Classification and organization of Life
This chapter looks at the way Biologists classify living organisms. We start by looking at the necessity and reasons for classifying life. It allows scientists to speak a precise and common language. It allows the organization and distribution of accurate and useful information.
From there we move on to look at the history of classification and how classification systems have changed over time. These changes have been brought about by better technology and increases in our own knowledge. Classification once consisted of essentially putting similar organisms into "piles" with other similar organisms. The focus was on common characteristics and lumping things together that were the "same." However, today, scientists seek to classify life based on common ancestry. We can now use DNA evidence to confirm or disprove our assumptions about which organisms are, and are not, closely related to each other. The ultimate goal is the construction of a complete and accurate Family Tree of Life. |
