Life in the deep-sea has fascinated both scientists and the public for centuries, yet many evolutionary and biogeographic questions remain controversial. The biogeography of the deep-sea today has a historical basis for which the fossil record provides the most direct evidence.
With this project I aim to provide the first survey and analysis of the biogeographic evolution of deep-sea metazoans through the last 50 million years of Earth’s history on a global scale. The deep-sea methane-seep fauna provides an excellent model system for this purpose:
Based on new material from three key areas and using novel analytical approaches, I will focus on four main questions:
