1a. Ancient Animals:
Erwin et al. present the origination times of early animals (as old as pre-Cambrian) and estimate that the last common animal ancestor (LCAA?) may have lived ~800 million years ago. Results published in the journal Science:
1b. Ancient Atmospheres:
Scientist from the New York Center for Astrobiology simulate the atmospheric conditions of the early Earth using oldest minerals! Study led by postdoc Dustin Trail, available here:
1c. Weird Life:
