Question

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?

Answer 1

Evolutionary analysis of organisms

Explanation:

• Some organisms, which were characterized together determined to genetically very different .
• Using the analysis of RNA developed by Carl Woese, scientists are now able to classify  the human evolution
• living things based on genetic information instead of expressed characteristics.
• Genetic  information is more specific and can give clues as to the evolutionary ancestry of  organisms.
• That is the reason adding of various domains in previous system of classification is allowed for a comparison of species genetic code
