The key to evolution: Biologically complex organisms


Life on Earth commenced with the emergence of the most basic life form, that of a single celled organism.


Strangely enough bacteria are seldom mentioned during a discussion of evolution. You may be surprised to hear that bacteria reigned for three quarters of the time since life first appeared or for more than three billion years, and are still the most prolific organisms in the world today. Not until four hundred million years ago did the first insects appear.


Let’s pause and consider how Darwin’s model would explain the arrival of physically more complex animals. Darwinism argues that there is no purpose in evolution other than to survive and reproduce. If this is indeed the case then in effect it would be irrelevant for anyone to examine the next phases of evolution, because we should find more of the same. Darwin ignores physical, emotional and cognitive developments, which manifested as prominent features in the fourth quarter of life on Earth.


This mundane view brands Darwin’s model as simplistic. The general scientific perspective is that simplistic models do not provide sound explanations for life’s issues, because of the inescapable fact that life is complex. Darwin’s organic model suggests that there is no change in principle in terms of development from bacteria to the insect phase to the more biologically complex organisms such as the dinosaurs and the mammals. Ignoring physical, emotional and cognitive developments in animals is an incredible deficit for a model that purports to explain the intricacies of life.


In contrast to Darwinism, my view is that because the development in the insect phase was still incomplete there is a next phase of development into physical bodies that have a greater biological complexity. Instead of focusing on the organism’s physical strengths and capabilities, I will instead focus on how an organism contributes to the process of evolution. An organism contributes to the evolution process by reproducing. After all, we are concerned not with how an organism survives, but how the process of evolution works. This process is contributed to by every living organism, and the manner in which it reproduces leads to an understanding of the organism’s attained level in evolution.


The key to evolution

The manner in which an organism survives may vary from species to species, but the final analysis of such an investigation would at best classify organisms as omnivores, carnivores or herbivores. A particular or remarkable survival skill provides no indication of an organism’s place on an evolution scale. However, concentrating on how each organism through reproduction contributes to the process of evolution reveals some amazing facts, which in turn explains the organism’s behaviour and its place on the evolution scale. This investigation in the manner of reproduction starts with bacteria and is followed through to the larger biologically complex organisms. The process of evolution can unobtrusively be observed from insects to the larger organisms, but note that bacteria multiply through cell division.


Insects diversified and occupied every environment in the world. I named the arrival of the insects the primal phase. Just like the insects in the primal phase, mammals emerged in every environment, in the air, water and on land and the appearance of the mammals I call the concluding phase. The phase of life between the insects and the arrival of the mammals is the intermediate phase.


The animals in these three phases can be distinguished by the manner of reproduction and parental care towards their offspring. Organisms in the insect world are generally unconcerned about their offspring and after reproduction or laying their eggs, abandon them. As evolution progresses there is a notable shift in the manner of reproduction and care towards the young by the parents. The offspring of mammals develop in utero and the parents feed their young and protect them. The intermediate phase shows progressive phases of greater care by organisms towards their offspring.
