Evolution and Classification Test Darwin/Lamarck Darwin’s observations: Usually the numbers of offspring produced are far greater than the ones that survive Natural resources are limited. This leads to a struggle for existence with only a fraction of offspring surviving to the next generation Slight variations (mutations) occur by chance within a population These variations are inheritable Darwin concluded that living organisms were evolving through

Chapter 18 Outline: Diversity and Variation 18.1 The Species Concept TAXONOMY- classifying organisms in ways that reflect relationships and help distinguish one type of organism from another. SPECIES- group of organisms that is capable of breeding offspring‚ or mating‚ with another in nature to produce fertile offspring. Individual members of a species may look very different from eachother. Such differences among members of a species are known as variations Natural selection

according to their shape. Carl Linnaeus (1707-1778)‚ the Swedish botanist‚ naturalist and explorer proposed a method of classification known as the binomial system‚ which assigns a pair of names to each species: The name of the genus which it shares with other related species and the species name‚ which is unique. The rules of scientific nomenclature are specified in five codes: animals‚ plants‚ cultivated plants‚ bacteria and viruses Subspecies Subspecies‚ varieties‚ species or geographical
