What is living and what is not? It is almost impossible to be completely accurate with what is living and what isn't with such a large variety of organisms in our world. To the human eye it may be very difficult, but there are many different ways to look further into a organism and tell whether or not it is living. Many aspects of viruses and protein prions are living, but some are also many things that make the feel not so living. As time changes organisms begin to change themselves and adapt to their surroundings. As these organisms change and adapt they become even more efficient in there environment and thrive in life. The classification of "living" and "dead" isn't something that is to classify. You must look at all the different parts and behaviors of the organism before one could classify and make a accurate decision.
