There is news about a new bacteria discovered
at nearly 3 miles below the surface, surviving without an ecosystem
and all alone. It is believed to live off of hydrogen and sulfur.
http://abcnews.go.com/Technology/story?id=5998582&page=1
So did it evolve there?
Or has it been there since the Big Bang?
Or is it something common to all the planets subsurfaces?
How could it have just suddenly appeared, say in the last million
years?
What purpose does it serve if it is not part of the food chain?
Why was it created if it serves no purpose?
Could it evolve in another million years to something more
complex?
Is it our ancestor?
Critics are already suggesting that it probably migrated from
the surface to that depth over millions of years.
If so, why don't we see any missing links in between, for example,
in deep caves.
Maybe some bio-caver can get a grant out of this?

Maybe nobody has looked in the right deep cave.
"What purpose does it serve if it is not part of the food chain? Why was it
created if it serves no purpose?:
I'm sure it does have a purpose, just like all those other extinct plants,
animals, etc, that we've managed to callously exterminate. Just because it
doesn't serve man's purpose doesn't mean it doesn't serve a purpose. Just stomp
on a butterfly and then come back in 1000 years and see if that butterfly was
useless.

I won a door prize this year at TCR. It was a Tikkina headlamp.
http://www.campmor.com/images/lights/larger/37764_l.jpg
I would like to say thank you to Whole Earth for donating all the cool
prizes this year.
The Tikkina's number one feature is that it is lightweight.
This headlamp would probably work excellent in "Airman's Cave."
The Tikkina is not a suitable caving headlamp for wet caves, or large
cave passage, and certainly not for really big caves.
The Tikkina would be handy on an overnight hiking trip, and to use around in
your tent.
For $ 23, you could buy a better LED headlamp.
I don't like the switch, and that you can't dim the light, or temporarily
make
it brighter.
I know cavers take lamps like the Tikkina and attach them to the helmet
above,
or to the side of their primary light. That would be fine if you plan to
go
to a dry cave. I will let somebody who does that say more about the
advantages and disadvantages of doing that.
The Tikkina is sold at many outdoor retailers. I bet Academy even
sells it.
In my opinion, the Tikkina and similar lights need to be more rugged.
Perhaps, they could make the helmet bracket out of stainless steel,
or put a rubber coating around it somehow.
I am only going to give it 1 star out of 5.
On a related note,
My theory is that tiny lamps like this will be more practical
someday when the capacity of triple-A batteries becomes
greater. Also, if LED lights ever get more efficient; then this style
of headlamp will become more suitable for caving.
