Diversity of Life Chapter 17.1 we are going to look at the history, purpose, and methods of classification of species on Earth. The classification is called taxonomy and a Biologist that specializes in taxonomy is called a taxonomist.

When you want to go buy some music you go to a music store that has all of the music grouped together in catagories. By knowing in which grouping the CD is in, you can know that the music on the CD has certain characteristics. It works the same way for understanding life on Earth… How would knowing in which section of the music store an unfamiliar CD is located be helpful in gathering information about the CD?

We classify organisms Classification means sorting things into groups. to make recognition and description easier. And just like the CDs in the music store are classified as particular types of music based on the characteristics of the music, Organisms are divided into groups according to their characteristics and given scientific names. Expanding on Linnaeus’s work today’s taxonomists try to identify the underlying natural relationships of organisms and use that information as a base for classification…

In order to better understand the organisms of Earth, Biologists organize them into groups.

The Linnean hierarchical classification was set up with the species as the smallest unit, and that each species was nested within a higher category. In the late 18th century Swedish botanist, Carolus Linnaeus developed a method that was based on physical and structural similarities of organisms. Linnaeus’s system was based on physical and structural similarities of organisms. Some characteristic of the organisms were similar to each other so they get grouped together. Carolus Linnaeus

Binomial Nomenclature A two word naming system used to identify species For example Man in English is Hombre in Spanish, Herr in German, Ren in Chinese, and Homo in Latin. If a scientist refers today to Homo, all scientists know what organism/taxon he or she means. The first thing Linneus had to do was come up with some sort of universal language for his classification system. Linneus developed the concept of binomial nomenclature, whereby scientists speaking and writing different languages could communicate clearly. For instance…. Linneus settled on Latin, which was the language of learned men at that time. So…

Binomial Nomenclature A two word naming system used to identify species Homo sapiens Identifies the genus of the organism Describes a characteristic of the organism Italicized in print or underlined when handwritten Let’s take for example the scientific name for man -- Homo Sapien The first term identifies the genus of the organism. A genus consists of a group of similar species and is the next step up from species in the hierarchy classification system. The second term is a descriptive term it describes the organism. The scientific name for each species is a combination of the genus and descriptive names. Modern humans are in the genus homo and one of their characteristic is intelligence, the Latin word sapiens means wise. Taxonomists continue to use Latin because it is no longer used in conversation so it doesn’t change. There are particular ways the scientific name is written… Although a scientific name gives information about the relationships of an organism and how it is classified many organisms have common names, however common names can be confusing…a sea horse isn’t a horse it is a fish and many organisms have different common names depending on the part of the world The first letter of the genus name is capitalized The first letter of the descriptive name is lower case common name

How living things are classified Kingdom Phylum Class Order Family Genus Species

How living things are classified Kingdom Phylum Class Order Family Genus Species Organisms that look alike and successfully interbreed belong to the same species A group of similar species that have similar features and are closely related. A group of similar genera, each sharing similar characteristics The smallest group is the species, one or more species with similar characteristics make-up a genus, one or more genera with common traits compose a family, a group of families that share traits make up an order, orders with common characteristics compose a class, classes make up a phylum, and a Kingdom contains one or more phyla Each of these categories is referred to as a TAXON or TAXA is plural. Each Taxon contains sub groups of the smaller taxa that have something in common. Let’s take a look at cats – cats, lions, leopards, etc. A lynx and a mountain lion do not belong to the same genus as domestic cats, lions and leopards this is because their jaws contain 30 teeth and the lynx and bobcat’s jaws contain 28 teeth. They do however belong to the same family. All Cats within the family of Felidae share certain characteristics – short faces, small ears, forelimbs with five toes and hind limbs with four toes. Is a taxon of similar families Is a taxon of similar orders Is a group of similar classes A group of similar phyla or divisions

How living things are classified Kingdom Animalia Phylum Chordata Class Mammalia Order Carnivora Family Felidae Genus Felis Genus Lynx Species Species Take a mountain lion, a domestic cat, and a puma – they are each different species. The bobcat and the lynx are also species. The mt lion, domestic cat, and the puma have several common traits one of which is that they all have 30 teeth. When a group of species share specific common traits they are all put into the same genus, the mt lion, domestic cat and the puma are in the genus Felis. The bobcat and the lynx don’t share as many traits with those species found in the genus felis, one difference is they only have 28 teeth, they are put into a different genus where they have more share more traits with other species, they are in the genus lynx. Both genra have enough common traits, in fact all of the genra that contain cat species are grouped together into the family felidae The family felidae is grouped together with other familys that contain meat eaters and placed in the order carnivora The order carnivora along with all other orders that contain mammals are grouped together in the class mammalia The class mammalia along with all the other classes that contain organisms with backbones are grouped together in the phylum chordata The phylum chordata along with all the other phyla of animals are grouped together into the kingdom animalia As we go up thru the groups the number of organisms increases. Species are smaller more select or specialized – Kingdom is broader contains a lot of different types of organism

Kingdom Phylum Class Order Family Genus Species Example: Man Animal Chordata Mammalia Primate Hominidae Homo H.sapien Using or previous example of the species Homo sapien, common name MAN. Man belongs to the kingdom Animal, the phylum chordata; chordata is not the only phylum contained in the kingdom animal. Man is in the class Mammalia, there are several other classes within the phylum chordata. The order primate, the family hominidae the genus Homo and the species sapien. Kingdom: Animalia (all animals, which are heterotrophs) Phylum: Chordata (all animals with a notochord) Subphylum: Vertebrata (all vertebrates, i.e., with a spinal column) Class: Mammalia (all vertebrates whose females secrete milk to nourish young) Order: Primates (mammals with five opposable digits, binocular vision, and large brains) Family: Hominidae (all hominids, current and ancestral) Genus: Homo (upright primates; 'man') Species: Homo sapiens (humanity; 'wise man') The number of kinds of organisms decreases down the spectrum until there is only one kind of organism left for the group 'species‘.
