  12. 12.  Theophrastus (370–285 BC) was a student of Aristotle and Platon. He wrote a classification of all known plants, De Historia Plantarum, which contained 480 species. His classification was based on growth form, and we still recognise many of his plant genera, like Narcissus, Crocus and Cornus.
  13. 13.  Dioscorides (40–90 AD) was a greek physician, gathered knowledge about medicinal plants. Between 50-70 AD he wrote De Materia Medica, whichcontained around 600 species. The classification in his work is based on the medicinal properties of the species.

  29. 29.  One of the earliest authors was Caesalpino (1519–1603) in Italy, who is sometimes called "the first taxonomist". In 1583 he wrote De Plantis, a work that contained 1500 species. His classification was based on growth habit together with fruit and seed form, as was that of Theophrastos.
  30. 30.  Two Swiss brothers Bauhin (1541–1631; 1560–1624) wrote the work Pinax Theatri Botanici in 1623. The word Pinax means register, and the work is a listing of 6000 species.
  31. 31.  By this time, species were known with many different names in different books, and Pinax Theatri Botanici made a welcome order in the taxonomic world. The Bauhin brothers recognized genera and species as major taxonomic levels.
  32. 32.  The English naturalist John Ray (1627–1705) wrote several important works through his life. His most important contribution was the establishment of species as the ultimate unit of taxonomy. In 1682 he published Methodus Plantarum Nova, which contained around 18, 000 plant species, a result of a relatively narrow species concept.
  33. 33.  His complicated classification was based on many combined characters, as opposed to earlier taxonomists. Ray aimed at publishing a complete system of nature, which included works on mammals, reptiles, birds, fishes and insects, the latter including pioneering entomological taxonomic work.
  34. 34.  In France Joseph Pitton de Tournefort (1656– 1708) constructed a botanical classification that came to rule in botanical taxonomy until the time of Carl Linnaeus. In 1700 he published Institutiones Rei Herbariae, in which around 9000 species were listed in 698 genera. He put primary emphasis on the classification of genera, and many genera were accepted by Linnaeus and still in use today.
  35. 35.  Tourneforts plant classification was exclusively based on floral characters. Tourneforts system was the one used by Linnaeus as a young student, but whereas Tournefort denied the presence of sexuality in plants, Linnaeus on the contrary based his system on that argument.

  58. 58. TRANSFORMING BOTANY AND ZOOLOGY INTO A SCIENCECarl Linnaeus started his career by publishing a system of all living thingsand minerals in 1735 called Systema Naturae. In this he introduced thesexual system of plants, an artificial classification based on the sexual partsof the flower: The stamens and pistils. Carolus Linnaeus (23 May 1707 – 10 January 1778), also known as Carl von Linné or Carl Linnaeus. Swedish botanist, zoologist, and taxonomist.
  59. 59. TRANSFORMING BOTANY AND ZOOLOGY INTO A SCIENCEIn a time when people debated whether plants had sexuality or not, this suggestionfrom an unknown person not belonging to any classical European school of naturalsciences more or less shocked the scientific world.
  60. 60. TRANSFORMING BOTANY AND ZOOLOGY INTO A SCIENCEHowever, the practical use of the system andLinnaeus careful observations persuaded thecritics and Linnaeus sexual system of plantsbecame the highest fashion also outside thescientific community. Linnaeuss sexual system for plants, based principally on the number of male and female sexual organs in flowering plants, where part a has one stamen (male) and one style (female), part b has two stamens and one style, and so forth. (Illustration by Georg Dionysius Ehret, 1736)

Linnaeus established many of the rules taxonomists use today. Terms like corolla, stamen, filament and another were created by him, as well as well-known taxon names like Mammalia.
  62. 62. TRANSFORMING BOTANY AND ZOOLOGY INTO A SCIENCEAfter a long life with a massive publication in the philosophy and practicality ofsystematics, Linnaeus had laid out the foundation for botany and zoology, and it wasnow time for subsequent taxonomists to improve this newborn science. Carl Linnaeus was born in southern Sweden. His father was a gardening enthusiast, and this interest in plants seems to have rubbed off on the son.

  76. 76. • The systems of plants and animals were now huge, in flowering plants approaching a quarter of a million species.
  77. 77. THE GERMAN BIOLOGIST WILLI HENNIG• The German biologist Willi Hennig (1913– 1976) founded the cladistic era in 1966, by stating that only similarities grouping species (synapomorphies) should be used in classification, and that taxa should include all descendants from one single ancestor (the rule of monophyly). Hypothesis on systematics could now be tested through cladistic methods.
  78. 78. • The new method, called cladistics, was controversial, and it took around 20 years before it started to become established. As earlier during the century, the reformation of systematics happened earlier among zoologists than botanists. The 1980s were a decade of great debates and discussions where scientists claimed themselves to be for or against cladistics.
  79. 79. • With the invention of the polymerase chain reaction (PCR), which made it economically possible to amplify DNA-sequences for use in systematics, and the strong development of computer programs that could handle large data sets, cladistics became more or less the rule for systematic work.

  83. 83. O With the breakthrough of cladistics analysis and constructions of phylogenetic hypotheses, the taxonomy built on the Linnaean hierarchic system became a matter of intense discussion and criticism.
  84. 84. O Two zoologists from USA, Kevin de Queiroz and Jacques Gauthier, started the discussions in the 1990s and laid the theoretical foundation to a new nomenclatural code for all organisms, the PhyloCode.O A meeting in Harvard in 1998 drew out the lines for a PhyloCode, and a first draft was published on the web in 2000.
  85. 85. O The PhyloCode reflects a philosophical shift from naming species and subsequently classifying them (i.e., into higher taxa) to naming both species and clades.
  86. 86. O The main idea with the PhyloCode is that only species and clades should have names, and that all ranks above species are excluded from nomenclature.O The aim is to change current names as little as possible and to build the stability on clades rather than on ranks.
  87. 87. O The PhyloCode is still only a draft, it is controversial, and has led to a worldwide and very interesting debate.O Its success will depend on the number of taxonomists that will use it for their taxonomic work.
