Última Animal emergence during Snowball Earths by thermosynthesis in submarine hydrothermal vents 17 Anthonie W. J. Muller. Darwin already commented on the lateness in the fossil record of the emergence of the animals, calling it a valid argument against his theory of evolution^1^. This emergence of the animals (metazoans: multicellular animals) has therefore attracted much attention^2-5^. Two decades ago it was reported that extensive global glaciations (Snowball Earths) preceded the emergence^6-7^. Here we causally relate the emergence and the glaciations by invoking benthic sessile^8-11^ thermosynthesizing^12-13^ protists that gained free energy as ATP while oscillating in the thermal gradient between a submarine hydrothermal vent^14^ and the ice-covered ocean. During a global glaciation their size increased from microscopic to macroscopic due to the selective advantage of a... Tipo: Manuscript Palavras-chave: Developmental Biology; Evolutionary Biology.
