Influence of Physical Laws

physical laws and biological function

Now for those of you who are mathematically dyslexic, I will tell you that these are the only equations I intend to show. They're all in here to illustrate two points. These are physical laws basically drawn at random that can be used to quantify the performance of the biological functions that I've talked about. The important thing is that if you look at the mathematics of each of these equations, you see two different kinds of parameters. There are some that are constant, regardless of where you are on the planet and regardless of where you are in the flow of historical time. Others are under the control of plant growth and development.

So for example, the density of air or water, which is shown here amongst other physical features, has not varied dramatically over the last billion years of evolution and remains the same for any part of the planet that you happen to visit. So essentially, these parameters which influence the biology of plants are essentially out of the control of biological entities. They are things that are given. They're historical gifts or in some cases, curses. It depends on the function and the environment we are considering.

But, if you look at the same equations, you will see that there are parameters that are decidedly within the ability of living things to control. So for example, if you look at the law of buoyancy, you see that you have the gravitational constant which plants or animals cannot manipulate. But, you also see volume, which refers to the amount of biomass either in the plant or the animal. That volume can be altered by an organism either through its ontogeny as it grows and develops or through evolutionary modification. So as a consequence, organisms actually can control the end result of these mathematical formulae and they can therefore cope with their environments in very sophisticated ways.
