bio evolution, light, sound and aroma

Natural selection cannot "know" anything. Natural selection is simply the name given to the process whereby those most critters most likely to survive and reproduce like organisms end up constituting the population over time.As for how senses developed, let's take hearing. Sound is simply a pressure wave oscillation transmitted to the atmosphere. Every organism, including those which are completely deaf, is sensitive to pressure of some magnitude. But those organisms with more sensitivity can determine more about their surroundings so that they are more likely to find food and avoid being eaten.Assigning human characteristics to something you don't understand invariably leads to muddled thinking. In this case, goofy anthropomorphization seems to be the complete basis for even asking the question. Part of the process of evolution is the introduction of random variations. It turns out that random variation selected by natural processes can produce results of exactly the type you ask about here.

I think AndrewPD is correct on this point. Science does not have a way to identify design in nature. That truism is one reason why ID is not science. In fact none of the stuff advocated by Andrew PD is science. AndrewPD asserts that design, intelligence, and meaning are present in nature. He then backs up that assertion with bad arguments.What you've described here is how we identify artifacts made by humans. In fact your process for identification explicitly requires features that do not occur naturally.

We can also note the two heads on that united body. Surely you saw that too? For which side are you arguing here?Edited by NoNukes, : No reason given.
