics controls evolution. There are four major genetic systems, which are combinations of sexual/asexual and haploid/diploid. In all genetic systems, adaptive genetic change tends to start out slow, accelerate in the middle, and occur slowly at the end. Asexual haploids can change the fastest, while sexual diploids usually change the slowest. Gene frequencies in large populations only change if the population undergoes selection.

Banks, which were first created in primitive form by goldsmiths hundreds of years ago, have evolved into central economic institutions that manage the allocation of resources, channel information about productive activities, and offer the public convenient investment vehicles. Although there are several types of banking institutions, including credit unions and Saving and Loan Associations, commercial banks are the largest and most importa...more

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

Neutral evolution occurs when genes do not experience natural selection because they have no effect on reproductive success. Neutrality arises when mutations in an organism's genotype cause no change in its phenotype, or when changes in the genotype bring about changes in the phenotype that do not affect reproductive success. Because neutral genes do not change in any particular direction over time and simply "drift," thanks in part to the...more

Originally, altruism and self-sacrifice were thought to be incompatible with natural selection, even by Darwin. Now we have several explanations for how altruism can increase an individual's fitness. One is kin selection, or the idea that helping relatives can help increase one's genes in the population. Another involves ecological constraints and punishments. Here, individuals contribute to the group and wait their turn to reproduce.

Insurance provides significant risk management to a broad public, and is an essential tool for promoting human welfare. By pooling large numbers of independent or low-correlated risks, insurance providers can minimize overall risk. The risk management is tailored to individual circumstances and reflects centuries of insurance industry experience with real risks and with moral hazard and selection bias issues. Probability theory and statist...more

Mutations are the origin of genetic diversity. Mutations introduce new traits, while selection eliminates most of the reproductively unsuccessful traits. Sexual recombination of alleles can also account for much of the genetic diversity in sexual species. In some instances, population size can affect diversity and rates of evolution and fixation, but in other cases population size does not matter.

Psychology 116: Neuroscience Lab is a laboratory experience exploring various topics in behavioral neuroscience. Dr. William Grisham is a Professor from UCLAs Department of Physiological Science. Since July of 1996, Dr. Grisham coordinated and taught upper division laboratories in Interdepartmental Program in Neuroscience and Biopsychology majors for UCLA. Furthermore, he participated in selection and development of laboratory exercises...more

Eisenhardt discusses the ideal markets for start-ups. She classifies them into emergent, growth and mature. Emergent markets are typically small and undefined, growth markets are between $30M-$50M with a high growth rate and mature markets are > $100M. She suggests that the ideal market for a company to start in is a growth market.

The Global Fund for Women (GFW) is overwhelmed with requests for grants-3,000 every year, in many languages, says Ramdas. International advisors give feedback on priorities for social areas in their communities. GFW also have a basic set of criteria -- is it a group of women instead of an individual, do they have a clear articulation of how they will challenge women's positions within that society? GFW doesn't give a grant until they have ...more
