Which two species are the most closely related?

What is the best explanation for the continual changes in the classification system of organisms? 

• All organisms struggle for existence and become extinct.
• All organisms compete to be at the top of the food chain
• Technological advances have allowed scientists to better compare organisms.
•  More species have been discovered, but scientists have not analyzed all the data 

What is the difference between the full classification of organisms and their scientific names?

• The full classification of organisms and their scientific names vary in different countries.
• The scientific names of organisms include the order and family of the organisms, but the full classification includes only the species name.
• The full classification of organisms will include more categories of organisms than their scientific names.
• The scientific names of organisms include a single nomenclature, but the full classification includes various nomenclatures.
