Last year, a new and unusual species of rodent was discovered in Laos, called Laonastes aenigmamus, or kha-nyou. Photos of the skull and an 11 million year old fossil can be found in "Laonastes/Diatomys/kha-nyou/rat-squirrel", on Pharyngula.Laonastes/ Diatomys/ kha-nyou/ rat-squirrel

This thing needs a better name. How would you like to go through life being named for two other species?
Let's have some suggestions for names.

Losangelestes Fafarmanus IDioticus, commonly known as the "Larry Rat." Never mind, that would be redundant.

This creature can't possibly be related to Larry Farfromaman: it's too cute.

I think the Intelligent Designer decided that Laotians were missing out on a tasty treat for too long.

"R.E" stands for Religious Education. Not exactly sure what GCSE stands for, I'm sure a Brit will help us out. It's a national standard curriculum for secondary education, apparently.
Rolf Manne · 10 March 2006
I didn't know either and googled. This is what I found:
GCSE stands for General Certificate of Secondary Education.
It is explained here.

The UK school system is as follows:
1) Primary school from age 5 to 11 - no important exams
2) Secondary school from 11 to 16, culminating in GCSEs (General Certificate of Secondary Education). Most people take about 8 GCSEs iirc
3) Sixth form or college from 16 to 18, culminating in A-levels (Advanced Levels). Most people take about 4 A-levels.
4) University from 18 to whenever.
Just to shake things up, recently they've introduced a new set of exams at age 17, called A/S levels (Advanced Subsidiary Levels). Two A/S levels = one A-level. It's all a bit confusing and generally results in kids being horribly over-examined.

I notice that this species isn't called a "living fossil" as creationist orginisations usually like to put it. I'm positive over the next few days AIG will have an article on their website about this find presenting a problem for evolutionists. Have a look at their views on the Jurassic beaver story which was covered here a week or so ago.
RE. GCSE. When I was a teenager in the 1970's they were called GCE's then and there was no such thing as AS levels just O and A levels. A pass at O level then was a grade between 1-6 with 7,8 and U (ungraded) being fails. A level grades were A,B,C, O and F with A,B, and C being passes and F a fail. An O grade, while not being a pass was still useful because some third level courses required a subject to be studied to A level but did not necessarily ask for a pass. How times have changed.
I think my geology teacher would have been horrified, if he where still alive, at the thought of "flood geology" even being discussed in class. I'm sure he would have refused.

The name of this topic doesn't fit too well in the "Recent Comments" box on the main page - that long string of nonblank characters causes it to run outside the box.

how about "scandentoid" (looks like a tree shrew)?
John Wilkins · 10 March 2006
A couple of points about the journalism reporting this:
1. The species was not found in the fossil record 11 million years ago, other members of the "family" were. "Family" is a Linnean rank that has absolutely no objective significance whatsoever. It just means that the evolutionary group of which this species is a member had relatively close sister taxa that some biologist or paleontologist found similar enough to group that way.
2. Even if the same "species" were identified as being around 11 million years ago as the one found today, that doesn't make it the same species. Let me explain. There is a problem identifying reproductively isolated species from fossil taxa because the biological properties that make one population isolated from another do not fossilise. It may very well be that the fossil form was a distinct biological species even if the two are similar enough to call the same "paleospecies" or "chronospecies". Form is one indicator, but not a sufficiently rich one, to identify actual isolated reproductive pools.
Off to curmudgeon about something else now...

Re John's comment 85874. I was going to say something similar but not having done biology I decided to refrain from doing so.
I've read a number of articles that basically say the same thing John i.e. that the so called term "living fossil",that creationists often use to describe a discovery such as this, is really a misleading one. For instance the fossilised coelacanths (another example) were an entirely different species to the ones that were discovered alive a few decades ago. I wonder how many creationist followers realise this ?
Flitcraft · 11 March 2006
Dean,
The Guardian piece you link to and the coverage of this story in the media in general has been pretty useless. It seems to boil down to people being unable to tell the difference between teaching Creationism and teaching history of science.
Here is the actual syllabus that sparked the story
http://www.gcse-science.com/file_downloads/pgd_files_245_10.pdf
The relevant bits are pp.34-35. It covers things like debunking Lamarckism and examining the reception Darwin got at the time. All very handy stuff. The exam board itself is very clear:
Creationism and 'intelligent design' are not regarded by OCR as scientific theories. They are beliefs that do not lie within scientific understanding.
http://www.ocr.org.uk/OCR/WebSite/docroot/newsupdates/newslist/detail.jsp?server=PRODUKTION&site=OCR&oid=27616"
I'm a bit concerned that people are going off half-cock over this and that it may lead to them being taken less seriously when they address real threats like the Vardy Schools.

Dean Morrison · 11 March 2006
Flitcraft - I've read through the syllabus you mentioned and it seems fine to me.
In fact it's better than the old one which specifically mentions creationism (as a historical position)
I'm confused to see how this story got started - and the OCR have given a pretty clear clarification:
OCR rejection of Creationism and Intelligent Design
Flitcraft · 11 March 2006
Dean - It seems to have broken in the Murdoch press a day earlier than everywhere else: in 'The Times' and 'The Sun' of March 9th (those are the dates given for those stories on Google News). Looks like a straightforward case of bad reporting there, followed by lazy reporting as the rest of the media followed suit. They were probably trying to dig something up in the wake of the Jacqui Smith statement, and ended up manufacturing a story to fit.
My apologies to the rat-squirrel, since he has such a big chewing muscle, perhaps he should be called Chewie? Then obviously he would be the Chewbacca squirrel.

Laonastes aenigmamus, the Laotian rock rat, is the only known survivor of a morphologically distinctive family of rodents; check out the distinctive jaw. It is thought to be nocturnal, and no one knows how many of them there are. "Family" is a keyword here. As John points out, this is not the same species that existed many millions of years ago. Wiki already has it covered, along with many other species, but amazingly they missed Gracilidris pombero. Wiki also covers term like "Lazarus taxon" and "living fossil".

That got me to wondering... What are creation scientists doing these days as far as field research? What kind of thing(s) are they looking for? How are they going about examining the evidences of nature to confirm or dis-confirm their theories on the mechanisms of biological diversity? Where are they conducting their research? How successful (or not) have they been? Do they publish their findings? If so, where? Who funds their research?

this is a little late in response to Gorbe. Here are the answers to his questions. Nothing, Nothing, Nothing, Nowhere, They don't care, No, Nowhere, What research? I hope I've been helpful. TPFD.
