How does complexity manifest itself in the evolution of the universe?
Today’s Post
Last week we saw Teilhard’s first step toward understanding evolution as recognizing that its common denominator in every phase of the unfolding of the universe is ‘increase in complexity’. We saw how he sees the appearance of the cell as a specific instance of a ‘step of complexification’. As he put it, the cell is just one example of
“… the stuff of the universe reappearing once again with all its characteristics- only this time it has reached a higher rung of complexity”.
Given that the cell illustrates one step of the billions needed to grow the universe to its current complex state over fourteen billion years, how can the characteristics of complexity be seen as active in each of the steps?
This week we will review two of seven of Teilhard’s insights into how complexity can be objectively observed as a general phenomenon present in every stage of evolution.
The Cell as a Specific Example of Universal Complexification
In the ‘Phenomenon’, Teilhard lists seven characteristics of the cell that can be seen as ‘new’ when compared to its molecular ancestor.
– Thrust forward in spontaneity
– Luxuriant unleashing of fanciful creations
– Unbridled expansion
– Leap into the improbable
– Essentially new type of corpuscular grouping
– More supple and better centered organization of an unlimited number of substances
– Internal onset of a new type of conscious activity and determination
Having recognized these characteristics, we can go on to see how each can be seen as active in each and every step of universal evolution from the quark to the human person.
Thrust forward in spontaneity
The cell clearly shows an increase in spontaneity when compared to the molecular ‘replication’ process from which it emerged. With its greater potential for connectivity, the cell is now able to carry the simple molecular activity of ‘replication’ into the biological activity of ‘ramification’.
It requires the repackaging of DNA into a configuration with more potential for branching into ever more complex forms. As Richard Dawkins explains, DNA itself cannot evolve. It can only provide instructions to RNA to manufacture proteins. However, these ‘instructions’ are susceptible to occasional failures, such as seen in tissue growths induced by x-rays. The cell provides a vehicle for the modified DNA to prove its worth as it is exposed to the environment by the increased mobility of the cell.
Each new step of evolution, from the formation of atoms from electrons, proteins, and neutrons to the formation of brains from neurons, is accompanied by such an increase of functionality as well as potential for more complexity. A simple metric which illustrates this phenomenon can be seen in the increasing number of ‘new’ products that result from groupings of their fewer number of precedents. Examples include the hundred eighty types of atoms that result from groupings of their four constituent components, or the thousands of types of molecules that result from these hundred eighty atoms. The hundred million neurons in the human brain also provides quantification of this phenomenon.
Luxuriant unleashing of fanciful creations
In capitalizing on the ‘replication’ potential of DNA, the cell offers another example of complexification. Teilhard uses the word ‘fanciful’ to denote the ‘branching’ (or ‘ramification’) of biological products into ever more complex arrangements. With the increased complexity of the cell, the environment becomes radically more open to its activity. Many attempts have been made to show the staggering proliferation of biological configurations (the ‘tree of life’) that science believes to have emerged from the one or two original cellular prototypes that emerged some three or so billion years ago on this planet. Again, this can be seen to a lesser extent in ‘pre biological’ evolution (as in fabricating proteins from amino acids) and becomes even more so with the ramification seen at the other end of the biological scale: in human culture.
Next Week
This week we began a look into how Teilhard understood the action of ‘complexification’ which is active in all stages of evolution as it unfolds in the universe.
Next week we will expand this list of ‘complexification’ actions on the way to seeing them as active in the current phase of evolution, ‘thought’.
