Hi slevesque
I have never read any scientific paper on the classification of the modern-day coelacanth compared to the fossil one.
This website has good information on the Coelacanths:
http://www.dinofish.com/
With lots of links to more information (news, history, biology, etc)
DINOFISH.com - COELACANTH Biology and Behavior
DINOFISH.COM - Weird Bodies Frozen in Time
quote:
The classification of coelacanths is a murky business with more than one vairation in the class category, but we'll give it a shot. Kingdom: Animalia, Phylum: Chordata, Class: Pices (fishes), Sub class: Gnathostomata- jawed fishes, Sub class: Teleostei- bony fishes (though cartilaginous, coelacanths are usually classed with the teleosts), Sub class: Sarcopterygii (lobed-finned fishes), Order: Crossopterygii, Family: Actinistia (coelacanths), Gennus: Latimeria, Species: chalumnae and menadoensis.
Note that the modern ones fall into a new genus, Latimeria, not just a new species, compared to the fossil ones.
Enjoy.

Let's try a game ...
Hi again slevesque
Its seems you always see the same analogies in creationist litterature: Tornado in your backyard would produce a boeing 747, mistakes in a blueprint of a house, etc.
Why would you want to consider an analogy made by someone who doesn't understand evolution (or more nefariously, doesn't want you to understand evolution)? Why not ask a biologist?
I've been thinking about this for quite some time, what would be a correct analogy of Neo-Darwinian Evolution (Mutations+natural selection) ?
Let's play a game:
Start with a hundred dice and two people and throw the dice all at once.
The dice represent a breeding population.
Now the two people are the "fitness environments" - in one environment only 1's can survive, while in the other only 6's can survive, so after the first throw all the 1's are collected by the first person, while all the 6's are collected by the second person.
Throw the remaining dice and repeat.
Fairly soon you will have all the dice in either population 1 or population 6, yes?
What you have seen is mutation (the dice throw), selection for fitness to an environment (either 1 or 6), change in the hereditary traits from generation to generation (the proportions of 1's and 6's increase in the total population with each throw of the remaining dice), leading to speciation (the division of the parent population into two daughter populations).
This is how evolution works in a broad sense, however this game is still not perfect, as it does not involve reproduction and death, nor does it involve competition between the daughter populations, so like all analogies, it must be treated as an approximation of what occurs in nature.
Enjoy.
