This is a common misapplication of the principle of entropy.
The remarks were in reference to the effect of random activity on DNA. The claim by evolutionary theory is that it can add information to the genome. But, random changes that occur at a molecular level due to physical properties alone and not organized by an organizing external agency, are universally destructive.
Forgive the pun but you may be closing in on what I’m saying. There is an order to a living organism that makes it a system existing in relation to a larger system in which it participates. That organizing principle is the soul, eternal and rational in mankind, created by God.
You cannot consider the plant in isolation
I would think you have to consider the plant in isolation, as a closed sysytem in itself as you stated above, but as it exists in relation to the sun. Such is the relational nature of any soul.
It is not about organization or fuzzy concepts of complexity.
I’m trying to keep it simple so we can both know what we are talking about. I’m sorry you have to resort to disparaging adjectives.
But, let’s put complexity or order on a back burner for now, and ramp up the conversation a notch; let’s think of an example - a room full of air. The particles are flying around in every which direction with different and changing velocities. At any given time, they will have a particular distribution in the room. The number of possible distributions, aka microstates is the measure of its entropy.
Now let’s imagine a living cell, with its much more fixed structure. The number of possible locations for its constituent molecules and their energies is constrained by the structure that is maintained by its living physiology. Its entropy is low. It is more ordered and that order is more complex than that of a similarly sized drop of disorganized organic molecules. It has fewer microstates and lower entropy.
In order for the soup of carbon-based simple molecules to come together to bring about the very complex molecules required to them go on and make them work together harmoniously as they do in a cell, requires a massive decrease in entropy, which can only be accomplished by the action of an external intelligent agency. A cell is not a specific form into which a mixture of organic molecules will organize themselves spontaneously.
There is no such law in physics that says the shoes in your closet must always tend to get separated, or that crystal lattice structures must always become less crystalline.
Whoosh! Right over my head. I have no idea what you are getting at.
Shoe laces will decay, they don’t untie.
And crystalline structures must be acted upon by the physical forces around them to cause a change. I would think that this more supports the claim that random change does not make things more organized or more complex - it breaks things up.
