Organizing Life’s Diversity

Terminology Classification – the grouping of objects or information based on similarities. (ie. organizing your music collection) Taxonomy – the branch of biology that groups and names organisms based on studies of their different characteristics.

Who developed the system of classification? Aristotle developed the first widely accepted system of biological classification Two groups: Plants and Animals Carolus Linnaeus developed classification system based on physical and structural similarities of organisms which is still used today and includes classification based on structural similarities and evolutionary relationships of species.

How do we name organisms? Binomial Nomenclature – Two word naming, developed by Linnaeus to identify species First word = genus Second word = species (ie. Homo sapiens = modern humans) Note: Scientific names are always written in italics or underlined

Today’s phylogenetic classification uses a hierarchy of taxa to classify organisms. From largest to smallest (A mnemonic to help you remember) Kingdom King Phylum Phillip Another way to help you Class Came remember the order, sing t Order Over groups to the tune of Family For “Yankee Doodle.” Genus Green Species Silk

The phylogeny for a Bobcat is: Kingdom Animalia : Phylum Chordata Class Mammalia Order Carnivora Family Felidae Genus Lynx Speices Lynx rufus

What are the six kingdoms?

Evolutionary History Phylogeny describes the evolutionary history of a related group of species All organisms on Earth evolved from a single ancestor Life on earth began about 3.5 billion years ago; since that time, new species have emerged, lived and died out New species evolve from pre-existing species

Evidence for the relationships between living things Through fossil evidence, physical similarities, and molecular similarities between ancient species and modern species have been found. Physical and molecular similarities between diverse species has also been found.

How do we classify living things based on evolutionary information? Cladistics – a type of classification system based on phylogeny (evolutionary history) Scientists use a cladogram to diagram evolutionary relationships of traits
