Classification – History In 1758, Carolus Linnaeus, [also know as Carl] the Swedish naturalist and founder of biological classification, published his 10 th edition of the Systema Naturae [first published in 1735]. This book of names is the commencement date for classification. No names before this date count today. https: //onthejob. education 5

Classification – History The 10 th edition contained 4, 400 species of animals and 7, 700 plants. People from all over the world sent their specimens to Linnaeus to be included. Linnaeus was also known as Carl von Linne. He formalised the modern system of naming organisms called binomial nomenclature. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. Example: Humans are classified as Homo sapiens Note the capital and the italics for Homo sapiens https: //onthejob. education 6

Classification The classification of humans: Homo sapiens. The name of the species must include both the genus name and the specific epithet. Domain: Eukaryote Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Primata Family: Hominadae Genus: Homo Species: sapiens https: //onthejob. education 7

Classification Six Kingdom System Animal Kingdom – eukaryotic, multicellular, heterotrophs, no cell walls. Examples: invertebrates (without backbones) and vertebrates (with backbones) Plant Kingdom – eukaryotic, multicellular, autotrophs, have cell walls. Examples: mosses, ferns, flowering and seed plants Fungi Kingdom – eukaryotic, most multicellular and some unicellular, heterotrophs (break down other organic materials to obtain food), cells with cell walls but not green. Examples: mushrooms, molds, and yeasts Protist Kingdom – eukaryotic, many are single-celled and others are multicellular, some heterotrophs and others autotrophs. Examples: come in a wide variety of forms: animal-like, such as amoeba, some are plant-like such as algae, and others are fungi-like. Eubacteria Kingdom – prokaryotic, unicellular, some autotrophs while others heterotrophs. Examples: bacteria and blue-green algae. Arcaeabacteria Kingdom - prokaryotic, unicellular, some autotrophs while others heterotrophs, live in extreme conditions. Examples: bacteria living near ocean thermal vents or in a cow’s stomach https: //onthejob. education 9

Activity 2: Classification Shops classify their products for sale. . In small groups of 3 – 4, order the animals into GROUPS. You can have as many groups as you like, BUT, one animal by itself is not a group. Also, you don’t want any animals being in a group where they don’t belong! https: //onthejob. education 10

Activity 2: Reasoning You need to have good reasons for placing your animals in these groups. You will need to explain why the animals are grouped and use the word “because”. Each group will explain their groupings. Look at your worksheet to see the animals You have now classified these animals through their Morphology [physical characteristics] and their behaviour. https: //onthejob. education 11
