Prehistoric ecosystem found in Israeli cave

Wed May 31, 8:10 AM ET

JERUSALEM (Reuters) - Israeli scientists said on Wednesday they had discovered a prehistoric ecosystem dating back millions of years.

The discovery was made in a cave near the central Israeli city of Ramle during rock drilling at a quarry. Scientists were called in and soon found eight previously unknown species of crustaceans and invertebrates similar to scorpions.

"Until now eight species of animals were found in the cave, all of them unknown to science," said Dr Hanan Dimantman, a biologist at the Hebrew University of Jerusalem.

He said the cave's ecosystem probably dates back around five million years when the Mediterranean Sea covered parts of Israel.

The cave was completely sealed off from the world, including from water and nutrients seeping through rock crevices above. Scientists who discovered the cave believe it has been intact for millions of years.

"Every species we examined had no eyes which means they lost their sight due to evolution," said Dimantman.

Samples of the animals discovered in the cave were sent for DNA tests which found they were unique, he said. The cave has been closed off as scientists conduct a more detailed survey.

"This is a cave of fantastic biodiversity," Dimantman said.

This is a great find, and could go a LONG way toward furthering our understanding of the world's biology and evolution.

What I find equally amazing is that, with all the people going through there for the last 5,000 years, that this site is undisturbed. That's pretty incredible.

It's science. Fewer people care or comprehend (or want to comprehend it) than the people who care about or comprehend a story about whatever Britney's doing with her baby today.

While this is a MUCH more worthwhile story, it's buried a page or two back because it's not sexy. It's a sad commentary on our culture, actually. :-/

I think it's sexy as hell! Seriously, I'm fascinated by this stuff. I don't know as much as I would like, but paleontology absolutely keeps my attention.

Sounds a little on the junkish side of Science... flawed logic.

Regardless... it's still interesting.

Yeah, me too, but remember that the bulk of the country has an 8th grade education level.

There's a reason that people like Roseanne Barr have careers.

There is a spieces of fish from Central AMerica(Astyanax fasciatus mexicanus) which lives in caves. It also is said to evolved to have no eyes seeing it lives in pitch dark caves it has no need for eyesight. Its coloration is a pinkish hue almost albino, evloution is an amazing thing.

I have been fortunate enoughto have bred and cared for this species of fish, the eye sockets are almost scared over as if they at one time had eyes. A very interesting fish.

The University of Maryland had conducted an experiment with the Astyanax fasciatus mexicanus. To give you the jist of the story the implanted lenses into a Astyanax fasciatus mexicanus from a Astyanax faciatus(a close eyed realitive) and the Astyanax fasciatus mexicanus began to regenerate eyes. Alot of people then questioned what they did and how they came to conclusion that the fish had once had eyes. The debate was really up for discussion for a while until. A fish farm in Florida who has raised to Astyanax fasciatus mexicanus for the last 40 years found an amazing discovery. The Astyanax fasciatus mexicanus they kept in breeding ponds outdoors were starting to develop eyes. While the ones that they raised indoors in massive indoor ponds were not.


So its really not junkish or flawed science, it has been proven.



Here are some pics of the fish

Let's not start a debate over the Theory of Evolution... :*)
