that is a good example of intelligent design, but all you ever hear are vain unverifiable explanations like this
You call it an unverifiable explanation as a derogatory term, then in the same exact sentence say it is a good example of intelligent design? Are you not sensing the irony here?
i am dumbfounded that people are able to believe this type of NS without question[/quote]
Some people believe things without question. The scientists and evolutionary biologists who are working in this field will not accept anything without question; they want evidence that these insects evolved a certain way. I would as well.
, first off how does the organism even know to turn into a leaf for protection in the first place?, how does it even know that leaves exist or what they look like ,to be able to turn into one?
Ok, look. This is really simple. Here are the steps that this would take. Please read this through, this is really easy to understand. I mean, the entire thing. Read it all before you reply to it. You should probably even read it twice.
Step 1. A single specimen of an insect has a random mutation (yes, these mutations are random. It is important for you to understad which parts of evolution are random and which are not)
2. This mutation causes the insect's exoskeleton to be tinged a
greenish colour. So, a colour change. A simple, one step act of evolution. We now have a
green insect.
3. This insect is living in en environment where
green things are harder to see; say, tree leaves. This insect lives in the trees.
4. Because it has become, with its mutation, a little bit harder to see by predators than it's comrades (the other insects of its species that are still, say,
black), it follows logically that this specific
green insect would have a higher chance of survival than it's brothers, who are
black, and easily seen by predators.
5. The
green insect lives on to reproduce. It mates with another insect of its species and their offspring are also
green, like it was.
6. Rememberr that in their environment, it and its offspring (say, 10 new
green insects) are the only
green insects in this species. As they live safely in the trees, difficult to see by predators, they watch as their
black brothers are dying around them, being eaten by the predators that can easily see their
black bodies against the
green leaves.
7. Soon, as the
green insect's offspring reproduce, there are many more
green insects. Say, a thousand
green insects. Meanwhile, less and less
black insects are reproducing because they are being eaten. While the number of
black insects slowly goes down due to being eaten by predators and less rate of reproduction, the
green insects flourish. Sure, a few specimens die here and there, but there are still many many
green insects living in the trees.
8. Fast forward to 2 years later. The amount of
black insects is, if not already completely gone, very, very low. The last of them are being killed by predators who can easily see them.
9. There have been more and more
green insects living in the trees and each new generation is reproducing. Because they are not easily seen, they live on, and their chance of reproduction rises.
10. The last
black insect is eaten. Now the
black strain of this particular species of insect is all but extinct. It used to be all
black, but
now it is all
green.
You have now seen how a population of once entirely black insects can become, in a short period of time (2 years, with insects is probably too long a period of time), a population of entirely green insects.
You may be wondering, "Yeah sure, but those leaf bugs have little veins and stuff on them too."
And I would reply to you, the same process as above will have been used. In a single creature, a mutation occurs, and that single creature is now diferent than all of the others. If it goeson to reproduce, its offpsring will have its mutation as well. If this mutation is at all beneficial, then its offspring will have a larger chance, however small, of reproducing than the general popualtion. This is what is called natural selection. The insects' situations selects those insects with a higher chance of surviving, and those insects will, in time, become the majority.
And one will again gain a mutation, and the process starts all over again.
The only way this process cannot happen, is if creatures do not have muattions, which is demonstrably untrue. Mutations happen all of the time. The above scenario happens all of the time, and that is what evolution is.
the only answer youll get to a question like that is, " der evolution doesnt have to know what it is doing" im still waiting for an answer to the question of where the genetic information comes from in the first place,
And the answer is correct. No, creatures have no knowledge, evolution has no knowledge, of what it will become, because evolution is not an entity, it is simply what happens when beneficial mutations are passed onto the next generations.
I understand that people often talk of evolution as if it is some sort of being or force that can control and decide what happens to thigs; of course, that view of evolution is ridiculous. Unfortunately, many people hold it.
