An organism identified with binomial nomenclature includes which two taxa?

• class and order

• family and genus

• genus and species

Carl Linnaeus developed a binomial classification system for living things. Why is this contribution important?

• because it created new species for identification

• because it created specific scientific names for living things

• because it created the taxonomy system as it is known today

• because it created common names for species with existing scientific names

Which taxonomic category is higher than the others?

• Class

• Genus

• Family

• Phylum

Scientists currently classify organisms based on features they share. How will this most likely change in the future?

• They will be classified based on DNA analysis.

• They will be classified based on similar organs.

• They will be classified based on common descent.

• They will be classified based on protein production.
