Critters, critters, everywhere
POSTED AUGUST 29, 1996 The discovery of traces of single-celled organisms in a meteorite from Mars reminds us that life can inhabit some pretty strange places. On Earth, life has recently been discovered on the ocean floor, in mile-deep rock, and in temperatures above the boiling point of water.

Let's start with the most amazing news of all -- the signs of life on Mars 3.6 billion years ago. Thirty years ago, nobody believed life could survive near the boiling point of water. Then a microbiologist began roaming the hot springs at Yellowstone National Park. Nice work if you can get it?

The batteries on these squid don't ever go flat -- not with their clever survival strategy.

Come to think of it, there are plenty of other peculiar things going down in the ocean. Here's a quick sampler. Meiofauna live between grains of sand, on the Greenland ice cap, and in the leaves of moss: phenomenally diverse -- and astonishing.

I hate to mention pure science, but the treasure-trove of newly found bugs n' stuff is giving us a new view of the biosphere. Want to know the rotten truth? Genetically speaking, people and fungi are close relatives.

These humanoids emerged from their bizarre habitat to discuss strange critters.
