The Units and Levels of Selection by Samir Okasha (Ch 8‚ A Companion to Philosophy of Biology) Traditional Darwinian View – * Though Darwin treats individual organisms as basic unit of selection‚ other possibilities can be seen * Lewontin (1970) – Natural Selection will operate on any level that exhibits ‘heritable variation in fitness’. * Hence the question of level seems purely empirical – but is not. Historically – * The debate of Levels of Selection can be traced back to

Natural selection Natural selection is one of the basic mechanisms of evolution‚ along with mutation‚ migration‚ and genetic drift. Darwin’s grand idea of evolution by natural selection is relatively simple but often misunderstood. To find out how it works‚ imagine a population of beetles: 1. There is variation in traits. For example‚ some beetles are green and some are brown. 2. There is differential reproduction. Since the environment can’t support unlimited population growth‚ not all individuals

Natural and sexual selection One of the first and central mechanisms proposed by Darwin during his life was that of "natural selection." Some may refer to this as "survival of the fittest‚" whereby species that produce offspring have been successful in doing so because they have produced random individual features which have lead them to live longer and pro-create offspring with the same inheritable desired features. Not all individuals will be able to reproduce‚ therefore only the fittest will "multiply

to evolution by way of Natural Selection‚ Artificial Selection‚ and Sexual Selection. The process of evolution is seen in species that undergo changes over long periods of time by adapting characteristics which will better suit them to their environments. By utilizing a combination of both hypothetical imagery and scientific observation‚ Darwin has developed a persuasive argument intended to shed light on the origins of life. Natural Selection Natural selection is understood as the evolutionary

Books 2012). The word mate‚ which is another way of saying friend‚ is typical Australian slang and it is mainly used in an informal context. The word mate suggests openness‚ at least to a relationship of equals (Richard Castles‚ The Big Issue 4-17 November 2008).

How Natural Selection has Shaped the Modern Mind Abstract Mental and emotional faculties have been widely accepted as complex‚ useful‚ and non-arbitrary pieces of the human mind. If these faculties are actually nonrandom parts of our development they must have come from either divine design or natural selection. While there are those that believe that people are created in some divine being’s image‚ many recognize that Darwin’s theory of natural selection has shaped many aspects of the

Kin Selection vs. Multilevel Selection In The Social Conquest of Earth by Edward Wilson‚ he argues that kin selection is not a valid theory and proposes a better theory called multilevel selection. This has been seen as a controversial proposal because for generations previous to multilevel selection‚ kin selection was the standard explanation of evolution. Through the use of various examples‚ Wilson makes a convincing pro-multilevel-selection argument. Kin Selection‚ also known as inclusive fitness
