The information content in DNA Language is complex, when you consider how many different words there are in English or any other language. Language can be complex partly because the human voice in complex, and any language has to contain a lot of letters or letter combination to mimic those sounds. Protein coding might be about as complex as language, given that there are about 20 amino acids to choose from. Computers can carry extraordinary amounts of information. 4 times as information-packed as a computer.
Information is therefore tightly packed and can be enormous.
The eye, which is perhaps the most complex organ in the body, apart from the brain. But start with a simple spot that at first can distinguish only light and dark. There's a difference between add-on technology and engineering. An engineer can start from zero and design a machine to do a job. An add-on technologist takes an existing machine and modifies it by adding new bits, and sometimes discarding old ones.
