It's pretty certian that photosynthesis devloped after chemo-synthesis. No way to know for sure but it's much easier for organisms to obtain energy from chemo-synthesis than photosynthesis. It is certain that life first subisisted on excess chemical energy from within the earth. Hydrocarbons welling up from within the Earth were reletively easy to combine with sulfates of various metals and other chemicals to obtain energy. Photosynthesis is a more sophisticated process and would have taken more time to come about, it probably wouldn't have been first.

The word evolve means to make more complex. Evolution can go both ways. That was an ambiguous choice of words. Take a poll among layman and you will see. In this case, the choice of words gives an advantage, since it doesn't reveal the whole story which could seem illogical to many.

The use of id instead when ID is not an advantage. It starts you with two strikes against you. It makes things harder. Just saying or suggesting "id" bogs the discussion at the political angle. It is easy to discredit with nothing more name calling. Maybe making life harder is not very intelligent. But I think in terms of literally meaning an intelligent set of principles beyond selective advantage. For example, an energy balance makes sense. Dice are symmetrical so energy is not suppose to make any difference. But we don't have atomic symmetry in life molecules, reactions and configurations, in terms of all things having equal energy so we can just throw the dice.

using the word "intelligence" will ALWAYS beg the question:

"What or Who is the possessor of this "intelligence" you speak of?"

Inanimate objects cannot be intelligent--like the dice. Even if the operation of throwing dice "makes sense" to you (you being the possessor of intelligence) it's just messy and confusing to try even in a metaphorical way to describe the operation of the dice as the thing possessing the intelligence.

Actually, no:

Unless qualified by "as it refers to the theory of Evolution" I don't think you'll find any definitions that imply "complexity" and even when referring to Evolution, there's little that invokes "increasing complexity" as opposed to simple "change."

I think the important thing to realize is that ID is a bundle of somewhat random elements that have historically (well, history of ID being about 5 years at this point) been brought to bear with the goal of "refuting Evolution." Whether that's fair to any of the individual elements is somewhat moot at this point, and I think it behooves any of those elements to try to stand on their own.

The concept of id on the other hand is quite vague and as long as its printed with qualifiers and prefacing remarks about it, can be subject to further clarification without the baggage, but that depends on the skill of the presenter....

Anyone who tries to make a distinction between education and entertainment doesn't know the first thing about either,

What critics of critics of neo-creationists get wrong: a reply to Gordy Slack - The Panda's Thumb

If we lived in a world where it actually looked like the first living things were as complex or more complex than life today, or where the last common ancestor contained absolutely no evidence of an evolutionary history, or where big obvious puzzles like the interdependency of DNA/RNA/protein had no hint of solution, or where the building blocks of life were completely unrelated to those produced in prebiotic experiments – all of these things would be true, say, on a robotic planet without microscopic life, where robots were replicated by macroscopic assembly performed by other robots, and powered by hooking up to a grid of fusion-fueled power plants – then we could say “science is still in the dark” on the origin of this robotic biosphere. But instead, we have numerous lines of evidence all pointing towards the notion that current life descends from a relatively simple ancestor, and that ancestor descends from a series of even simpler ancestors. Why should any of this evidence exist, if life was poofed into existence all in one step, which is what the creationists/IDers think happened even when they won’t admit it, because they are not brave enough to defend what they actually think? Additionally, why should the remaining puzzles, particularly about the origin of the first replicator, cause any unusual amount of discomfort for scientists? Whether or not that puzzle is solved, the gap between prebiotic experiments and the first replicators (or better yet, pseudoreplicators with statistical inheritance) is a drastically reduced vestige of a gap compared to what the gap looked like in, say, 1950. When you think about it, the creationists’ attempt to insert miraculous divine intervention into this tight little gap which is left is actually pitiful, and a pretty sad commentary on the state that creationism/ID has been reduced to. The verse “And God said, let the NA precursors link together into a short noncoding kinetically favored chain and pseudoreplicate approximately statistically after their kind” just doesn’t have the same ring to it.

If anyone has any doubts about the state of OOL science, read the above pandas thumb article.

PZ Myers also responded to the article:
Pharyngula: What is wrong with journalists?


I also personally think Directed Panspermia(referred to as "intelligent design" in previous posts itt) is a very unlikely scenario for two reasons. One, the technology that would be needed for such a process would require a lot of time and resources, and two, I agree with Stephen Hawking when he says primitive life is probably common in the universe, while intelligent life is probably fairly rare. Given the lack of evidence for Directed Panspermia, and what we know about the last universal common ancestor and the prebiotic conditions of Earth(see pandasthumb article above), life forming here independently (or with help via undirected exogenesis/panspermia) is much more likely.

Also, Intelligent Design has a very specific definition, and was coined by Christians with a very specific agenda:

Intelligent design - Wikipedia, the free encyclopedia
Intelligent design is the assertion that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection."[1][2] It is a modern form of the traditional teleological argument for the existence of God that avoids specifying the nature or identity of the designer.[3] The idea was developed by a group of American creationists who reformulated their argument in the creation-evolution controversy to circumvent court rulings that prohibit the teaching of creationism as science.[4][5][6]

The only group other than Abrahamic Theists(mainly Christians from The Discovery Institute) that subscribe to ID would be Raelians:

Raëlism - Wikipedia, the free encyclopedia
Raëlism, or The Raëlian movement, is a UFO religion founded by a former French sports-car journalist and test driver named Claude Vorilhon. Raëlians believe that Vorilhon, who is known by the movement as Raël, received special knowledge and instruction for mankind from the creators of life on Earth, human-like extraterrestrials called Elohim whose technology enabled them to appear as "angels" or "gods" in the eyes of ancient people. Raëlians believe that previous visitation from Elohim sparked the founding of many major religions humanity knows today.[1]
[...]
Raëlians believe that all life on Earth, humans included, was created scientifically by human-like extra terrestrials that are more scientifically advanced than us, called the Elohim, using DNA synthesis and genetic engineering and thus believe in intelligent design. Throughout the ages, Elohim sent different prophets: Moses, Jesus, Buddha, and many others to guide humanity and to prepare us for the future. Largely left to progress on our own, until the time of the Apocalypse/Revelation when Elohim would send their final messenger and reveal the truth for all to know. Raëlians desire to spread that message and work towards building an Embassy where we can officially welcome the Elohim back, and for the first time in human history, actually understand them for who they are, instead of worshiping them as gods as our primitive ancestors did.[5]

Wowee kazowee, Batman!
Thank you for pointing out this critical review. Excellent.
Okay, so the Creationists didn't get anything right.
That seems to be par for their course.

If you look at fossil data, logic says the fossils that are most likely to be found will stem from species or animals with the most units. If one animal has 10,000 units and another only 10 units, the odds will higher us to find fossils of the first scenario. This is common sense but it can be supported with statistics and experiment that uses 10,000 red blocks and 10 blue block in a box. We will pick 50 units.

We don't find as many missing links, simple because there may not have been many units. It doesn't mean they didn't exist, only the fossil data will not reflect them since the data is biased toward higher population animals with more units. There is nothing wrong with this, with selective advantage being a good theory to reflect the advantage of those species with more units.

With science, theory needs to reflect the data. If the fossil data is biased by population of units, the theory needs to reflect this to take into consideration the preponderance of solid data. This can create a practical problem. The way I look at it, the data we have is not just a random sample of all the species that were present. The sample reflects randomness but within a bias slanted toward species with more units.

As an example, say the earth had a major catastrophe. This is hypothetical. One million years later an alien comes back to collect human fossils. One is more likely to find fossil types of humans with more units, if we assume a random fossilization and degradation of all the humans on earth. One will get more fossils of poor people than rich people. Based on this data, one may have to conclude somewhat malnourished humans had selective advantage with genetic drift going in this direction. This would be totally consistent with the hard data and evolutionary theory even if it does not reflect historical reality. But to assume this conclusion is wrong, would contradict the data.

Based on this empirical paradox, we need to add logic, if we wish to come to the reality. To get the correct answer, based on historical records the aliens find, they would have adjust the interpretation of the data. They would have to create a new theory so when we use the population biased data we get the old theory.

The analogy is special relativity works with unbiased data or any random velocity we chose. While Newtonian works within any random velocity but within the bias of slow velocity. The new theory when reduced to the biased fossil set needs to default down to evolutionary theory. The goal needs to be more logical to predict the results before they appear so the theory can use any data and does not only work with the population biased data. That is my thinking which made we wish to try other things.

HB,
I'm just guessing here, but your posts make me think that you have been raised in a family, or at least in a local social culture (possibly a church) that has gone to some lengths to raise you to believe that evolution is more or less bogus. Reminds me of my upbringing.

Anyway, I say this because of the little things in your posts that keep showing up, like the way you use simple scientific terms, like "evolve" or "complexity" -- much like the ways that creationists insist on using these terms.

Creationists are purposeful in crafting their own definitions for these scientific terms and in persuading folks that these are the "real" definitions. So, you might find it interesting to take an hour off, get a college dictionary, put your feet up, and check out the meanings of a dozen or so terms used frequently in evolution.

There's an old saying I just discovered:
If a Creationist tells you the sky is blue, go outside and check for yourself.

By all means, correct me if I'm wrong.
cheers
