Convergent Life (bio ideas)

Here is an interesting idea that suggests that all life is heading in the same direction when it comes to catabolic and anabolic processes and selection on those processes. Convergent Life

Convergent life.

This is an idea that combines two others.

First one from the biological texts:

1. Convergent evolution is the independent evolution of similar features in different species.

Combine that with one of my ideas:

2. There is a direction in evolution toward better catabolic and anabolic processes. [Catabolic and anabolic chemical processes evolved but did not blend.
When there is a mutation on either catabolic or anabolic processes, there is selection pressure on the other to match the good mutation, or mitigate the bad one.]

3. Convergent LIfe (or convergent catabolic and anabolic processes)

That suggest to me that in any similar environment, all life will converge on the best catabolic and anabolic processes.
OR
natural selection will always select similar catabolic and anabolic processes for similar environments.
