Brain evolution of fossil fish and the first tetrapods
Public talk by Dr Alice Clement from Flinders University
Fish gave rise to the first terrestrial vertebrates (tetrapods) some 400 million years ago. This greatest ‘step’ in evolution occurred during a period known as the Devonian. The changes that happened in their bodies over deep geological time can be studied via spectacular fossils, modern scanning techniques and comparison with living species. In doing so, we have uncovered some secrets of early brain evolution in fish and discovered what the brains of the first tetrapods, our ancestors, looked like.
Dr. Alice Clement’s research is multidisciplinary encompassing evolutionary biology, vertebrate palaeontology & ichthyology.
She mainly focuses on sarcopterygian fishes (known as “lobe-finned” fishes, such as coelacanths and lungfishes) and the earliest tetrapod-like fishes. Her current research topics include palaeoneurology (fossil brains), 3D anatomy, phylogeny & the evolution of terrestriality -such as the development of limbs from fins, and the appearance of air breathing.
In particular, she uses synchrotron & conventional tomography to create 3D models of fishes and tetrapods; ranging from early stem members of Devonian age to living animals.
