Re: Covergent evolution Mars-Earth

Here is simple life and how it might be able to be quite the problem for man.
NASA grant to study space station fungus

The center has been awarded a $750,000 grant by NASA to increase our understanding of the organisms and investigate ways to stop them.

Every long-term mission has seen a growth of microbes where you don't want to see on the shuttle, Mir, and ISS.

The microbes are a type of fungus or bacteria called a biofilm. They represent a threat in space because they eat through the surfaces they grow on, a process called biodegredation. Biofilm formation also increases the risk of human illness. "It shows up behind control panels and has gotten into heat exchangers and pipe systems. On Mir, they once noticed a pretty bad stench. Looking for its source, they pulled off a panel and found a lot of mold. That was the smell, but it was also consuming plastic cabling in that area,".

That is a risk we do not need on mars...

Re: Covergent evolution Mars-Earth

An interesting video which argues that convergent evolution will be relevant across the universe.

When was the transition from single celled to multi as that is the path to complex life as we know it...sort of the chicken or the egg which came first

Animal embryos evolved before animals

If they're embryos. That's still being argued by the experts.

Stromatolite. A colony of single cell organisms. Held together, growing together. Predecessor to undersea plants?
