Cofty - your condescending comments without an ability to answer the question imply that you do not know the answer and trying to divert that lack of knowledge to me. Why don't you read some 'basic' (elementary, grade school books, implying you are an idiot) yourself and then perhaps you can explain, defend, and answer the question instead of trying to close the argument by having me do the research that you yourself are unwilling to do.

One aspect of evolution that does not make sense.....
by EndofMysteries inthe part that does make sense are how bodies adapt over time to surroundings and use.
for example because of eating habits changing, our jaws have become smaller and we don't need wisdom teeth.
or the effect of the sun on our skin, etc.

apognophos - my theory assuming the species are the same is that the chameleons are comfortable w/ their human handlers so their color changes are only mood based since they don't feel the need to camouflage. That theory could be tested by presenting them w/ predators, etc, out of their comfort zone and seeing what happens.

Okay I'll accept your backing out of this debate.
What is my problem?
Okay, chart out an evolutionary process that will allow humans to camouflage exactly like chameleons do, whether it takes 1,000 years, 1 million years, or 1 billion years, without direct scientists intervention, at some point in the future a human can do what chameleons do, and it must be by evolution only.

" There is this myth that chameleons change
colour to blend in with their surroundings, but this is actually not true. " That's what your article said,,,,,my article says, "
Using a spectrometer, the team took readings of the colour shades and brightness of the background and the chameleon. Then, after the chameleon had spotted the model predator and changed colour, they took another set of readings.
The chameleons colour-matched their backgrounds much more closely when presented with a bird than a snake, the team found."
Both articles have opposite claims, my article is backed by research and study.

I read the link, as you said chameleons changing their appearence to camouflage and hide from predators is a myth, which the link and article I then posted refrutes that claim.

Chameleons' mastery of camouflage goes further than anyone expected - it seems they can fine-tune their colour changes to the visual systems of specific predators.
Devi Stuart-Fox at the University of Melbourne, Australia, and colleagues studied the Smith's dwarf chameleon (Bradypodion taeniabronchum), which lives in South Africa.
This critically endangered chameleon can alter its colour palette in milliseconds, either for camouflage or for social signalling.
The team captured eight males and eight females of the species. They placed them on a branch and presented them with realistic models of two of their biggest predators: the fiscal shrike (a bird that impales chameleons on thorns before eating them) and a venomous tree snake called the boomslang.
Bird threat
Using a spectrometer, the team took readings of the colour shades and brightness of the background and the chameleon. Then, after the chameleon had spotted the model predator and changed colour, they took another set of readings.
The chameleons colour-matched their backgrounds much more closely when presented with a bird than a snake, the team found.
However, when the team modelled the visual systems of both predators, they found that the chameleon still appeared better camouflaged to the snake than the bird, thanks to the snake's relatively poor colour vision. In the presence of a snake, it seems, the chameleons just don't have to try as hard.
Subtle changes
The researchers noticed that the chameleons were also consistently paler, compared with their background, when presented with the tree snake.
"This is probably because while birds usually approach from above, putting the chameleon against a dark background, snakes usually approach from below, putting it against a background of a light, bright sky," says Stuart-Fox.
Other animals can adjust their defensive behaviour or appearance in response to different predators.
For instance, the ground squirrel pumps more hot, infrared emitting blood into its tail
when it spots an infra-red sensing rattlesnake. But this is the first time anyone has observed an animal modifying that change to best avoid being seen. -

If that's the case cofty, then camouflage would only be coincidental if they happened to be in an area that matched what colors it changed into. Since it matches what colors are around it, then that takes away that possibility.

All of these answers seem to be assuming that by chance an organism happens to over time look like it's surroundings and so those who happen to slowly mutate into looking more like their surroundings are the ones that blend in. That can make sense for those that have just one appearance, I might buy that for a dollar.
Not for a chameleon though that changes his appearence to blend in to the surroundings and based on the type of predator looking at him.
Maybe this will answer my question, somebody explain to me before a chameleon had the ability to camouflage itself, if it was always just a brown skinned creature, explain the process of evolution and the triggers that it developed the ability to camouflage.
Cameleon generation 1 - one color, has no more ability to change it's colors and appearance then would a human be able to.
Explain how by generation 100, or 1000, etc, it can do it.
Now for something like why humans needed wisdom teeth but now they don't that would be easy to explain, but I can't think of how they would go from no ability to change color to what they do now, so perhaps if you can explain it that way, it will make sense.

The Untold Story of Creation
by mynameislame inposted on behalf of jon p. .
http://www.jw.org/en/publications/magazines/g201403/untold-story-of-creation/.
i don't find the article itself very compelling but it seems to be opening up the possibility that a creative day is not a specific time period.

No problem, if there is anything the interlinear has taught me, it's that english translators assumed what complex scriptures such as Genesis 1 were talking about and many omissions and assumptions can really change the meaning and hide what was originally being taught.
My entire understanding of the creation is changed after dissecting it in the interlinear. It makes sense and is impossible to understand and learn in any english bible.
