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.
