EVOLUTION IN NATURE: LESSONS FOR YOUR LIFE. Nature did not have a plan to make a tiger, a horse or Man. It just happened along the way.
Everything in this space-time Universe evolves; including your Life. Evolution is survival of the fittest. But it is not strength or intelligence that determines fitness for survival. It is the ability to adapt to the ever-changing environment.
Those who are able to constantly adapt, survive. Because Evolution has no pre-determined plan nor a targeted path.
Evolution is open-ended. It meanders along adapting to its ever-changing environment. It is affected by, and in turn affects the environment (and its inhabitants). [Coevolution and Feedback Loops].
In the same way, your Life is not pre-determined but meanders along, affected by events and people, and in turn affecting events and people in a feedback loop. What you will be tomorrow depends on what you do today. And what you do tomorrow makes you what you will be the day after tomorrow.
