From Susumo Ohno, The notion of the Cambrian pananimalia genome, Proceedings of the National Academy of Sciences USA: Vol 93, No 16, 8475-78, August 6, 1996.
Assuming a spontaneous mutation rate to be a generous 10 -9 per base pair per year and also assuming no negative interference by natural selection, it still takes 10 million years to undergo 1% change in DNA base sequences. It follows that 6-10 million years in the evolutionary time scale is but a blink of an eye. The Cambrian explosion denoting the almost simultaneous emergence of nearly all the extant phyla of the Kingdom Animalia within the time span of 6-10 million years can’t possibly be explained by mutational divergence of individual gene functions.

Uh, Mams, I don’t think Randy was implying I was taking the quote out-of-context. Explain why you think Ohno’s speculation about differential usage of genes somehow rescues his prior observation from being support for TB’s argument. I did not need Ohno’s speculative conclusion because even it subtly supports TB’s argument.
FYI, I have the paper and was well aware of Ohno’s conclusions based on this unfavorable data for evolution. I cited this paper in my fossil article almost a year ago:

I wrote:
Some evolutionists who realize the soft-bodied excuse no longer carries weight are invoking strange ideas in an attempt to deal with this mammoth problem of the sudden arrival of such complex and diverse life. One evolutionist has proposed that all the animal phyla before the Cambrian explosion had nearly identical genes, and that differential usage of the same set of genes accounted for the extreme diversities of body plans.19 There are two primary problems with this: 1) he offers little evidence to support his hypothesis; 2) even if true it would only serve to push the problem back in time - it would then fail to explain why the fossil record left absolutely no trace whatsoever of such a massive accumulation of all this shared genetic information.

Fred, Do you accept Ohno's claim that it takes about 10,000 million years to get a 1% change in a genome?
No, I actually believe it’s worse than he states! (he’s assuming none of the mutations are removed via selection)
quote:
If so how much change can one expect in 5,000 Years?
Plenty!
Maybe this is before your time, but do you remember that annoying commercial of a German scientist who said it’s better to push a car than to pull it ? Well, imagine him today commenting on this discussion, saying it’s easier to shuffle a deck than to create it!.
Bottlenecks, subsequent drift, radiation events, all could account for considerable diversity among genomes within 5K years. Even non-random mutations could play a role!
What do the evolutionists have? Nothing, really. Why can’t you propose the same mechanisms to account for the Cambrian explosion? You even get millions of years as opposed to thousands. That’s a lot of points to spot you.
The reason is due to you starting point - conventional wisdom is that your precursors do not already have the genetic information and need to somehow produce it in a very short period of time. Our starting point is 30K or so kinds, each with an information-rich genome. That is, we can start shuffling the deck right away. You need to first create the deck, then you can start shuffling!
This is why Ohno was forced into his differential gene story. He essentially created the deck from scratch. All he really accomplished was to push the problem back in time, kind of like what the panspermia crowd has done!

Uh, Doc, please either return your hasbro PhD, or check carefully what I wrote.
Do you realize the vast number of dog breeds are essentially artificial bottlenecks? You find a trait you like, then you bottleneck a pair, and before long you have another dog breed.
But I see what you have done, and what your argument amounts to is a strawman. Your mind is locked into intra-species, I am thinking inter-species. I agree that bottlenecks reduce the genetic diversity of the new, bottlenecked species (INTRA). For example, I suspect poodles have much less genetic diversity than wolves. Bye bye strawman.
But after various bottlenecks, the diversity of the original parent population, at least from a global perspective, has been realized (INTER). In other words, if I saw a picture of the original two domestic dogs, then a picture showing many different dog breeds, I would conclude that the 2nd picture is a reflection of the genetic diversity of the dog. This diversity was the result of various bottlenecks and subsequent mutations.

Bottlenecks, now there’s an interesting point. Don’t bottlenecks show up in the genome of species that went through a bottleneck? Why don’t all species show evidence of a bottleneck about 5,000 years ago? You are claiming that the bottleneck was down to 2 of each kind (whatever that is). Why is there no genetic evidence of all these bottlenecks? Why don’t humans have more genetic diversity than most animals? Weren’t there supposed to be 8 humans and only two of each unclean kind on the ark? Humans should have more diversity in our species than the entire genus (or maybe family or at least Kind) of unclean Kinds. Does genetic analysis show this? I don’t think so. Why not?
Randy

As Peter stated this truly is an irrelevant question. I believe even from the evolutionary POV, there is nowhere near enough data to even make speculations, let alone draw any conclusions as to when various species bottlenecks occurred. There is much in the genetic code that is still a big mystery. For example, there are these jumping genes (retrotransposons) that can cause dramatic rearrangement of the genome, and we seem to be light-years away from reverse-engineering these (which BTW give all the appearance of non-random, pre-programmed "mutations").

M: Wrong, each bottlenecked group loses some portion of the greater original diversity...it is not sitting there static in wolves who are under selective pressures of their own. If everyone in Africa died tomorrow except for two people, the African population would have suffered a tremendous bottleneck and at the same time, the human gene pool would have lost a tremendous amount of genetic diversity...humanity would not have realized some genetic potential of the original (pre disaster) population as you are claiming.
I suspect most understand the point I am making, and I suspect you are one of them but are obfuscating with the aid of strawman arguments. It was asked how the diversity of life can be explained given a starting point of 5K years ago with some number of kinds of animals. I illustrated how bottlenecks and subsequent drift would easily account for some if not much of the diversity we see, and I provided dogs as an illustration. I did not say the genome or the gene pool became more diverse. Its diversity was realized . A deck of cards contains some diverse number of different cards (13 in the case of a poker deck). By itself its diversity is not apparent or interesting. When you fan the cards out its diversity is realized, becoming both apparent and interesting. Bottlenecks in a sense help fan the cards because various traits can be amplified. Radiating a population would also fan the cards (or melt them ). Directed mutations (pre-programmed variation) would also fan the cards. Is this really that hard to understand?

You have utterly failed to explain how the homogenizing action of inbreeding depression ("bottleneck") actually creates diversity
I never said this creates diversity. In fact, if you recall I corrected Mamuthusus when he denied genetic information was lost due to bottlenecks (he later recanted, claiming I misunderstood him). What I said is bottlenecks & drift is a process that helps realize the already inherent diversity. If you don’t understand the difference between create and realize there is no point debating this further. I can only say that blue = blue for so long.
quote:
Your dog example is spurious - they remain the same kind, after all, and their diversity is nowhere near fully "realized" (if I understand whatever the hell that means)
It is obvious you do not know what realize means, and it has led you to erect a strawman. You guys are on a role on this board with these assemblages of straw. I also did not say dog diversity was fully realized via breeding (which I pointed out emulates bottlenecks). In fact I completely agree with your sentence above (beginning at they remain, of course).
quote:
why haven't new species of cheetahs and elephant seals been produced before our very eyes? After all, you're the one who's claiming that bottlenecks produced lots of new species from the Flood. This IS your mechanism, right?
It is one mechanism that has surely produced new species, we have observed it. I remind you that species is a man-made, subjective term. I have debated some biologists who say that merely isolating a population can qualify the isolated group as a new species. Consider that there are at least 32 species of bats. Each species could easily be the result of population isolation (pseudo-bottleneck) from a parent population (bat kind).
quote:
(per your request to address this from the Intelligent Design Debate Continues thread)
Q: there are approximately 1.4 million identified living speciesBased on biodiversity studies, there may in reality be as few as 10 millionPlease provide evidence, of any kind, or even a decent explanation, of how the observed mechanism of random mutation etc caused 18,000 kinds to became 10 million in 4500 years
You are making false assumptions. We first must consider only the kinds that were required to be on the ark. We are not required to account for all the species of algae, fungi, insects, fish, mollusks, etc. (note that there are almost a million catalogued species of insects/spiders!). To compare apples to apples, I will compare the number of estimated kinds (which is based on known species) to the number of catalogued species required to originate on the ark. My source for species is:
Page Not Found | World Resources Institute
4,000 Mammals
4,184 Amphibians
6,300 Reptiles
9,040 Birds
The total number of species that would have had to originate on the ark is 23,524. As you can see, it is entirely reasonable to achieve 23K species from an original 18K kinds over the period of 4000 years! It only requires 1.3 species per each kind. As I mentioned earlier, there are over 32 bat species, at least a dozen rabbit species, etc. It appears the 18,000 "kind" estimate is likely too high.
Problem solved.

Don’t worry Mams I stopped taking you seriously after your debacle with your random mutation strawman (even the posts’ originator realized his error; only you remain a lone hold-out to your incredible illogic).
quote:
M: You are making subjective and qualitative statements on what is interesting with regards to diversity...inbreeding does not release "captive" variation. A severe bottleneck would leave you with a four of hearts and no deck of cards...hardly "realized" diversity.
As I have always stated, the resulting bottlenecked population has indeed likely lost genetic information from the parent population. It took several posts before you would come right out and agree with this after you had originally claimed cheetahs had not suffered genetic loss (BTW, in case you missed it, I also provided per your request a reference from a researcher who agrees that cheetahs likely have lost genetic segments). What you refuse to understand is this vein of the argument is that the entire deck of cards still exists as long as the parent population still exists. Bottlenecking a portion of that population, and subjecting it to subsequent selection may cause some diversity to be realized, not created.
quote:
By the way, none of this helps explain why there is no evidence of bottlenecks in ALL species that would have to have occurred if the ark myth were true...yet another bible killer that you ignored.
Wow, big Bible-killer. See my post to Quetzal. To summarize, there are 23K species that would have been required to originate on the ark. Creationist estimates the total number of kinds to be around 16-18K (I apologize for my previous 30K number, I’m not sure where I saw that). That means roughly 1.3 species per kind is all that is needed in 4K years.
BTW, some day when you get a job perhaps you might realize the difference between "ignore" and "lack of time". One of the refreshing things about this board is that I've found that most of the evolutionist requlars here realize the difference. Why do you have trouble with this? Taking in too much of Page's canned rhetoric? Perhaps you too have less faith in your arguments, and thus turn to such empty complaints? Just checking.

Actually there are far more than 32 bat species. There are 18 families of bats and I think around 900 known species. There are 355 known species in the 42 genera of Vespertilionid Bats which represent just one family.
Thanks.
quote:
One problem with your numbers that you seem to be ignoring is that you need representatives of all the extinct "kinds" of land animals that ever lived on earth to be represented on the ark. I think this changes your numbers quite a bit and every time new extinct kinds are discovered it makes your problem worse.
My copy of Woodmorappe's book is at home, but I just found on the web that you are correct that his kind estimate is 8K, not 16K. Woodmorappe's number apparently also accounts for extinct kinds. Regardless, that means each original kind needs to account for only 3 species each. Let’s say I’m off substantially, by an order of 10. That means each kind still only needs to account for roughly 30 species (sub-kinds) each in 4K years. You have shown that bats alone account for 355 known species. I know there are also many species of mice. I think it should be quite evident to everyone that an average of between 3 and 30 species per original "kind" is quite feasible, and thus Quetzal’s argument is toothless.
quote:
Of course the idea that a 600 year old man and 7 family members cared for 16,000 of 8,000 different kinds of animals for a year on a big wooden boat during a global flood is totally absurd but that's another subject.
IMO Woodmorappe makes a solid case in his book why this is not absurd (even without invoking miracles). I agree that's another subject.

No. I can’t keep repeating myself. Please go back and read what I wrote.

That seems to be a brand new claim.
It seems this way to you because you were unable to follow the discussion.

Previously, you stated that this loss occurred in the existing cheetah population.
Huh? I stated that the cheetah has less genetic information than its pre-bottleneck parent species. Why is this so hard to understand? This is a simple, straightforward statement.

A great example of what? Loss of genetic diversity in an existing species? I agree. Creation of a new species due to loss of genetic diversity? This seems to be your claim, bit I have yet to see anything resembling evidence. Could we expect that this is forthcoming?
The cheetah is a cat kind. A branch of this cat kind became isolated. This resulted in the CHEETAH. The cheetah has LESS information than its parent, pre-bottleneck cat kind. I already provided a citation from a CHEETAH expert who agrees it is likely the cheetah has lost gene segments.
Lions and Tigers also share a common cat kind ancestor. Each likely has less information than their common ancestor cat kind. Savvy?
quote:
Rapid speciation of many species from a single kind will by necessity require creation of a large number of new alleles. Since you previously said that loss of alleles in the cheetah population is a loss of information, gain of alleles from the original kinds to many new species is a gain. Or do you wish to treat us to more double standards?
No, what I wish is that you would follow the discussion. I do not know of a single evolutionist trained in info science who thinks the appearance of a new allele necessarily represents new information. Yet this is what you keep claiming, because you cannot get it through your thick skull. Find me ONE evolutionist who has a background in info science who thinks a new allele always equals new information. If this is true, then DISEASE = new information by this standard. Utter nonsense.
quote:
I know BS when I see it, and I see it. These kinds of arguments may work on the faithful, but most people can see right through your double speak.
The problem is, your blinders are on so tight you deny that 1+1=2. Let me lay it on the line: You have to be a complete moron to believe deterioration = new information. You would give flat-earthers a good name.

Not being a bat expert, I qualified my number with at least and over because it was based on what little I scrounged up on the internet.

What you refuse to acknowledge is the huge disparity between 23K and 5-50M. Quetzal’s argument was based on a flawed assumption that was several orders of magnitude off, yet you remain true to form and still defend it. You go guy! Loyalty to the cause at all costs!

I believe Mams has blown a gasket. I'd recommend pursuing immediate medical attention!
Regarding founder vs bottleneck, I know the difference. In a sense a small founder population is really no different than a bottleneck. DO you deny this? If so, please educate me, oh wise one.

I never said this creates diversity. In fact, if you recall I corrected Mamuthusus when he denied genetic information was lost due to bottlenecks (he later recanted, claiming I misunderstood him). What I said is bottlenecks & drift is a process that helps realize the already inherent diversity. If you don’t understand the difference between create and realize there is no point debating this further. I can only say that blue = blue for so long.
Never said it, hunh? How about this bit here, then?
quote:
It was asked how the diversity of life can be explained given a starting point of 5K years ago with some number of kinds of animals. I illustrated how bottlenecks and subsequent drift would easily account for some if not much of the diversity we see, and I provided dogs as an illustration.
Sure looks like you're claiming bottlenecks cause/create/whatever diversity. Those are your words, right? If you didn't mean them, you should have been more clear.
Hence why I followed-up with the top paragraph. I thought it was clear as a whistle. Even the emphasized sentence you quoted should have been clear. It is simply true that bottlenecks and subsequent drift help us SEE the diversity. It does not create the diversity, it helps us SEE it. Realize, see, all words with solid definitions. I am not the one having grammar problems here. You too appear to be equivocating/hairsplitting. But I’m used to it. I really in a sense don’t blame you. If the point you are defending is specious, well

Besides the obvious error on the number of bat species (like by an order of magnitude),
Oh please. Like I said, hairsplit... but I didn't expect this specific hairsplit from you. See my comments to Page, who appears to be a bad influence on some of you. Do you want provocative, reasonable debate, or silly nonsense?
quote:
The total number of species that would have had to originate on the ark is 23,524. As you can see, it is entirely reasonable to achieve 23K species from an original 18K kinds over the period of 4000 years! It only requires 1.3 species per each kind. As I mentioned earlier, there are over 32 bat species, at least a dozen rabbit species, etc. It appears the 18,000 "kind" estimate is likely too high.
This is almost too silly for words. Okay, tell me again your rationale for excluding insects, plants, fresh-water fish, etc from your "kinds"?
This is your way of avoiding the fact you were orders of magnitude off? The Bible did not require insects, plants, fresh-water fish, etc. Your argument was based on what the Bible required on the ark. How these non-ark organisms survived outside the ark is another debate. Such is a fair question, and a good discussion, that has been discussed many times. The point is, it’s another topic. Your original claim requiring the ark to somehow accommodate the originators of 10 million species was a fallacious argument that needs to be put to rest.
