Essay Instructions: One can read rather frequently discussions on "The theory about everything", presumably everything refers to science. If this is possible, then this means that this theory will include biology in addition to the physical sciences of chemistry and physics. And this would mean that all explanations in biology can be reduced to explanations in chemistry and physics. On the other side of this position, there are many people who argue that biology is autonomous from physical sciences.

Question: Is biology autonomous from physical sciences? You can consider both chemistry and physics or just physics.You have to take either position on whether biology is or is not autonomous from the physical sciences and provide support for your position. Do not assume any positions taken or support provided in scientific papers is correct.

For biology NOT to be autonomous from physical sciences means that all biological explanations, causes and outcomes have to be reduced to those in physical sciences-- that is, the biological explanations must be able to be reformulated completely to explanations in the physical sciences.

For biology to be autonomous from physical sciences, means that there has to be at least one explanation in biology that cannot be reduced-- that is reformulated- in an explanation in the physical sciences. All that is needed is one biological explanation that can't be reduced.
