Multicellular Life Began 1.5 Billion Years Earlier than Thought - Sci News  

Approximately 2.1-billion-year-old fossilized tracks discovered in Gabon suggest the existence of a cluster of single cells that came together to form a slug-like multicellular organism that moved through the mud in search of a more favorable environment.

Aussie mammal the first ‘climate change extinction’ - Hindu 

Australia officially declared a Great Barrier Reef rodent [Bramble Cay melomys] extinct on Tuesday, making it the first mammal believed to have been killed off by human-induced climate change. 

Researchers from Queensland determined a key factor in its disappearance was “almost certainly” repeated ocean inundation of the cay — a low-lying island on a coral reef — over the last decade, which had resulted in dramatic habitat loss.
