Question

igreen · Answer

As new organisms were discovered, new kingdoms were created to sort them based on ability to interbreed.
 It was discovered that the organisms in each of the five kingdoms have a different method of obtaining nutrients and are therefore fundamentally different.
 Technological advances led to the discovery of single-celled organisms and increased our understanding of relationships between organisms.
 Genetic research led to the discovery that each of these five kingdoms has a unique evolutionary ancestor.
