mmmscience writes "A new study published in Paleontology is a truly terrific find. Not only did a group of European scientists find a fossilized octopus, they found five complete fossils that show all eight legs in great detail, including a ghost of the characteristic suckers. The discovery of the 95-million-year-old specimens was made in Lebanon. 'What is truly astonishing to the scientists is how similar these ancient creatures are to their modern-day counterparts. Dirk Fuchs, lead author on the study stated, "These things are 95 million years old, yet one of the fossils is almost indistinguishable from living species."'"

selection pressures (Score:5, Interesting)
It's funny how some creatures are under such pressures they rapidly develop and others have settled into their niche so well there's been little change, thus the living fossils. It's amazing to think that the ancestors of today's megafauna were little shrew-like nothings back then and were able to progress from that to elephants and rhinos and, hell, human beings while octopi and sharks are just tooling around looking pretty much the same.
I know that there's no intelligent motive behind evolution, it is an impersonal process of optimization for a set of conditions and there's no selection bias for complexity, as we humans would view such things. It seems like the living fossils are stuck in a rut but as far as evolution is concerned, it's not concerned. There's no personified mind involved, nature is not a guiding intelligence, it's just genes playing along according to rules, rules. Still, I can't help feeling octopi's wife is nagging him "For crimminy's sake, just look at you! 95 million years and you're still mucking about on the ocean floor! There's an entire world out there of land dwellers! Those little shrews went and developed opposable thumbs and they're running the place!

I'm sorry, I must have missed your point amongst the sarcasm.
I understand. All the magical thinking must make it difficult to understand things like "facts" and "theories". Here, let me explain for you the nuances of my post as simply as I can:
1) Attacking magical thinking (intelligent design, etc) as being unscientific is not bigoted. It's simply the truth. Live with it.
2) Christians, Flat-Earthers, the poor Flying Spaghetti Monster adherents, none of them are downtrodden minorities being attacked by an evil establishment. Ditch the victim complex and move on.
Additional points that I didn't make, but seem worth mentioning now, include:
3) Hypothesis that can never be disproven are unscientific, are not theories, and are of precisely zero (0) value. If the hypothesis can't be tested in the real world, then it can't affect the real world, and so it is useless.
4) Russell's Teapot [wikipedia.org]. It's not my job to disprove your outlandish claims. It's your job to provide evidence to support them.
5) As a corollary to #4, given no one has demonstrated evidence of "intelligent motivation behind evolution", it would be irrational to believe otherwise. Similarly, I don't believe aliens have abducted humans, that homeopathic therapy is anything but a fancy placebo, or that thimerosol causes autism.
Is there anything else I can clear up for you, or does that answer your question?

That exactly -- EXACTLY -- as probable as whatever 'intelligent design' you're advocating, whether it be the Egyption Ra controlling the universe, Zeus, or the Abrahamic God.
In other words, no one can be sure what's "really" going on. But what we do know is that evolution can actually be observed, has been observed, and will be observed again (including new species creation). The Christian God or Pink Elephants both have the same amount of observed evidence.

Please provide a theory explaining the existence of a creator god or gods and the methods used by them in the creation of the earth and the means to prove such a theory and the scientific community will be forever in your debt.
Barring such evidence, we are left with saying "we see no evidence for an external creator, no evidence of a guiding intelligence in evolution; what we can observe can be explained by evolutionary theory and any gaps currently present in our knowledge are avenues for further research." Science looks for the best theory at hand, not the perfect one that explains every little detail since such a perfect theory is hard to come by. We may not know everything there is to know about electro-magnetism but what we do know of it allows us to make computers work which is somewhat better than the view the ancients had of lightning, i.e. thunderbolts thrown by the Zeus.
Science cannot definitively prove something does not exist but it can at least reduce the question to an irrelevance. Consider Russell's Teapot.
http://en.wikipedia.org/wiki/Russell's_teapot [wikipedia.org]
If I were to suggest that between the Earth and Mars there is a china teapot revolving about the sun in an elliptical orbit, nobody would be able to disprove my assertion provided I were careful to add that the teapot is too small to be revealed even by our most powerful telescopes. But if I were to go on to say that, since my assertion cannot be disproved, it is an intolerable presumption on the part of human reason to doubt it, I should rightly be thought to be talking nonsense. If, however, the existence of such a teapot were affirmed in ancient books, taught as the sacred truth every Sunday, and instilled into the minds of children at school, hesitation to believe in its existence would become a mark of eccentricity and entitle the doubter to the attentions of the psychiatrist in an enlightened age or of the Inquisitor in an earlier time.
But since you think I'm being clever, here's another one: Don't pray in my school and I won't think in your church.

Evolution requires environmental pressure in order to allow changes to be selected. If there isn't much of an environmental pressure outside of being faster than what's trying to eat you or smarter than what you're trying to eat, there won't be much evolution except to these ends.

Sensory and intelligence apparatus can change a great deal while a creature superficially remains the same. There may be others (e.g. efficiency), but those are the ones I immediately think of. I suspect those things are harder to get right, so they take longer for natural selection to do its thing.
Consider a mould of Isaac Newton versus early man. Newton's head was a bit bigger and his body a bit weedier, but all in all, pretty similar. Or perhaps more to the point, consider a WWII or 1950s submarine versus the latest iterations of US submarines, or an F-22A versus an F-15 or F-18. Superficially they are very similar, because an object that spends all its time in a fluid will need to be designed (or will converge on a "design" through natural selection) to move efficiently in that fluid.
However, the power plant, avionics, stealthiness of later iterations of military vehicles are going to outclass earlier vehicles by a huge degree. Pitted head to head, the former submarines and aircraft will only be capable of lucky kills. Getting back to the example of the octopus, we have no way of knowing whether the earlier version of octopus could change color at will, spurt ink, or figure out how to get food out of a bottle with a cork in the top.
