Fine tuning/ programming

Descent with modification from less 'intricate' systems.After all, the basic invertebrate 'heart' is a simple muscular tube which moves blood-like liquid by peristaltic contraction. Muscle sections working in a timed, sequenced, manner.The fish heart with its two chambers may seem more complex, but it's still effectively a muscular tube with one part contracting followed (offset in time) by the next part contracting. The change of architecture doesn't seem to have required very much change in the 'programming'. First, because it doesn't seem at all necessary.Second, because I've seen no evidence as to how/where/when such a 'someone' COULD have accomplished such a thing. Before considering such 'programming' by a 'someone' as the probable explanation, I would want some indication that such 'programming' by a 'someone' is at all possible, at least in principle.

Your imagination. There is no programming.All that was necessary was that it 'worked' in preceding organisms and their type of usage.From that most simple tube of muscle where one section reacted a certain time after a previous section to accomplish circulation (even THIS case is 'intricate' according to your given definition) that sequencing you seem so impressed with is already working.So, now, tell me how it might BE programming.'It looks like it' is a very poor rationale.What cases of such programming having been 'installed' within, actually built into, working living systems can you unambiguously identify? How and when was this installation accomplished?

It's generally associated with the 'argument from ignorance':Argument from ignorance - Wikipedia(and the 'argument from personal incredulity is included on that page)

quote:

---

Commonly in an argument from personal incredulity or argument from ignorance, the speaker considers or asserts that something is false, implausible, or not obvious to them personally and attempts to use this gap in knowledge as "evidence" in favor of an alternative view of his or her choice. Examples of these fallacies are often found in statements of opinion which begin: "It is hard to see how...," "I cannot understand how...," or "it is obvious that..." (if "obvious" is being used to introduce a conclusion rather than specific evidence in support of a particular view).

In this case, Dr. Sing is taking the 'It is obvious that...' course to claim the existence of 'programming'.
