\nTalk Description:<\/strong> A synopsis kindly provided by the speaker is as follows:
\nMammals are among the most widespread and ecologically significant animals on Earth, spanning a huge range of sizes, habitats and ecologies. Modern mammals, from bats to whales to humans, share several anatomical features but the most diagnostic is a unique middle ear containing three bones (hammer, anvil, stirrup). Remarkably, two of these bones once performed a very different function; in all other vertebrates they form the joint between the lower jaw and the skull! The evolution of these elements from load-bearing jaw joint to delicate ear bones has long been upheld as a textbook example of function driving morphological adaptation, with renowned naturalist Sir Richard Owen first describing fossil evidence for this transition in 1845. Questions surrounding this unique evolutionary story have persisted since Owen\u2019s day, including how, and most importantly why, mammals evolved one of their most unique features. This talk will follow the story of the mammalian middle ear from its origin in mammals\u2019 Permian ancestors to the modern day and show how remarkable fossil discoveries from across the world have reshaped our understanding of mammal evolution over these last two mammal evolution over these last two decades. This talk will also cover some of the innovative methods palaeontologists are using to tackle big questions in mammal evolution, borrowing methods from developmental biology, engineering and biomedical science.
