It’s estimated that there are an unimaginable 10 million different species on Earth. What are they all? Why are there so many? And how do we know what exists (and what doesn’t)? Through discussion, games and live drawing, biologists Adam Hart, Simon Watt and Hana Ayoob explore this daunting diversity of life, and inspire with some arty science.


Adam Hart is a biologist, broadcaster and author. He is Professor of Science Communication at the University of Gloucestershire where he splits his time between teaching, research into insects, ecology and African conservation, and science communication to all audiences. He is a regular presenter for BBC Radio 4 and World Service and has also co-presented documentaries for BBC4 and BBC2. His most recent popular science book is Unfit for Purpose (Bloomsbury), which explores how human evolution clashes with the modern world.

Hana Ayoob is a science communicator and illustrator. She enjoys bringing people together to enjoy exploring the world around them. Hana has a background in Zoology, and will draw and talk about animals whenever possible.

Simon Watt is a biologist, writer, science communicator, comedian and TV presenter. He performs through his “comedy with a conservation twist” show, The Ugly Animal Preservation Society.
