Sur la piste des origines de la vie Des êtres vivants sont capables de vivre à des températures allant jusqu'à 110, à des profondeurs de près de 3.000 mètres sous les océans, on les appelle les microbes de l'enfer. Using methods such as Dayhoff recoding to reduce compositional bias in the sequences, the positions of these novel lineages were examined critically. This book focuses on particularly interesting sites such as Andean lake microbialites, a proxy of early life since they are characterized by very high UV light, while Alchichica and Bacalar lakes are characterized by high-salt and ...
