Here we have some highlights of how the natural selection works and some of the evolutionary forces that drive evolution: The natural selection operates in base of the difference between de reproductive successes of the individuals. The genes of the most successful individuals (the ones that reproduces more) appears more in the next generation. If an individual cannot survive it will not be able to reproduce. Because of that natural selection is NOT RANDOM and can act really quickly. (Charlat et

Managing Diversity No two humans are alike. People are different not only in gender‚ culture‚ race‚ social and psychological characteristics but also in their perspectives and prejudices. Society had discriminated on these aspects for centuries. Women and minority groups were denied of their due rights. But not any more. Since 1960s‚ when federal legislation prohibited employment discrimination‚ minorities and female applicants have become the fastest-growing segment in the work force. Diversity

Sexual selection was an idea proposed by Darwin and refers to the process in which males and females attempt to maximize their chances of reproductive success. Within a species there are certain characteristics that make individuals attractive to potential mates. An example of this is in peacocks‚ female peacocks are attracted to males with long brightly colored tails‚ even though this makes them easier to be spotted by predators. This characteristic then evolves within the species due to how males

Design Practice ( PROD 20303 ) Materials & Manufacture Materials Selection Exercise In the lecture this week you were introduced to the idea of a systematic approach to materials selection. Within the discussion‚ a number of examples were provided of ways in which a short list of materials might be identified for a given type of product using key property criteria as the method of differentiating between possible selections. Final choice can then be made by grading the candidate materials against

Natural selection forms the foundation of how we understand the ways that species have formed over time. Another form of selection is sexual selection‚ which is the selection of traits based on their roles in courting and mating. It involves attracting a mate with the greatest fitness while simultaneously portraying oneself as the best mate for selection. Fitness‚ described in natural selection‚ is the ability to reproduce and leave successful offspring that will continue the cycle. Sexual selection
