5.5.1 Outline the binomial system of nomenclature.

Was Linnaeus a racist? Carolus Linnaeus proposed 4 biological varieties or races of humans: Homo sapiens Eoropeus albescens ("white" people from Europe) Homo sapiens Africanus negreus ("black" people from Africa) Homo sapiens Asiaticus fucus ("dark" people from Asia) Homo sapiens Americanus rubescens ("red" people from the Americas)

Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Carnivora Family: Canidae Genus: Canis Species: C. lupus Kingdom: Plantae Phylum: Magnoliophyta Class:Liliopsida Order: Asparagales Family: Orchidaceae Subfamily: Vanilloideae Genus: Vanilla Species: V. planifolia List seven levels in the hierarchy of taxa—kingdom, phylum, class, order, family, genus and species—using an example from two different kingdoms for each level.

5.5.3 Distinguish between the following phyla of plants, using simple external recognition features: bryophyta, filicinophyta, coniferophyta and angiospermophyta.

5.5.4 Distinguish between the following phyla of animals, using simple external recognition features: porifera, cnidaria, platyhelminthes, annelida, mollusca and arthropoda.

5.5.5 Apply and design a key for a group of up to eight organisms.

So… what is a Dichotomous Key? Is a way to classifiy organisms into groups based on characteristics that distinguish them from other organisms.

How to construct a Dichotomous Key
