Or suppose you're going the other way...you had strawberries and kiwi fruit in the second layer but you realize you wanted all the kiwi fruit to be up on layer seven. You're going to have to disturb the top three layers. In fact, you're going to have to do a massive deconstruction of all the top layers in order to do it. You'll have to pretty much start from scratch because the custard is certainly going to leave stains on the side of the bowl, the cake is going to leave crumbs, and if anybody really examines things, they're going to see that it's been disturbed. No, you're either going to have to live with the fact that the second layer is just strawberries or chuck the whole thing and start all over. That's how we know that the fossils we see in the strata lived at the time the strata was formed: The only way they could get into those layers is to be there at the time of the layer. Otherwise, all the layers above it would have to be wiped away in order to get those organisms into the layer and start over from scratch with the other layers. In order for organisms from, say, the Paleogene to show up in, say, the Permian, or the other way around, you're going to have to disturb all the layers in between in order to move them.Rrhain Thank you for your submission to Science.

quote: Completely backwards. Well, except for the statement that the alleles (why the sneer quotes?) are mutations. Because that's precisely right. Alleles are mutations of a gene. Since they are mostly neutral, they spread throughout the population in a process known as "drift." They don't become "junk DNA" because they actually code for protein and are expressed. That's why people with the allele for A blood don't die just as the people with the allele for B blood don't die. Interestingly, the O allele is a frameshift mutation of the ABO gene. Because the frameshift results in a different protein being made, the rest of the process that creates the antigens known as A and B doesn't follow through (kinda like how humans can't synthesize vitamin C even though most other mammals can...we have all the machinery to do it if only the GLO gene weren't broken in humans...but notice, this still isn't a deleterious mutation as humans take in sufficient vitamin C in our diet to prevent any negative effects.) And interestingly enough, it isn't "junk DNA" nor does it cause people to die. In fact, there are six alleles for this major blood group: A1, A2, B1, O1, O1v, and O2. Yep, there are three different alleles for type-O blood.Rrhain Thank you for your submission to Science.

Faith writes: Oh is that all this thing is about, those dips in the strata? The irregularities in the contacts between strata have a great deal of variety and are not just dips.
Way way back when we were discussing the Grand Canyon I drew a pictute to show how it SHOULD look if there had been any erosion on the surface and it looked like that diagram. As has been explained many times, erosion smooths out a landscape. It's like sandpaper for landscapes. Mountains and hills and rises are eroded, the products of erosion in the form of sediments are transported to lower areas, and over time the landscape becomes level. The exception is when water forms streams and rivers, which cuts channels into landscapes. Here's the diagram again:
So what caused the irregular contacts between strata if not erosion? I'd prefer an Edge or Moose answer, but I haven't seen yet where they've tackled this, so I'll take a stab at explaining the topology of the top few contacts. Remember the vertical is exaggerated. In case it helps anyone I found this paper full of information about the Geology of Michiganand the Great Lakes, though I only found it helpful on only a couple minor points during this exercise. From top to bottom:
I'll stop there. Moose/Edge: feedback much appreciated. Hope I wasn't too far off.
I drew another one with hills and valleys and a river too. Is that the point? Well, hooray, finally there's some erosion to report. Well, not really. While erosion is responsible for the unconformities (cessation of deposition is another possible cause of unconformities, but it's always seemed unlikely to me), the actual final surface that represents the contact between strata is usually going to be due to Walther's Law. Land surfaces are likely only preserved intact when rapidly inundated, which probably doesn't happen that often. Ours is an active but not frequently a catastrophic planet. In general sea levels slowly rise and fall, landforms slowly uplift and erode.
Take it back. There's salt in the layers, and that causes changes after the strata were laid down. Oh well. Again I'll need confirmation from real geologists, but I think the salt layers lying between limestone layers may represent warm shallow seas that receded/evaporated, and that the salt layers between shale layers may represent coastal areas that receded/evaporated. There is no deformation of the layers above the salt layers, so they caused no changes. Remember, the vertical scale is exaggerated. Salt deposits that rise through strata and can cause distortions and faulting typically involve massive amounts of salt, and these skinny salt layers don't appear to have migrated at all. Question for Edge/Moose: why the irregular left edge of the diagram? --Percy

That's how we know that the fossils we see in the strata lived at the time the strata was formed: The only way they could get into those layers is to be there at the time of the layer. But there's a big big problem here. Perhaps I needed to be more specific but the main problem is that you can't prove the time period itself, meaning prove that there ever was a time on the earth when certain plants and animals lived. You are assuming the time period, assuming that a particular layer of rock really does represent that time period, but that can't be proved any more than the animals in it can be proved to have lived at any given time. It's really the same problem. You can claim the rock is some particular age, but not that it represents a landscape with creatures in it.
In order for organisms from, say, the Paleogene to show up in, say, the Permian, or the other way around, you're going to have to disturb all the layers in between in order to move them. But that isn't the problem I had in mind. In my frame of reference the rocks are just rocks, not time periods such as Paleogene or Permian or whatnot. Edited by Faith, : No reason given.

Yes most are neutral, sorry, but others are deleterious and it is well kinown that beneficial mutations are very very rare. So the neutral mutations don't change the phenotype, but they do change the sequence of the gene which seems to me to be a destructive effect in itself. It's not needed, it's not useful.

Starting with the last question first ...
Question for Edge/Moose: why the irregular left edge of the diagram?
That's a schematic device to show the effects of weathering. More resistant units would extend farther to the left.
Again I'll need confirmation from real geologists, but I think the salt layers lying between limestone layers may represent warm shallow seas that receded/evaporated, and that the salt layers between shale layers may represent coastal areas that receded/evaporated.
Good observation. In this case it looks like there is not much 'salt tectonics' going on. There is no deformation of the layers above the salt layers, so they caused no changes. Remember, the vertical scale is exaggerated. Salt deposits that rise through strata and can cause distortions and faulting typically involve massive amounts of salt, and these skinny salt layers don't appear to have migrated at all. The interpretation of such evaporite layers is that they formed in a restricted basin in which evaporation was more than replenishment of water. There are several lines of evidence for this.
Well, not really. While erosion is responsible for the unconformities (cessation of deposition is another possible cause of unconformities, but it's always seemed unlikely to me), the actual final surface that represents the contact between strata is usually going to be due to Walther's Law. Land surfaces are likely only preserved intact when rapidly inundated, which probably doesn't happen that often. Ours is an active but not frequently a catastrophic planet. In general sea levels slowly rise and fall, landforms slowly uplift and erode.
When you have such variation, it usually means that the relief was low so you had minor transgressions and regressions. If you look up the term 'cyclothem' you'll get a boatload of information on that. However, in those cases, the rise and fall of sea level is not fast enough to plane off the mountains and sea cliffs. It's always a race (relative) between uplift and erosion. When the deposition is terrestrial (lakes and rivers and swamps, etc.), you can fill in some of the lowlands and stream channels that way. One thing to remember is that in such a stratigraphic column, whenever you see a wavy or jagged line, it indicates an unconformity. In this case there are a lot of unconformities at times when Faith says that there is no erosion occurring. Well, that might be true in the GC, but there was plenty going on elsewhere. We also see cases where some terrestrial deposits occur in channels which cut entirely through older formations. Another thing to remember is that the unconformity lines are actually isochronous, so even though they cut across the time scales they are the age of the younger formation.

I certainly have no problem with even extreme erosion of cliffs, but I can't regard some sand on top of tilted and apparently deeply buried siltstone layers as an angular unconformity, ...
I have always suspected that you have a hard time visualizing in three dimensions. Maybe you can visualize the paged of a book turned on end and then another book laid across those pages. If not, well, so be it. Everyone else can.
... just as there is no way that I can see how any current landscape could ever become a slab of rock such as we see in the geo/strat columns.
Other than the fact that we just explained it to you, sure.
I understand I'm probably not going to be able to persuade anyone of this, though I'll keep trying anyway.
Truth. And that is because your viewpoint contradicts reality. Edited by edge, : No reason given.

Yes, the amount of salt is something I already mentioned. Not even enough to cause the sagging.
Again I'll need confirmation from real geologists, but I think the salt layers lying between limestone layers may represent warm shallow seas that receded/evaporated, and that the salt layers between shale layers may represent coastal areas that receded/evaporated. You are always credulously treating the evogeo paradigm interpretation as unassailable fact and making my eyes roll out onto the floor. This is unprovable nonsense, and it ends any motivation I might have to answer you in spite of all the other reasons I have to ignore you.

Sand over the tilted siltstones would not form an angular unconformity, it would just bury the siltstones.
I guess you think you explained how that grooved landscape could become a slab of rock but it doesn't explain that at all, it's just eyeball-rolling mystification. You really don't seem to know that what you like to call "reality" is just an unprovable and really quite nonsensical impossible interpretation. Edited by Faith, : No reason given.

Sand over the tilted siltstones would not form an angular unconformity, it would just bury the siltstones. Younger sediments deposited on top of older tilted sediments is the definition of an angular unconformity. "Volcanics" can substitute for "sediments", younger and/or older. Still an angular unconformity. Moose Edited by Minnemooseus, : Change subtitle.

quote: All this is just assumption. I bet you haven’t even got any measurements of genetic diversity in dogs. (There’s plenty of phenotypic diversity but that’s due to aggressive selective breeding - funny how you keep missing that point.) And the fact that it is all assumption is the reason why you won’t persuade us. Even if your ideas about trilobites were plausible without assuming a massive program of selective breeding - which they aren’t. Try coming up with evidence if you want to persuade us. Real evidence, not lies, not things you’ve made up. Evidence that stands up to examination, without relying on cherry picking and or avoiding all the inconvenient details that go against your claims.

You are right I would point to the dog species Kind since they vary greatly in size and are all still dogs. The trilobites had a lot more genetic diversity to play with than today's dogs do, but dogs nevertheless have enormous genetic diversity compared to other species today, although they went through the bottleneck of the Flood and the trilobites are all pre-Flood with all or at least most of their original genetic diversity available. All this is just assumption. I bet you haven’t even got any measurements of genetic diversity in dogs. (There’s plenty of phenotypic diversity but that’s due to aggressive selective breeding - funny how you keep missing that point.) The great phenotypic diversity couldn't exist unless there was great genetic diversity in the overall dog population. There's less and less in each breed of course.

How can you have an angular unconformity unless the overlying sediment, whatever it is, forms a flat slab of rock across the tilted rocks? Are you saying it does, or that it's not necessary?

Perhaps I needed to be more specific but the main problem is that you can't prove the time period itself, Yes we can. We can do it very simply. We both know that the bottom layer had to be laid down before the top layer. So the deeper we go, the older the rocks get. Your difficulty is in explaining why certain fossil plants and animals are only EVER found in certain layers of rock. And always the same layers for the same fossils. Floods do not and can not sort fossils in order. For that you need a miracle. Strawberries are only ever found in red jelly. Kiwi fruit in green jelly and green jelly is ALWAYS found above red jelly. To be that way your mother put the red jelly in first with the straberries and the green jelly in second with the kiwis - after the red jelly had set. If she'd put it all in together and shaken it all up she'd have yellow jelly with kiwis and strawberries throughout.
meaning prove that there ever was a time on the earth when certain plants and animals lived. And that's your proof that 'certain plants and animals' lived at at certain times - if only relatively. Then just to put the cap on it, radiodating directly proves that red jelly is older than green jelly. And by how much. So there it is, as simple as it can be made to be. All you have to do to prove all thi wrong is find a kiwi fruit in with the strawberries. Your inability to do this should tell you something.Je suis Charlie. Je suis Ahmed. Je suis Juif.
