Why do we Classify?Why do we Classify?
• To group organisms according to similarities
• Taxonomy is the science of classifying organisms.

Binomial NomenclatureBinomial Nomenclature
• Binomial Nomenclature - the formal system of naming species. (Bi = two, nomial = names)– Latin is the language in which scientific names are written.
• Carolus Linnaeus (1707 – 1778) a Swedish botanist , came up with the b.n. system.
• Aristotle was the first scientist to group organisms based on physical characteristics.

Scientific NamesScientific Names
• The GENUS is the 1st word in the scientific name. Always capitalized
Example : Amoeba proteus
Homo sapiens
• The SPECIES is the 2nd word in the scientific name. Always lowercase
Example: Amoeba proteus
Homo sapiens

Phylogenetic TreePhylogenetic Tree• A Phylogenetic Tree is a way to organize living things
and show how they are related.

CladogramsCladograms
• Cladograms are a way to show shared or lost traits between related organisms

How do we know how to How do we know how to classify?classify?
• Similar Structures – The bones in a
bat’s wing are almost the same as the bones in a human hand
• Similar Behaviors– All mammals nurse
their young
• Similarities in genes (DNA sequence or proteins)– Human and
Primate DNA is 99% similar

Evidence for Evidence for Classification/EvolutionClassification/Evolution
• Homologous structures: similar bone structures in different organisms
• Fossil Record: Past organisms can be studied through fossils
• Gene similarities: matching DNA sequences
• Embryology: similar development patterns in unborn species of different species
• Hybridization: ability to successfully interbreed different species.
