Astrobiology of life on Earth.

Environ Microbiol 2021 Apr 5. Epub 2021 Apr 5.

School of Biological Sciences, Department of Microbiology, Southern Illinois University, Carbondale, Illinois, 62901, USA.

Astrobiology is often regarded as the study of life beyond Earth, but here we consider life on Earth through an astrobiological lens. Microbiology has historically focused on various anthropocentric sub-fields (such as fermented foods or commensals and pathogens of crop plants, livestock, and humans), but addressing key biological questions via astrobiological approaches can further our understanding of all life on Earth. We highlight potential implications of this approach through the articles in this Environmental Microbiology special issue "Ecophysiology of extremophiles". Read More

The role of symbiosis in the first colonization of the seafloor by macrobiota: Insights from the oldest Ediacaran biota (Newfoundland, Canada).

Biosystems 2021 Mar 29;205:104413. Epub 2021 Mar 29.

Palaeocreations, Bristol, UK.

The earliest record of animal life comes from the Ediacaran of Newfoundland, including dm scale fossil organisms, most of which are inferred to have been epibenthic immotile eumetazoans. This work introduces the palaeobiology of the major fossil groups in the Newfoundland assemblages including strange fractal-like taxa and addresses some of biogeochemical challenges such as sulfide buildup that could most easily have been overcome by symbiogenesis. Specifically, the epibenthic reclining nature of some of the Ediacaran biota-with their fractal-like high surface area lower surfaces-are considered to have been well designed for gaining nutriment from chemosynthetic, sulfur-oxidizing bacteria.
