This is where things dont make sense. I believe in evolution, but no ones thought about this: development of senses. Now every1 knows that characteristics r evolved from existing dna material, for inst u cant just grow taller because it will help u b good at basketball & make money to live, but rather 1 ant out of 100 is resistant gene to pesticide & survives w offspring w that gene. THats how it works. It has been found that an ancient g-protein is found to allow some senses in bacteria, but research is recent. Sound is something is considerd obvious, but who woulda thought sound waves exist, & an eardrum locates some, but not all sound frequencies. It is not possible that in evolution an animals genes realized sound waves existed & needed to make something to hear it, it doesnt work that way. & if 1 by 1, hearing, seeing, feeling, smelling, tasting, came to be, then there must be things we dont know about right? more senses that just havent been evolved for us yet. is that right?

The nervous system evolved right along with animals. Prehistoric creatures did not have a well developed sense of sound vibrations. This evolved over millions of years because it was advantageous. It gave the animals that possessed a keener sense of sound detection an advantage over the others. This is true for sight as well. And i can say that just as not all frequencies can be appreciated by the human ear, not all wavelengths of light can be appreciated by the human eye. Also, dogs can hear frequencies humans can't because at some point it became advantageous to them and not to us. It is the same for smell. Dogs can smell odors thousands of time fainter than humans can because that was an evolutionary advantage that was important in the evolution of canines. For humans, when a woman becomes pregnant, her sense of smell becomes more acute during the pregnancy. This is an evolutionary advantage because you don't want a pregnant woman eating half-spoiled meat or certain plants (vegetables, etc) that can be harmful to the developing fetus. Or drinking water that is contaminated.

It is possible that at some point in the future, humans or another species will develop certain senses that are not present now because it will supply a distinct evolutionary advantage. This will likely take thousands of years or more.

Another example would be that sharks have a strong sense for magnetic fields. It can detect the magnetic field of a fish hinding under the sand. It will track it, zoom in and eat the fish. Most other animals do not have this sense because it wasn;t an evolutionary advantage.

First of all, like others, I am not convinced that evolution is a fact. However, I think that you're right, there could be other things out there for us to sense that we do not have the receptors to sense them. Look at sharks, they sense in many different ways than we do. It'd be cool to have gamma ray sensors or worm hole sensors now wouldn't it.

Why do I believe that there is a designer/creator/engineer of the life that we see? DNA is information. Where there is information, there has to be someone who communicated it.

Let me ask a question: If you are walking deep in the wilderness and all of a sudden you find a statue of a person in the middle of know where in the wilderness. You're not going to think, "hey, look, how interesting the way that the wind and water hit this rock and formed what looks like a person. Wow nature is just so unpredictable." No, you're going to think, who made this statue and why is it here.

Hearing probably came about thru sensitivity to motion in the water. If you didn't feel the predator it ate you. Or if you were the predator it was advantageous to sense the prey. It developed over millions of generations.

There may be things we can't sense. There are things that we know we can't sense such as UV or IR light that are there. Some animals can sense these things since it was to there advantage to sense them.

some animals have various senses that humans don't. sensitivity to ultraviolet or infrared light, polarised light, or more than three color receptors. sensitivity to magnetic and electrical fields. many animals also have stronger and more varied senses of smell. directional sound sense is achieved in vertebrates by having two ears, but many insects have directional hearing by sensing sound with small hairs instead of membranes. it may be possible to wire in extra senses to the human brain by genetic engineering - it's quite adaptable. ability to sense ionising radiation could be very helpful :)

Well, we could evolve to see inferred in the future, and our eyes should get better to see better, or, would they get short sighted to we can stare at pc screens better, lol
