ORIGINAL: seeksfemslave Have gone goggle eyed trying to find info. on Ammonites so I change tack and throw this atchya. http://www.skepticalinvestigations.org/controversies/Dace_evolution.htm quote:
So stupendously unlikely is the perfect mutation at the perfect time that calculating the odds against it taking place even once exceeds our imaginative capacity. It is, in fact, a miracle. Now multiply this improbability for all the useful traits belonging to more than fifty million life forms, and you see just how profoundly and irredeemably implausible neo-Darwinism really is Of course you would try this, it is one of the last creationist canards you haven't tossed out. The problem is one of point of view. The author is, amongst other mistakes, saying effectively 'look at the order of cards in this shuffled deck, the odds against it being in this precise order are so staggering that some outside agency must have placed them in that order.' But every other possible outcome is just as improbable but one must occur. A basic misuse of odds calculations and one that is fairly obvious to anyone who actually thinks about it. I will also note the author is claiming that each positive mutation must occur at just the time it is needed. Which of course is not what biologists think. quote:
An example of irredeemable implausability http://en.wikipedia.org/wiki/Sabre-toothed_cat quote:
The terms saber-toothed cat, sabertooth, and saber-toothed tiger describe numerous species, mainly in the families Felidae (subfamily Machairodontinae), Hyaenodontidae, and Nimravidae, but also including two marsupial families, that lived during various parts of the Cenozoic Era and evolved their saber toothed characteristics entirely independently with the first examples appearing at widely spead locations Europe/US at about the same time, 33 million years ago. So not only does the Delusion support the impossible it believes it can be multiplied by two. I say trying to double impossibility is equivalent to losing your virginity twice. It cant happen. lol 2 groups of closely related animals and a group already showing parraelel evolution, the marsupial carnivores, with the same basic head and teeth all developed analogous structures for feeding in a niche. That strikes you as odd? Here goes though, all the carnivora have pronounced maxillary canines. If you have a dog or cat call it over and peel back its lips. Those sharp longish teeth that kind of fit into slots in the lower jaw are the canines. Its also the pointy tooth that likely breaks the line made by the ends of your teeth in your own upper jaw. So what do carnivores do with big pointy teeth? As they are the longest teeth they reach the deepest into prey and are the teeth responsible for when a cat kills a mouse by biting it in the neck from above. Now why would some carnivores develop much larger canines? To reach even deeper into a prey animal? And why would that be helpful? Have you ever seen a film of lions taking down a cape buffalo? It's too big for them to pull it down and they can't bite it in the neck and kill it so they have to strangle it which usually leads to the buffalo dragging 3 or 4 lionesses around trying to get its horns into one before it passes out. Not a really efficient way to kill but lions don't often go for prey that big. Their ancestors would have been in the same boat. So why get the big canines? It turns out that there were lots more big mammals not that long ago. Naturally some carnivores would evolve to prey on them. As some of the prey got bigger selection split various populations of felinish carnivores. Some remained in their original niche and continued hunting prey in the size range they had hunted before but some, being selected for longer canines and an in general more robust build, specialized in bigger prey. Tellingly the teeth in the various species were slightly different shapes and lengths which is what you'd expect from this sort of process. The first sabre tooths appeared about half way into the Cenozoic, in the very latest Eocene or early Oligocene, which corresponds to the emergence of the first large herbivorous terrestrial fauna since the end of the Mesozic 65 million years ago. The last sabretooths died out just as man was becoming civilized and corresponds with the worldwide extinctions of most of the large prey species they relied upon for food. Note that there are lots of well known and well understood examples of the same character appearing in animals multiple times. Big teeth is just a big flashy example that your creationist source used to bamboozle the gullible. BTW from now wouldn't it just be simpler to post a link directly to what ever website is providing you with this stuff? I can then refute it without you having to try and be witty.
