5. Evolution of life
1. Questions about evolution
When it comes to speak about evolution of life, there are two questions for many people that can seem like a mystery, and nowadays they are, but a mystery that shows perhaps philosophical and theological difficulties. The first one that can give that impression is how does this evolution take place? Does it happen randomly or is there any kind of a plan in order that life goes on evolving?
And the second question: if this kind of evolution has brought us so different forms of life, is evolution enough explanation for the existence of human being? To the first question I’d like to answer paying attention to something obvious. Let us remember how a chick builds itself. A scientist will tell us about a microscopic programming, so microscopic that in the nucleus of a cell (and a cell is only visible through a microscope) there is a molecule that has ten billion atoms, and every group of atoms is a command. In some way, all the developing of that organism is fixed there. But it is marked in such a mysterious way that not only a cell but even a million cells have exactly the same programming, all of them; and yet one of them gets to the point of changing into a core cell, and another one into a nerve system cell, and another into a cell for seeing, and another into a cell of a muscle, and another one into a digestive system cell.
How do they know when they have to do it, and how does every cell decide what they get to do? We are talking about something that is really a mystery due to the fact that components of life are not the most important thing, but the way they are structured, why you can say that information is necessary there, because if not nothing meaningful happens.
