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

The concentric zone model was among the early descriptions of urban form or Cities. Originated by Earnest Burgess in the 1920’s‚the concentric zone model depicts the use of Urban land as a set of concentric rings with each ring devoted to a different land use. The model was based on Burgess Observation of Chicago during the early years of the 20th Century. Major routes of transportation emanated from the city core‚ thus making the central business district the most accessible location in the city
