Prof Denis Noble from the University of Oxford delivers a short lecture presentation for the Kathy Wilkes Memorial Conference held in St Hilda’s College, University of Oxford in April 2018. He tells the story of Dr Wilkes’ important contribution to the philosophy of science in terms of introducing ideas of teleology into evolutionary biology, and how this remains a live and hotly debated issue to this day. The video was recorded in the USA during a research visit by Prof Noble, and edited by VOX. You can read her obituary on The Guardian website.
