It is not an answer as it fail to explain why chlorophyll is used to extract energy as opposed to any number of chemicals.
The evolutionary reason is that chlorophyll evolved first and was adequate.

For someone who doesn't have time for a lengthy post you sure spend alot of time online....
You wouldn't be avoiding posting your ideas, would you?
What makes you say that? Man has been "engineering" plants for more than 3000 years through selective cultivation. It's the reason why modern, domesticated grain plants produce much more food than their original, wild ancestors. :shrug:
edit: Oops...Arthur beat me to it.
One of the ways modern archeologists determine when a particular region made the transition to the Neolithic Era (farming and permanent settlements instead of nomadic hunter-gatherers) is to check the DNA of the plant tissue in their middens (trash heaps). If it's been hybridized, that's the sign of cultivation. Just a few years ago they found the very first hybridized crop, and to everyone's surprise it was figs! In the New World it was peppers, a little later than Mesopotamia.Laugh all you want, but almost all the plant food we eat today has been "engineered" by humans.
Considering that corn (maize) is one of the least nutritious grains, that's not saying very much! That may be one of the things that slowed the development of civilization in the Americas. Not enough protein.Modern Corn . . . . significantly different and far more productive then the original natural versions.

Man is pouring his food in the gas tank, I don't think he is as smart as you think he is.
Man has not been around for that long.
You are basing your views on a short period of time.
Climate stability is (was) a big issue as well. Mostly thinking about ENSO. There's "evidence to suggest" periods of massive el nino/la nina oscillations that dwarf anything we've seen in the last 50 years, including, I believe, some annecdotal evidence out of Africa (things such as the Nile being reduced to a muddy swamp). Europe has the advantage of being somewhat insulated from the effects of ENSO, however.Considering that corn (maize) is one of the least nutritious grains, that's not saying very much!

Well, that and no large herbivores to turn into draft animals. If Aztec civilization had spread to North America they might have tried domesticating the bison. Can't be any harder than elephants! Surprisingly, the Inuit did not domesticate the caribou. The people they left behind in Arctic Eurasia domesticated the reindeer, which is the same species. But that's no city-building beast of burden, only about as big as the llama.
I'm still waiting for a substantive response to either of my posts (heh, bit of rewording and some inline sources, they could almost qualify as essays).No, he saves time by not using his spell checker.

Hey esbo, please tell me that was a typo!
Did you come here to human bash ? Is that it ? You have a disdain for people so you come to condemn the human race and the color of plants has nothing to do with it ? Look bro we are your friends not your enemy. We all want a better world too . Your not a lone in this
I don't think he meant that man has been around for less than 3000 years...but was just stating that we haven't been around that long in comparison to how long plants have been around. At least..that what I think he was saying. Even "young Earth" creationists believe that man has been around some 6-8 thousand years.
Well I came here to ask a question and discuss it.
I just made a comment. People are suggesting that engineering is better than nature. There is not a great deal of evidence to support that idea.
But it goes back another comment or idea that plants being green was some sort of mistake, that nature 'cocked it up'. That is highly unlikely IMO.
And the human race ha sit's failings, there is no denying that, if you want to call my pointing it out 'bashing' then fair enough. Man usually comes to his senses eventually but all to often at great cost.
I am just pointing out the craziness of man's engineering 'solution' to lack of fossil fuel, ie biofuel, one of the maddest idea man has ever dreamt up.

I am not discounting the possibly man has only been around for a few thousand years, I was not there so I can't be sure.
Just read this entire thread. Some excellent data from Trippy, Fraggle and others. Still waiting for Esbo to actually address the problems he has with the answers given to his question. Lets get to it, shall we?
Problem is most of the answers are just going into the detail of something which is irrelevant, that's why I did reply mean, I mean their theories seem to be based on the idea that evolution stopped.
I hope you can see how crazy that is and it is a pain to go through the examples where evolutions stopped for the obvious reason that evolution has not stopped.
It's just crazy basically. :fright:
Really?
A few thousand years?
