Rocks are easier than People or any living thing for that matter even a one celled ameba . There is a certain comfort in geology since there are really on 3 type of rocks to remember and they can go back and forth being one or the other. For example, at one point a rock can be igneous and then metamorphic at some other time a billion years later. There are tons of complex things to know about life forms the least of which is that they are all made up of cells that have molecules that reproduce them. Think about enzymes, catalyst that are not changed by the chemical reaction they cause. How is that possible? Then we can get into the complex behavior of various types of life and how they react to each other and to the world. Zowie! I can see why people eschew biology in favor of geology. Take a nice drive to a road cut on a New England autumn day, pick up a few rocks and analyze them in the comfort of a lab. No Jane Goodall's there, spending a life time sitting in a jungle with a bunch of apes trying to understand them.

I wrote this after thinking about how much I love rocks. It is really shallow though but I will publish it anyway as that hasn't seemed to stop me before. The real trouble with geology is that it is almost impossible to get a straight answer from a geologist. Ask one some time, "what kind of rock is this?: and you will get way too much information about it when all you wanted to know was something like,"It's granite, or slate or Gold (even better)."
