Dinosaurs?

oops...duplicate

I probably missed it but the 'tail' referred to in regards to the Behometh is a euphemism for penis.

 

[Pete Harcoff]

Hey, they didn't censor the dreaded p-word. When'd that happen?

 

[David Gould]

That is odd. I was thinking of writing it 'pen is' but for some reason tried it without doing that. Maybe the science section is allowed to use the word: we are sooo mature, after all.

jdunlap: Still curious about the answer to my two questions I asked you way back yesterday, they preceed a response to one of your posts, so it would be nice for an answer.

i dont think dinosaurs ever existed

 

[David Gould]

i dont think dinosaurs ever existed

Why is that?

 

[Jet Black]

so liek, what are all the fossils and stuff then?

Clue me in as to which ones, and I'll answer them tomorrow hopefully. (Sorry , but I don't see any I've missed. But then I'm awfully tired , so I likely missed them somehow.)

What is the decay rate of heme?
Can you show me where they found DNA and Amino acids?
Why cant the fossils be un Permineralization in the center and still be old?

The decay rate of heme, even if it were to be extrordinarily long, would definitely not be 65 million years old.

Besides the heme, there were also amino acids and DNA found. The decay rates of DNA show that it should not last more than 10,000 years, and yet it is mostly intact. Amino acids also are fairly volatile and have a fairly fast decay rate. Osteocalcin was also found, and it is much more volatile than heme. Also, the mere fact that they are unfossilized means that they can't be very old. Finally, there is evidence that antibodies in the rats reacted specifically to hemoglobin, not just heme.



There are 5 main types of true fossilization:

* Permineralization fossils are when minerals seep in and displace the original material. Only a small portion of these bones are permineralized.
* Trace/impression fossils are when an imprint turns to stone.
* Casts and molds are caused when sedimentation leaks into the impression left by a decayed object.
* Carbonization fossils are a black film formed when the volatile organic compounds disperse from a decomposing organism, leaving a thin residue of carbon.
* Recrystallization fossils are formed when unstable minerals return to their original state. This is mostly limited to mineral-based shells.
These bones do not fit these types of fossilization. What type of fossilization preserves the original material? None that I know of. The very definition of fossilization indicates that the original matter was displaced.

Clue me in as to which ones, and I'll answer them tomorrow hopefully. (Sorry , but I don't see any I've missed. But then I'm awfully tired , so I likely missed them somehow.)

Creationists have returned - apologies for declaring your departure prematurely thus I return to as this is much fun

You could also say that Noah might have had a couple aliens on the Ark as well, since there is no evidence to the contrary.

Your point being? In fact by your own arguments, Noah only took 2 of each kind of animal onto the Ark, therefore no aliens were on board anyway I think extra-terrestrial life is probably a topic for another thread isn't it?

What is the decay rate of heme?

I may be wrong, but I was under the impression that heme is a protein complex bound together by an iron ion (!) or something like that, and would therefore only decay above temperatures of 40 degrees Celsius (denaturing of proteins). Equally the proteins can only be broken down by biological action if decay agents (bacteria etc.) can actually get to the heme in the first place - ergo if the bones were found under ice or in a similarly cold place that was inaccessible to decay agents there is no reason why the heme should decay at all. However I could be wrong as I just kinda thought my way through this and didn't look it up or anything [waits to be proved a fool].

well, if they censored it every time it would be annoying to discuss reproduction and the like in a science forum...

Nobody's made any fun of her disabilities. People have criticised her writing, which is on a lower level than that of my 9 year old niece. This has nothing whatever to do with her disability. Being deaf does not give you a licence to write like a child or prevent you from writing like an adult.

so people that use English as a second language should be able to write it perfectly? God, People that use English as a FIRST language can’t write properly.
souldn't you all respect people?
I met christy on a ROMANCE forum. and we RESPECT her no one makes fun of her on there that knows her.

 

[wolflady]

Thank you, Redruby! Be careful!

I realize that probably only few knew that ASL is her first language and English is her second language, but that does not give a licence to hurl insults at her. I have not heard any of those who were guilty of this, now that you know the full story, offer wolflady a public apology for such shameful behavior towards her.

You now have that oportunuty. Let's see what you're really made of. Will you offer her a public apology here, or will you continue to try to justify your disgraceful behavior?

Nobody here has hurled any insults at her. Two people (of whom I was one) have criticised her writing skills as being child-like. They are. Somebody else posted that she was deaf, apparently by way of explanation. Nobody at any stage suggested that English was not her first language; had they done so, no doubt people would have been more reluctant to criticise her writing skills. Certainly, nobody has acted "shamefully" towards her.

On a more general note, anybody attempting to contribute to a forum like this has a responsibility to ensure that their posts are reasonably easy to read (grammar, spelling, etc.) This being the net, of course all of us post bad grammar and spelling at times - nobody is expected to be perfect. However, whether English is your first language or your thirty-first, the onus is on you to be able to communicate coherently, or not contribute at all. If your written communication skills are so poor that others call them child-like, expect to be criticised for them.

And there you have it, folks.

 

[toff]

Yup. There you have it. The reason someone with poor written English skills was told she had poor written English skills. On the other hand, if you can evidence any "insults", "shameful behaviour", or "disgraceful behaviour" from anyone to her, then you may have a point. Until then...stop whining.

Like you, right?

I still don't understand this. are you implying that deaf people cannot write properly?
