PhD student position in Historical Geology and Palaentology

Overview

Origins of Proterozoic-Cambrian photosynthetic microbiota
Starting date: Open from the closing date for applications.
Unicellular, organic-walled photosynthetic microbiota (prokaryotes and eukaryotes) diversified at an increasing rate through the Proterozoic and in the Cambrian explosion. Their phylogenetic relationships are still poorly understood because their morphology is not always sufficient to infer their systematic position. Studies of phenotypical features, combined with cell wall ultrastructure, biogeochemistry and biomarkers may help to unravel their biological affinities. More precise placement within a geologic time frame will allow the cause-effect relationships between evolving photosynthesing (primary producers) and forthcoming heterotrophic biota (consumers) versus global environmental change to be better understood.
