Semi random to be fair...not all chemicals will bond with all chemicals. Chemistry does have its set of rules.
now I don't want to go backwards to abiogenesis because you guys will get all pissed off and yell and scream about how that isn't evolution, so I won't go there.
abiogenesis is a type of evolution, but really its own separate theory. It's kind of like Newton having to explain why gravity works to get his equations accepted...it's not a necessary step. Whether life arose from a miracle of god or a gathering of physics and chemistry, it happened, and evolution takes it from there.
Lets go the other way. -------------->
We have an animal. It evolved. ------------------>
Now it's going to evolve some more until it becomes a totally new animal.....eventually. Right? -------------------->
Ok.
Macro-evolution involves trying to become some totally new animal with new organs, a new basic plan for existence, and new requirements for integration between both old and new organs.
Stop right there...micro-evolution is very small changes that happen within small periods of time, right? Stuff that doesn't change a creature enough to call it a new species. But enough small changes over a long period of time between two isolated groups will create a species rift, and an occasional fossil of this process will create a transitional fossil for us to connect the two. We're talking long times, different environmental pressures, and the dilemma of fossils not being all that common. Every creature that dies does not fossilize; few do. So we have to go by what records we find, and scientifically connect the dots. If we find that our guess is screwed up by a new fossile, we erase that line, and figure in the new data.
But new creatures don't get popped out of old creatures. Even punctuation equilibrium doesn't predict dinosaurs birthing birds....that's a creationism spin or misunderstanding of the theory, take your pick.
Take a bird for example. So you're a lizard but you need to become a bird to survive but you don't even know it. Nature is working out the details.....evolve.....evolve...evolve....--------->
Problem.
Vast majority of fossils should show intermediate stages. They don't. Solution: ?
Suppose you still aren't one yet but you're getting there. You still need to evolve many specialized body parts, including wings, flight feathers, a specialized light bone structure, specialized flow-through design heart and lungs, specialized tail, specialized general balance parameters etc.
Ok. No problem.
So the neo-Darwinian crowd (Gould and Eldredge, et al), lacking the necessary fossils to convince everyone, says this stuff happened and it happened really fast and in spurts .....this has become known as punctuated equilibrium or punk-eek.
Here's my point to this rant or rather my question. Does the lack of intermediate fossils bother any of you?
We've just found another unique fossile, more of a reptile, but with feathered legs, like a flying squirrel almost. We'll find more...why is what we have found not convincing enough that something is going on over time?
I know you'll immdeiately refer to me to a host websites like talkorigins....been there, done that, they still don't have the hard evidence, much of it is speculative in nature and the fossils they do have, the majority are based on 10% actual bones and another 90% of the artist's conception of what the animal should like.
They are a good source, but not the only one. And yes, we don't usually find complete fossils, so we have to guess on what the complete picture is. But that's not done haphazardly. In fact, such guesses are many times incorrect, so we have to go back when new data is found and redo the guess. So what, that's how science works. We certainly can't make it all up and have it 100%...what do creationists want, a perfect prophecy record for paleontology? That's not science....
Does anyone wonder why, if punk-eek is true, none of the experiments on fruitflies has produced anything but another fruitfly? Shouldn't so factual a theory as evolution have some concrete evidence that big changes can happen billions of time to millions of animals in short bursts of time and at least leave a few hundred thousand examples in the fossil record? Does this not concern anyone?
I don't know what experiments have been done with short lifetime creatures to try and simulate isolation and species splitting. And I don't think punct equi is that quick, or the best solution. Current evolution theory is a mix of the different ideas, to try and match the various explanations with what we see in the record, the current world, and lab. And as for fossils, I covered that above...fossilization requires special conditions to occur, so the chances of finding every last change down to micro-evolution changes for past creatures is unlikely.
As Ted Holden says, the conflict isn't between evolution and religion. It's between evolution and mathematics. Probability and statistics are not voodoo.
Every example I've seen of applying math to discredit evolution is used incorrectly (usually it's against abiogenesis, but anyway, still incorrectly applied). Numbers are pulled out of thin air, when in fact there are limited ways that chemistry can combine elements, there's the countering big numbers in the equations of time and area affected, and we have found evidence in the lab and space of organics somehow appearing non-biological. It's a matter of piecing it together at this point.
If you do the math using what we know of the time span, the area that was used in early earth, the chemical compounds available, how those compounds would react with each other if exposed, and the probability is calculated...it's very likely that life would have arose.
But evolution itself, after this point of life creation, is a fact...no alternate theories of why we find what we find in the fossil layers is credible, not because it comes from creationists, but because it doesn't hold up when tested scientifically. The more data is found, the harder it is to take a creationist's argument seriously.
