95M-Year-Old Octopus Fossils Discovered

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

[jollyreaper]

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! And just what have you accomplished, Mr. Eight Arms and no Endo-Skeleton? You just float around and let them turn you into seafood. I'm leaving you for squid! He's got backbone for an invertebrate! At least he's capable of taking out some air-breathers every now and then!"

What a remarkably obtuse thing to say. How can anyone know -- short of subjective observations, which are inherently non-scientific, i.e. revelation from such an "evolution-motivating" intelligence -- whether or not there is an intelligent motive behind any such process?

Look, if you want to ridicule the "creationists" and "intelligent design" proponents, just have the balls to come out and say it; don't pussyfoot around, trying to be clever. Or, better yet, just keep your bigotry to yourself.

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

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.

Land vs. Sea evolution

[Saffaya]

The remark about sharks and octopods not having evolved in millions of years, compared to all the evolutions witnessed on land, make me wonder if it is caused by the oceans being a more stable environment across the eons than land ?

I mean, look at the coelancanth : living fossil. Do we have anything as ancient on solid ground ?
Or is land intrisincally a much more dynamic/chaotic/subject to wild changes ecosystem ?

And you can build great sentences, with the same word six times in a row:

"Wenn hinter Fliegen Fliegen fleigen, Fliegen fliegen Fliegen nach." (When flies fly behind flies, flies fly after flies)

Sure, and you can do that in english too:

Wouldn't the sentence "I want to put a hyphen between the words Fish and and and and and Chips in my 'Fish and Chips' sign" have been clearer if quotation marks had been placed before Fish, and between Fish and and, and and and and, and and and and, and and and and, and and and and, and and and Chips, as well as after Chips?
