In 1990, Carl Woese introduced the three domain system for classifying living things, after the advancement of DNA analysis allowed for a comparison of species genetic code. Which of the following is the best explanation for why domains were added to the previous system of classification?

• The old system of classification was wrong and needed to be corrected.
• New species are evolving too quickly to keep up with the old system of classification.
• Domains have always been included, they were just made official recently.
• Some organisms, which were previously characterized together, were determined to be genetically very different

The Florida Panther was once considered to be a subspecies of cougars and given a special trinomial taxonomy of Puma concolor coryi. Current scientists however, have studied the Florida Panther and removed the subspieces classification to only Puma concolor. Which of the following would most likely explain why the classification of the Florida Panther changed.

• New genetic evidence suggests a much closer relationship between the Florida Panther and other cougars
• Shared features between the Florida Panther and other cougars were also found in newly discovered organisms in the world.
• Advanced technologies have shown a large difference in cell structure between the Florida Panther and other cougars.
• Trinomial naming conventions are no longer used by longer used by scientists because only the genus and species are important in taxonomy.
