Learn about the 6 kingdoms of living things and the importance of classification in organizing and understanding the diverse world of organisms. Explore the history of taxonomy and the concept of binomial nomenclature.

THE 6 KINGDOMS OF LIVING THINGS ARE: • Archaebacteria • Eubacteria • Protista • Fungi • Plants • Animals
Why are things grouped (classified)? • Organization • Organization • Organization • Communication • Communication • Communication
Classification • The systematic grouping of organisms into categories on the basis of evolutionary or structural relationships between them. • Also known as the science of taxonomy.

Early history • Aristotle-first to organize living things • 2 large groups-plant and animal
Taxonomy • Is the science of naming and classifying organisms-has sub-groups and names • Father of taxonomy is Carl Linnaeus
KPCOFGS • King • Phillip • Came • Over • For • Good • Spaghetti
Humans Chimpanzee • Kingdom Animal Animal • Phylum Chordata Chordata • Class Mammalia Mammalia • Order Primates Primates • Family Hominadae Pongidae • Genus Homo Pan • Species sapiens troglodytes
What is a primate? • hands and feet which are adapted for grasping, • their thumbs and big toes can be moved to touch the other digits and are known as opposable digits, • eyes on the front of the face - binocular vision. This is a great help in judging distance accurately,
What do all hominids have? • bipedalism and large brains • share more than 97% of their DNA with the modern human genome, and exhibit a capacity for language or for simple cultures beyond the family.
Binomial nomenclature • C. Linnaeus developed a system that gives a 2 word name to every organism. • The 2 word naming system is called binomial nomenclature • It helps to avoid confusion • It uses the Genus and species name only
Some common names • Canis familiaris - dog • Felis domesticus - cat • Canis lupus - wolf • Vulpes vulpes - fox • Ichthyomyzon gagi - brook lamprey • Populus deltoides - cottonwood • Cercis canadensis - red bud • Diospyros virginiana - persimmon • Carya illinoensis - pecan
Classification and evolution According to Charles Darwin’s theory of evolution, members that are grouped together have similar characteristics because they descended from a common ancestor Classification shows the evolutionary relationships of organisms
A dichotomous key • is used to identify organisms that you do not already know. • Means "two forks". • A dichotomous key is one tool that can be used to identify trees or any other organism
