Friday Cephalopod: Epic Battle!

It’s called a Black-Waved Flannel, but none of us are fooled. We know where that came from. It’s probably finished consuming its brain meal and is looking for a new host.

The oldest evidence for microbial life has been found in Greenland, with fossilized 3.7 billion year old stromatolites (layered bacterial colonies) found in the rocks. Here’s what they look like: And here’s the abstract of the paper: Biological activity is a major factor in Earth’s chemical cycles, including facilitating CO2 sequestration and providing climate feedbacks.…
