1) What specific facts are you referring to, that scientists used to back up their hypothesis concerning the macroevolution of any species? Use any example you want.Quote from deltastrike:
Well, let's dig into this...
First of all, that's not how science works. In the scientific field generally there is a hypothesis, from a scientist, proposed based on previous knowledge/facts. In most cases the hypothesis is an extrapolation of what's known, and scientists use experimentation to prove their hypothesis one way or the other. Scientists actually welcome negative outcomes as information is obtained regardless.

2) What specific hypothesis, concerning macroevolution, are you reffering to that has been proven? Again, use any example you want.
Yes, deltastrike, I' ve read over those webpages many times before.Quote from deltastrike:

"There is plenty of science to show how life can come from non life."
Quote from jem
For years you said we had proof that life came from non life.
You see, you can't reason. It's why you're forever arguing like a red neck creationist.
The first statement is mine and it's true.
The second is yours, which you changed in this thread by adding the words "or evidence".
At least in its original form the second is a blatent lie, now its .... well...still a lie.
Then science doesn't have enough info to rule out Odin, Goblins, Spiderman or the Speghetti Monster in that case. But what use is that to anyone? It isn't science.
Now true to form you've started re-repeating and cycling through like a thoughtless troll, more of your same old cut & pastes that have already been refuted debunked a thousand times. Well done.
pathetic.
I have decided to name what I am seeing more and more of from you..
u.b.s.
utter bull shit.

"The constant gardener
One problem is that, as it stands, the model requires its 20 or so constants to be exactly what they are to an uncomfortable 32 decimal places. Insert different values and the upshot is nonsensical predictions, like phenomena occurring with a likelihood of more than 100%.
Nature could, of course, turn out to be this fastidious. But physicists have learned to take the need for such fine-tuning, as the precision fiddling is known in the argot, as a sign that something important is missing from their picture of the world."

In fact if one does adopt a bottom-up approach to cosmology, one is immediately led to an essentially classical framework, in which one loses all ability to explain cosmologyâs central question - why our universe is the way it is. In particular a bottom-up approach to cosmology either requires one to postulate an initial state of the universe that is carefully fine-tuned [10] - as if prescribed by an outside agency or it requires one to invoke the notion of eternal inflation [11], which prevents one from predicting what a typical observer would see.

âIf there is only one universe,â British cosmologist Bernard Carr says, âyou might have to have a fine-tuner. If you donât want God, youâd better have a multiverse.â (Discover, December 2008)

Summary...
I have provided dozens of quotes and videos from other top scientists.
so given our current understanding it is widely and almost universally accepted that our universe appears fine tuned.
The question is what the explanation...
given what science understands now...
a. we really are incredibly fine tuned because there is a Tuner; or
b. perhaps there are almost infinite other universes... so our is not so special. (note this is pure speculation.)
c. we will someday find a reason why our constants are so tuned.... via a theory of everything...(although... then the question might still be... does it take a tuner.
d. there are a very small number of scientists who do not buy into the fine tunings..... but I will bet that with the finding of the higgs boson... there are even fewer.
Quote from futurecurrents:
I mean, how does a butterfly do it? A tiny computer with eyes and chemical sensors and wings and an engine, weighs a few grams, navigates and flies thousands of miles. Can zip through a thick forest without hitting things. Amazing. That natural forces and time alone can design such thing boggles the mind and makes even the most hardened atheist wonder.
Quote from stu:
If I understand your point I think it might be an academic one. The current common ancestors of all living things, bacteria / eukaryote / archaea may indeed have had multiple forbear lineages. There may well be many organisms preceding those ones, but at that level of molecular science, would it not be pure chemical reaction which is the precursor to the origin of life?
Inorganic chemicals reacting in numerous different ways, forming simple evolving self-replicating organic molecules in chains of nucleotides to RNA . From multiple root form origins, but essentially one common origin.
The actual detailed processes being another kettle of fish, but the origin of all life - I would suggest is basically a chemical one in any case.
With his one answer to all questions, goddidit, that's must be pretty much true.
