Evolution is a process of increasing complexity.
In biology, evolution is the process that changes the genetic code of organisms to go from the simplest to the most complex. These aleatory changes can benefit or impair the organism. When the organism is benefited by the changes your chance to survive increases and the population of this variant should prevail over the old one, but when the changes impaired the organism the chance to survive decreases making more probable that this variant be extinct in a little time.
The changes benefit the organism when follow the rules described at our post “Establishing the rules“, that is, when reduce the spent of energy, increase the reproductive success, reduce its environmental impact or increase the area where the organism can live.
Several factors can be responsible by evolution, such as, transcript errors of genetic code, crossing over and environmental variable changes (these changes can affect the result of chemical reactions or affect physically the molecules into cell).

We will divide the forms of life based on:
1. Number of cells
Acellular, unicellular or multicellular, respectively, composed by no cell(such as prions and virus), one cell(such as bacteria) or many cells(such as algae, coconut trees and cats).
2. Structure to locomotion
Stationary, pseudopods, cilia, flagella, tail, paws, legs, wings.
Liquid or dry.
4. Complexity (multicellular only)
Simple or complex, respectively, without specialized cells or with specialized cells.
Obviously, we should have more simple organisms than complex ones. Therefore, it should have more virus than bacteria, more bacteria than multicellular organisms and more of simple multicellular organisms than complex multicellular organisms.
It is true due to the fact of organisms of higher complexity will probably use the organisms of lower complexity as food (such as an ox eating grass), being rare the opposite (such as a carnivorous plant).
By the same reason the simpler structure of locomotion should be prevalent over the complex ones.
Lastly, it is expected that the life begins at a liquid and moves to a dry environment after some time because the liquid can dissolve the chemical substances and facilitate the chemical reactions that are prerequisites to life.
The increase of the complexity of organism is accompanied by the increase of consciousness about the environment and about the organism itself. In fact, we can measure the level of consciousness of an organism by analyzing the size and complexity of its genetic code.

Q. What should be the primary objective of any form of life?
A. Minimize the energetic cost to stay alive.
E. Stay alive is costly. The higher the energetic cost to stay alive, the greater the chance of dying before it can reproduce and the form of life will be extinct. Therefore, any form of life should try to be as energetically efficient as possible.
Q. What should be the secondary objective of any form of life?
A. Maximize reproductive success.
E. Since any form of live is going to die at some point it is necessary to ensure that at least one descendant can survive at least the time it takes to reproduce as well.
Q. What should be the third objective of any form of life?
A. Minimize the environmental impact of your own actions.
E. If the actions of a form of life change too much the environment, these changes can transform a suitable environment into a toxic environment for the form of life, killing the organism and all its descendants.
Q. What should be the fourth objective of any form of life?
A. Adapt itself to colonize new environments.
E. This adaptation implies genomic changes that can alter the shape or color of the organism, increase resistance to a particular toxic element (such as oxygen, sulfur, chlorine, arsenic, etc.) or environmental variable (such as temperature, pressure, humidity, acidity, radioactivity, etc.), create new structures or organs (such as arms, legs, wings, lungs, etc.), or create a new form of life.
