Rotifers - Just add water!

These organisms can experience the harshest conditions, yet amazingly still come back to life by just adding water; and they have many other interesting features as well!

Great they are getting DNA from everything around them. So after earth is wiped of all life, they will kind of restart it when the conditions are right. 8-)

Nature is indeed awesome, though I personally think that water is just Tellus' basic life provider. However, in other galaxies they might have other liquids that they're made up of, it doesn't have to be water. Still, very interesting short doc!

If I was Rotifer I would prefer beer. >:)
But interesting vid.
Would be a nice topic for SF novel.

I don't collect achievements.
I'll leave that to witless idiots such as yourself.
Your achievements page looks very impressive. ROFLMFAO :D

The really interesting thing about Bdelloid Rotifers is that they are asexual, and have been for millions of years.

Normally, when a species drops sex, it goes extinct after a short while, for a number of reasons centered on a lack of genetic diversity.

It seems the rotifers escape this fate much like bacteria do - taking genes from the environment to try on for size.

I've seen elsewhere, too, that their little drying-up trick helps them combat a particularly pernicious fungus. After a couple weeks without water, the rotifers remain viable, but the fungus dies completely. Without that trick, the fungus is almost 100% fatal.

Studying the smallest organism is always a great step into understanding and applying science. Some of these specimen have qualities no other creature(including ourselves) have in our dna. Good video

and this is why I study biology :)

#(removed comment) Really too generalized. Also the theory you mention doesnt really make sense since the eldest organisms are unlikely to even have posessed DNA but only RNA. The permanent version came later. Also, things like DNA splicing werent there at start either.

The human genome relies a lot on splicing to produce the very diverse proteins. A microorgansism has hardly any introns and therefore needs no splicing. Those on off swithces you mention are there, but its really not that simple ;)

Why is NASA trying so hard to find water on Mars? If they can, why not send a rocket with those ( dead looking ) organisms to Mars? Put them on the Mars surface in an enclosed area, and look for any sings of life. However if I can come up with this, the scientists of NASA probably already outdated this idea. :S

Lack of reproduction would be true for many larger species.
Most species on earth evolved from Asexual RNA strings and thus gained sex rather then losing it.

Let's put those on a rock, and send them to outer space, wait for them to grow into an intellegent life form capable to send messages into space.
