Here is my take on the evolution of life on Earth. I skip over the difficult issue of the design of DNA and RNA. There are some moderately plausible proposals for that. I rely not on computability theory but information theory. The information in our genes represents a sort of investment that evolution has made.

With DNA at center stage we know of several failure modes of copying DNA. One of these involves duplicating stretches of DNA which in subsequent generations evolve independently to solve different real problems. To compensate for this we measure the evolutionary investment by the size of compressed DNA in the sense of information compression. This counts the duplication as a small step, but grows significantly as the copies go on to solve different problems. Someone has proposed that there remain 5 copies of the DNA that makes Hemoglobin that have split off in the ancestors of the primates. Three copies are defunct. One has specialized in the sort of hemoglobin necessary before birth. Some probably served for a few megayears to provide options in case of environmental contingencies. Counting compressed DNA info will include a lot of noise which should not be counted. Counting the compressed form of the conserved DNA might be a good measure. I am amazed at how small this number is for the human genome. There are much larger programming projects.
