On the Origin of Species chapter IV outlines Darwin’s proposal on how a new species is generated via natural selection over a long period of time. In Darwin’s theory of speciation‚ he proposes that all organisms within a species must express some degree of variation‚ which allow for organisms with the most advantageous variations to produce the most offspring (Darwin 10) This also means that the variations must be heritable from one generation to the next. In chapter IV Darwin uses the examples variants

What is the Sapir-Whorf hypothesis‚ and how valid is it? Introduction The debate on whether ‘language is the dress of thought’ originates in ancient Greece when Aristotle discussed the possibility that the thinking pattern influences to a certain degree the evolution of language (He‚ 2011: 1). The concept that language is ‘merely a reflection of thought and the objective world’ (He‚ 2011: 1) was re-examined several times throughout history; the conclusions drawn give us a new interpretation of
