- - - - Derived character is a trait that arose in the common ancestor of a lineage and is shared by all members of a clade. We find these between the nodes on a cladogram.
        
        Node is a speciation event, or a point at which the organism was now different from the following organisms.
        
        Clade is a group of organisms such as a species, whose members share homologous features derived from a common ancestor.
        
        Cladograms is an example of classification in biology which groups the organisms base on their common characteristics.
        
        Root is the common ancestor of all following organisms. The root is at the very bottom.
  - - - Dichotomous key uses the differences of items to classify items, which also means that they group items with the same characteristics.

        Can also help produce many antibiotics, vitamins and yogurt.

- - - - This is the structure of the world. It tells that how the world is made of. It shows how we break the world down from the general idea to the specific cell. This is really important for people to study the world.
- - - - Evoultion is the step that the world has been through to get to today's world. It is how us -- human are from and why every organism look like what we see today. It shows the history and it is important for us to know what is possibly going to happen in the future. Through the human history, how people look like now has been changed compare to ancient times. People used to be much shorter than now. In ancient China, there were poems talking about people's height. Most male adults used to have an average height under 160cm. In the past a few centries, people used to have higher body temperatures as well. How everything has changed can be called as an evolution. It is absolutely neseccary for us to learn in order to know what to do next.
- - - - More importantly, the emergence of these viruses may be a "product" of the highly developed human civilization. As humans destroy more and more nature environments, global warming is already causing so many problems. It has been reported that the ancient viruses which exists in glaciers are unknown and they may have huge impacts on human world. But it is obvious that the medical systems and scientific systems are not ready for that to come. Much of that burden will fall on scientists to study the origin and evolution of various microorganisms, to study the transmission laws and mathematical models of human infectious diseases, to establish more accurate disease warning and tracking systems, to develop drugs, to prepare vaccines, to study the basic biological mechanisms of diseases.
        
        In this highly technological world, should we also put more attention on the natural environment which is necessary for every individual to survive?
        
        As the natural environment keeps being polluted, more and more virus will be found and may also cause dramatic changes to the world, studying virus can help can to prevent the next pandemic.
