High-fidelity modular skeletons authenticate a Cambrian origin for Bryozoa
13+ hour, 26+ min ago (1518+ words) The major animal body plans originated during the Cambrian explosion, yet the phylum Bryozoa has remained a conspicuous exception to this pattern1. The initial discovery of Protomelission gatehousei2 provided compelling evidence for a Cambrian origin for the Bryozoa, together with other major…...

Protobiosignatures in the framework of early life detection - Nature Astronomy
1+ week, 6+ day ago (289+ words) Experimental investigations of biomorphs " abiotic structures that mimic the morphology of life " provide essential control data for biosignature interpretation. On planets where chemistry never quite became life, these experiments may hold the key for detecting and understanding extraterrestrial origin of…...
Early fossil eukaryotes were benthic aerobes
2+ week, 13+ hour ago (1513+ words) The evolution of the eukaryotic cell paved the way for the emergence of all complex life on Earth. Despite its significance, the environmental context of early eukaryote evolution is largely unknown1, 2. Here we use the geological record to reconstruct the habitats…...
