Dinosaur Evolution Comes Into Focus
nickynicky9doors writes: "National Geographic has an article celebrating the work of dinosaur hunter Paul Sereno and his colleagues. New Thinking On Dino Evolution provides an overview of the recent discoveries and the conclusions and questions that follow the discoveries. One of the lines of inquiry asks how the breakup of the SuperContenient Pangaea impacted the evolution of the dinosaurs."
Please take note of the article on OpenBSD and StarOffice as well...
"For one thing, that the breakup of the ancient supercontinent Pangaea was not rapid, as widely believed, but slow enough to drastically limit dinosaur evolution in the region. "
I beleive that geographic isolation (punctuated equilibrium) differentiated species after a long (the longer the better) period of mutation. Are there any biology/ecology people out there who can correct me?
The article repeatedly discusses the amazing radiation, yet they wonder how it occurred as they ask about how the supercontinent broke up?
"In a 1999 report in the journal Science, Sereno said: 'I think there was some kind of a tenuous land bridge [linking Europe and Africa] for several million years' after initial breakup of Pangaea. 'That land mass prevented the evolution, in isolation, of a unique southern dinosaur fauna.'"
Is it absolutely crazt to think that with the same pressures, and starting from the same genetic base, the two continents would develop similar dinosaurs?
Does the article explain this that badly (I assume) or are these scientists just dumb?

I think I'll respond by recounting a conversation I had with a Sunday School teacher back when I was a kid. Paraphrased, as sadly I had not the foresight to record it:
.....God works in mysterious ways.
Teacher: The Earth was created in 6 days, 6000 years ago. There were no such things as dinosaurs.
Me: Then where do all these bones come from?
Teacher: God put them there.
Me: Why? To tempt people into not believing in the bible? Isn't that Satan's job?
Teacher: Ummm....
Me: Cause if God is all loving, and wants us all in heaven, why would he tempt people into not believing in his word? And if he's all knowing, doesn't he already know who would believe in dinosaurs and who wouldn't?
Teacher:
Some Other Kid: Maybe the 6 days are really like 6 billion years, and all the dinosaurs and stuff happened during like the 3rd and 4th day, which was really billions of years?
Teacher: No, that's not how it is at all. Let's move onto something else...
(Still waiting for Jerry Fallwell or Pat Robertson to blame dinosaurs on gays and minorities...)
It hurts when I pee.
Just because your Sunday school teacher was a bumbling parrot, it doesn't mean that you're right or that he's wrong.
The fact is that although many things appear to be very old, there is deducible evidence to prove that the Earth is only 6,000 years old.
OK, so "many things" on Earth appear to be very old, but the Earth itself is only 6000 years old? Dinosaur bones from space? Someone added a few too many zero's to estimated ages of deep ice core samples from the Arctic? Carbon dating a liberal myth? Help me out here.

the SuperContenient Pangaea
this sounds too much like an anime title.
I wonder if you can tell me when god made the angels, and why he made them so powerful that one can at least rival him? And if all humans are decendants of Adam and Eve, why are they so different - no wait, I also forgot that we all have Noah in our lineage. Talking about Noah, how did he fill all kinds of animal existing (and those who once existed but have since been exterminated by man) into that little ark? And why is there no mention of say kangooroos in Noahs tale or the dozens of distinct finches Darwin described?

1) when god made the angels
Duh. In the beginning. I'd estimate that to be somewhere around 6,000 years ago.
2) why he made them so powerful that one can at least rival him?
Hardly a rival. The book of Revelations says that Satan will be cast into the pit of Despair with other non-believers.
if all humans are decendants of Adam and Eve, why are they so different - no wait, I also forgot that we all have Noah in our lineage.
Genetic drift explains the races. The tower of Babel explains the cultures.
Talking about Noah, how did he fill all kinds of animal existing (and those who once existed but have since been exterminated by man) into that little ark?
The ark was huge. The specs are in Genesis. He only took baby animals (they're much cuter and tamer and smaller than the adults).
why is there no mention of say kangooroos in Noahs tale or the dozens of distinct finches Darwin described?
There's no mention of many different animals in the story of Noah's ark. Does this mean that they don't exist? Finches and other birds can fly and did not need to be kept explicitely on the ark. They would have found their way to it regardless (it was the only dry land available for landing)
"He only took baby animals (they're much cuter and tamer and smaller than the adults)."
Baby cockroaches, ringworms and fruit flies? How the heck do you find and catch baby fruit flies? What did he keep them in? Did he have an inventory? How did he know he got everything? Hey, why did water dwelling creatures get a pass? I mean a flood doesn't affect them much. Why didn't the massive tidal forces cause Mount Ararat to be submerged?
So many questions.... I hope you can help.
Baby cockroaches
You can chalk that one up to bad hygiene. Roaches were probably everywhere, creeping everyone out, I'm sure.
ringworms and fruit flies
Twofer. You get a couple pigs, and you'll get yourself a whole swarm of pests. Besides, God protected all the animals that were worth saving (as much as we'd argue the 'worth' of an animal) by guiding Noah's hand in selecting the animals.
What did he keep them in?
Jars. *rimshot*
No, of course the pests were kept in the ark.
Did he have an inventory?
Large inventory. Did he keep it written down? Probably not, but what's the point when anything you didn't bring aboard would be killed anyway?
Hey, why did water dwelling creatures get a pass?
Because they could swim? What's the question?
Why didn't the massive tidal forces cause Mount Ararat to be submerged?
The waters were subsiding when the ark landed on Mt Ararat.
Cool. How long did this take him? How big was the boat? What about the insects who have life spans measured in days? Or the one's who only come out every few years? How many species were aboard? All of them? How did the tree that the branch was brought back from survive being violently submerged?
Why didn't the lions and tigers eat Noah? Or at least eat all the smaller animals? Hehe...they must have been full on the griffins and unicorns ;)

2) And still he almost completely rules the world. Or so the preachers say.
3) The Tower of Babel barely explains the different languages (and their similarities and differences), but it does not explain different cultures. Oh and about that genetic drift - you mean mankind changed? As in evolved?
4) The Ark was tiny compared to modern ships.
That would be (ca.) 450 feet (150 m) long, 75' (25 m) wide, and 45' (15 m) high.5)Genesis 7;14 They [Noah's family], and every beast after his kind, and all the cattle after their kind, and every creeping thing that creepeth upon the earth after his kind, and every fowl after his kind, every bird of every sort.
Sorry dude, the book says he had all the birds on board. (Isn't the internet wonderful? God must have created it.) Let's ignore that the Bible doesn't mention all the different animals that exist - how did they get where they are now? Did Noah drop them off? Why doesn't that get mentioned either?

I'll bite. What if the earth was formed from already existing materials? In other words, the dinosaurs lived on a planet that was destroyed and the stuff from that planet was "re-organized" into the earth. I'm not saying that this is the case, but it would satisfy the existense of bones, radio carbon dating and most other time related issues with creationism.
ASCII tastes bad dude.
Binary it is then.
But that of course suggests that God had previously created one or more other planets that were capable of sustaining life, which is totally against creationism.

How about Satan/Lucifer? Revelation talks about a war in heaven... Just because God won does not mean it was a landslide.

Let's see there is the curse of Cain (a skin of blackness) and the tower of babel to give us different languages and of course thousands of years in various parts of the earth to give us culture. Sounds pretty easy to me.
how did he fill all kinds of animal existing (and those who once existed but have since been exterminated by man) into that little ark? And why is there no mention of say kangooroos in Noahs tale or the dozens of distinct finches Darwin described?
Good questions! The Ark was big by defenition so I don't think it is too far fetched to believe that he fit all the animals on the ark. Keep in mind he only needed to worry about air breathing animals (insects, mammals, reptiles, etc.) It probably took a long time, but I recall something in Genesis that mentioned God's help in getting all the little crawlies to cooperate. As for Darwin's finches, who is to say that they didn't get on the ark with Noah? There is no proof either way and you are left with faith (for or against) which is the basis for any religion anyway.
ASCII tastes bad dude.

which is totally against creationism.
Maybe the maistream creationists would balk at this notion, but certainly not me! It would be terribly egotistical to say that we are the only sentient beings God has created (assuming you believe in a creation). If God has all power, then He certainly can create more than one life supporting earth! May I ask why you think this is the case?
ASCII tastes bad dude.
Binary it is then.
Gee, I don't know... why don't the lions and tigers at the circus eat the monkeys?
Well, that's pretty much what I believe as well, along with some other concepts (6 days=~6 billion years, evolution is a natural process God created). I've found, however, that arguing points like this tends to get you labled as "non-creationist", at least by those who steadfastly hold to the literal definition of creation as it's described in the Bible.
It hurts when I pee.
How long did this take him?
Until the rains got really bad. Probably a while.
How big was the boat?
Specs are in Genesis. You can look them up. Measurements are in cubits, so please account for the conversion factor.
What about the insects who have life spans measured in days?
Their reproductive cycle must also be on the order of days, so there's no problem.
Or the one's who only come out every few years?
Considering that they exist today, it isn't hard to extrapolate that Noah was able to fit them onboard.
How many species were aboard? All of them?
Well, all the ones we have today.
How did the tree that the branch was brought back from survive being violently submerged?
Trees are tough and the branch was probably broken off already anyway. I don't think a dove can tear an olive tree branch off so easily.
-- 3) The Tower of Babel barely explains the different languages (and their similarities and differences), but it does not explain different cultures. Oh and about that genetic drift - you mean mankind changed? As in evolved?
Of course mankind has changed. I'm not a carbon copy of my parents. Nobody argues that species don't change and evolve. The argument is whether or not they change into other species. The argument is over whether or not an aligator, a canary, AIDS and people all have a common ancestor.
Secondly, about different cultures... what needs to be explained? It is common sense and observable fact that cultures change. It doesn't need an explaination in the Bible, and it doesn't have anything to do with the evolution (or not) of species.
-- 4) The Ark was tiny compared to modern ships.
Modern cruise ships and supertankers are in the neighborhood of 1000 feet (~300 m) long. Modern aircraft carriers are on the order of 600 feet long. So 450 feet long is smaller than the world's largest modern ships, but hardly tiny.
"every bird of every sort" is referring to the fact that every type of bird was represented, not that every bird on the face of the earth was in the boat. Read verse 3 and you'll see that. Why ignore the fact that the Bible doesn't mention all the different animals that exist? It never attempts to list them all, what's the point? Noah was instructed to take seven pairs of each type of clean animals, 2 pairs of each type of unclean animals, and 7 pairs of each type of bird. And why do you question how animals got to where they are now? Don't you think they walked, swam or flew?
So the Kangooroos walked from Mt. Arrarat to Australia.

To the guy who modded me down from perfect to terrible Karma - Apple haters still suck
All your questions are answered in Genesis. Noah spent 120 years building the Ark. The dimensions have been previously posted here. The olive branch was newly grown. Seeds would have survived the flood. 40 days after the ark came to rest on the mountain, Noah sent out a dove, but it came back with nothing. He waited another week and sent it out again, and this time it came back with the olive leaf. So the olive leaf had had 47 days to grow.
I've found, however, that arguing points like this tends to get you labled as "non-creationist", at least by those who steadfastly hold to the literal definition of creation as it's described in the Bible.
It's narrowmindedness like this that makes the world a dark and dreary place. However it is god to know that there are those who still search for answers without blindly accepting the majority view.

I'm not sure why you ask that last question. Mount Ararat WAS submerged. It was 150 days after the rain stopped that the ark came to rest on the mountain. Even then the mountain would have still been underwater.
Stupid. They hopped.
...lunchtime doubly so.
Ever think that you simply don't understand how time works? Einstein proved it's relative; I feel certain it's not even linear. I think you'd make a lot more sense claiming the earth was created yesterday and everything in the past is just memories. When you say the earth was created 6,000 years ago, you're playing by science's rules, which prove the earth to be a lot older than that (but of course can't prove it wasn't created. In fact, I think the Big Bang theory is the most creationist postulaion ever to come from science, because you have to ask: who lit the fuse?).

actually the largest supertankers are on the order of up to 1500 feet long and can weigh up to 400,000 tons and aircraft carriers are 1000-1102 feet long, and slightly under 100,000 tons of displacement. and both are nearly 200 feet wide (the width is dictated by the width of the locks in panama). so the largest ships today are substantially larger than predicted size of noak's ark.
2) What about plants? They don't like being submerged several thousand feet below water, even if it isn't salt water. Which brings us to fish - there are salt water fish and sweet water fish.

To quote Gen 6:19-20 "19 And of every living thing of all flesh, two of every sort shalt thou bring into the ark, to keep them alive with thee; they shall be male and female.
20 Of fowls after their kind, and of cattle after their kind, of every creeping thing of the earth after his kind, two of every sort shall come unto thee, to keep them alive."
So 'every living thing' would encompass just about every animal/plant/fish etc...
Which of Noah's daughters-in-law was black?
Gen 10:6-20 details the lineage of Ham. We see that his descendants populated what is now Egypt, the Middle East and Africa. While there is no biblical account of Ham or any of his descendants receiving a curse like Cain, it seems likely that they indeed did.
What about Asians?
Again, there is no biblical account of every race or creed of mankind. Suffice it to say that skin color, eye shape and any other physical attribute of men can be said to be influenced by environment. The science behind that is pretty evidencial (especially for skin color.) However, we don't know for sure since there were no records kept and there is not a person alive today that can act a witness to the changes. Who knows, but the childred and grand children of Noah had all the genetic diversity to support the entire spectra of human races.

Here's betting that you don't know what the word "theory" means to a scientist.

No, I had a beer with him last week, and he told me that the geology was correct and it was the Bible that was faked. He had originally toyed with the idea of faking the geology just to have a joke at scientists' expense, but decided faking the book would make for a much better prank.

Well, science is based on "evidencial" evidence, so I'm not sure what you are saying here. However, in response to your comment about no records being kept, I point you towards your friendly neighborhood anthropologist or archaeologist; either will be able to give you some rather good unwritten records of the progress of human culture, and how almost all of it predates anything in the Bible.

I have spoken with a few anthropologists on this subject two years ago. One fellow from the University of Arizona was very complementary of the bible and its record of human history. As for predating things in the bible, where do you get this idea?
