NASA's Curiosity found evidence of a fresh water lake having been on Mars.

That's very cool. Thanks for sharing.

Awesome, I love things like this

Evaporated a couple of billion years ago.
Some frog, shrimp eggs can survive for years in the southwest. They live in desert potholes. This is why National Parks and some BLM don't want people tramping through the potholes when they are dry.

Seeds can also last. Hopefully something is still around after 3 billion years.

I read about this the other day - it's very exciting news for us spacenerds.

That was a good read, my theory is all these planets may have been failed versions of our earth that we live on now, they finally got everything right so that all humans and mammals could survive on it . just my 2cent

Interesting! Who would "they" be?

here is your change for your .02cnets

very cool..
can you imagine the reaction.. if there was 1 small fossil imprint in that dried mud.. of a plant! or bug!

Agreed. Right now, we've got decent evidence to suggest that Mars once had conditions that could theoretically support life (as we know and understand it). That's pretty damn exciting - but if/when we get evidence of that life actually existing, arty:

If we are all descended from Martians, it will upset the applecart very nicely. Mars could very well have been wet when life arose here. Big debate about traces of fossil animicules in Martian meteorites. The one in question was found in Antarctica.

Some were really upset when most folks on earth have some of the Neanderthal genome.

I kind of like the idea. Goes with Sagan's "we are all star stuff" I take that to include all life of any kind.

A plant or a bug is a HIGHLY complex organism. I think you'd find trace evidence of billions of less complex organisms before you'd find a fossil of a plant or bug.

Agreed. Right now, we've got decent evidence to suggest that Mars once had conditions that could theoretically support life (as we know and understand it). That's pretty damn exciting - but if/when we get evidence of that life actually existing, arty:

In order for life to exist, you've got to have the right combination of proteins, RNA, and DNA all in the same cell (not to mention the requirement of a highly specific arrangement of amino acids ranging from 50 to thousands in order to make up a protein molecule; and that's for a "simple cell". The probability that just ONE protein containing only 100 amino acids could ever randomly form has been calculated to be about one chance in a million billion). And RNA is required to make proteins, yet proteins are in involved in the production of RNA. Quite the "chicken or the egg" conundrum. Can you imagine the extremely small odds that both proteins and RNA molecules can appear by chance in the same place at the same time? Virtually impossible.

So even if relatively fresh water did exist on Mars at some point, it doesn't necessarily follow that life was there as well.

Agreed. But finding evidence of a substance we know to be required for life (again, at least as we understand it) can make finding evidence of life at least ever-so-slightly more likely.
