I spoke at a meeting organised by Nick Lane at Chichley Hall, home of the Kavli Royal Society International Centre, Buckinghamshire.
This was a wonderful meeting, full of diverse talks and with a lot of people interested in major evolutionary transitions on the planet.
The programme for the meeting can be picked up here.
I gave a talk on the origins of the eukaryote cell. The event was not video recorded, but it was audio recorded and the recording is being archived.
