a) smallest and most specific taxonomic group

b) only one kind of organism belongs to a species group

c) members are not identical to each other (allows for individual differences)

d) a group of organisms that can make offspring that are capable of reproducing

Binomial Nomenclature

common name: name that is commonly used to identify an organism

Examples: house cat, lion, gray wolf, pet dog, coyote, leopard frog

Binomial NomenclatureBinomial Nomenclature

B) Reasons a Scientific Naming System B) Reasons a Scientific Naming System was Needed:was Needed:

1) Language differences make it difficult for scientists to communicate with each other.

2) Some organisms have more than one common name.

3) Some common names are misleading.Examples: a.Silverfish are insects, not fish.b.A seahorse is not a horse.
