Author | Topic: When science use biblic words (Re: Lazarus Taxa / Ghost Lineage) | ||||||||||||||||||||
Denesha Inactive Member |
Dear all,
Feel free to give your opignion about this term:
LAZARUS TAXA Do you think this is a step toward a reconciliation? See more about here: http://palaeo.gly.bris.ac.uk/publs/Benton/1999Wignall.pdf PS. This is my first hundred post and I would like to thanks you all. I can't easily detect classic jokes in replies. But reading and posting here were very instructive. Denesha

When I clicked on the link it wouldn't go through.
Could you please explain what Lazarus Taxa is? It sounds like a Dinosaur.

Dear Born2preach,
It takes arround 20 seconds to download this PDF file with a low speed modem. But you need Acrobat to read it. I didn't mention that. So, it's my goodness day, here is the intro:
Better now? Denesha

Neat is all I can really say about it. I don't think there's anything wrong with calling it 'Lazarus' at all; but a fossil is still dead. Since it just wasn't visible for awhile I would've called it the 'phantom'. But that's just me.
Wanna feel God? Step onto the wrestling mat and you'd be crazy to deny the uplifting spirit.

Hi Born2preach,
Another term is used for a similar phenomenon: Ghost lineage "A ghost lineage is an evolutionary lineage for which no fossil record exists, but the presence of which is inferred from related organisms separated by vast stretches of time".(from Evowiki) Strange. Some scientists prefer "ghost" rather than "Lazarus". In fact both are overstated. The fossil lack is due to gaps, minimum population maintained in an undiscovered yet refuge area and regular low demography below the threshold of fossil record. Denesha

The fossil lack is due to gaps, I can also be taken as strong evidence that not all specimens become fossils (which should be intuitively evident), and very strong evidence that an absence of evidence of "transitional" fossils is not evidence of an absence of transitionals -- as it could easily be the same phenomonon as the {ghost\lazarus} fossil records. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

Thank you Abby,
We could try to complicate a bit more if the gap includes a mass extinction or not. Answers couldn't be simple. Denesha

We could, but it would not be necessary.
Probably the best known example would be the Coelacanth -- where are all the intermediate fossils between prehistoric and modern specimens? Lost in time but not just because of mass extinctions. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

I agree Abby. This classic example is quite good and underscores the incompleteness of our fossil documentation. But if we analyse closely this present case we observe that Coelacanth was probably and gradually becoming in the scope of cryptozoology during the timer-scale. Honestly, we should recognise how lucky we are to observe our day’s biodiversity. I don’t think that Paleontologists in three or four million years (if they will be some) will find any fossils of this fish in our day’s sediment because of the Taphonomic Biases. For those not familiarised with this term, TB are all the filters affecting the incorporation of a past organism in the fossil documentation.
Coelacanth is a good example of huge gap but both fossil and recent related fish are known now. Have your heard about Megachasma. This huge shark was first described in 1976. No fossil form is known.A little known huge fish coming from nowhere. See here for more: http://www.flmnh.ufl.edu/...descript/Megamouth/Megamouth.htm Denesha

yes, I've heard about megamouth (I thought the whale shark was another recent "find" but found it was discovered in 1828).
One would logically think that any specimens that died a natural death would sink to the seafloor and thus fossilization would require sediment to cover and tectonic plate shifting for access and discovery. One wonders how many fossils are buried in the ocean floors.

Unfortunately, there are not many fossils down there. Sedimentation rate is too slow. Most of the material was disintegrated before diagenesis starts (an other biblic word). Our fossil documentation is filled up with holes.
Consider the case that all the early phylogenetic stages of a lineage have been existed only under inadequate fossilisation condition in exception of one species (which we have fossils). If this fossil will fall on a zealous taxonomist hand, he will create a species, a genus, certainly a family and perhaps a superfamily. If the same fossil fall in a evolutionist hand, he will suggest a ghost/lazarus effect to connect this fossil (whatever the spatial & temporal jump invoked) with something known to date AND according to his own perception of this fossil. Both produce a poor scientific result. Denesha

Yes. That biblical words were used by people immersed in a biblical culture is not surprising. If they had used Mandarin or Hindu words that would have been surprising ...
... I will remember this the next time the issue of "missing links" is raised. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist
