Glacial Lakes and their ecosystems
One interesting recent discovery has been that of lakes that have been formed up to 15 million years ago. What's unique about these lakes is that they are found underneath antarctic glacial ice. What's even more mind boggling is that these lakes are known to contain microorganisms. A complete, independent, isolated evolved ecosystem.

Data from ice 3590 meters below Vostok Station indicate that the ice was accreted from liquid water associated with Lake Vostok. Microbes were observed at concentrations ranging from 2.8 ? 103 to 3.6 ? 104 cells per milliliter; no biological incorporation of selected organic substrates or bicarbonate was detected. Bacterial 16S ribosomal DNA genes revealed low diversity in the gene population. The phylotypes were closely related to extant members of the alpha- and beta-Proteobacteria and the Actinomycetes. Extrapolation of the data from accretion ice to Lake Vostok implies that Lake Vostok may support a microbial population, despite more than 106 years of isolation from the atmosphere.

One thing I've always found interesting is...where does the bible describe these ecosystems? Where in the bible does it talk about glaciers? And also, how does the bible account for chemotrophs at the bottom of the ocean in the trenches, these chemotrophic ecosystems have thrived for millions of years outside the need for sunlight.
It is interesting how...theists, igonre these other facts regarding life on earth. I wonder whether Noah had room on his boat to account for glacial micorbes.
More importantly how exactly did the great flood affect antarctic ice? did it melt it? And also, if noah had 2 of every animal on teh boat, then how come is it penguins only live in the southern hemisphere? How did they get there? I know for a fact that Noah's boat didn't get down to antarctica...hmmm......
It's interesting because back then, they had no idea microbes were what caused disease...lol..which is why you don't see it in the bible, proving yet again, how fallacious the bible is.
