Such sequences are postulated to be the natural consequence of the four fundamental natural forces and the characteristics of matter and energy. Stars, planets, solar systems, and galaxies are examples. Its fundamental claim is that intelligent causes are required to produce the information processing systems, processed order and irreducible complexity reflected in living systems. Microevolution is also evidenced by plant and animal breeders as they change the outward appearance or behavior by selective breeding. Darwinian evolution above the species level producing new anatomical structures.
Macroevolution is viewed as the extension of microevolution over very long time periods.
It is build by systematically seeking explanations for what we observe in nature. The tools of Science are observation, experiment, and logical argument which require strict empirical standards and a healthy skepticism. Scientific explanations are ultimately built upon observations. From these, hypotheses and theories are developed. A hypothesis is a testable statement about the natural world that can serve as the basis for further inferences, explanations, and most importantly, predictions.
