In recent times we have made discoveries of Neanderthal art that have helped to completely overturn our perceptions of our closest relative from lumbering oaf to thoughtful cousin.We value culture and therefore we consider it an indication of a higher intelligence like our own.So, is it just us and those like us who exhibit evidence of cultural practice or do we also need to revise our assessment of some of the animals that share the planet with us today?Carl Safina is Professor for Nature and Humanity at Stony Brook University, founding president of the Safina Center, and author of Becoming Wild - he joined Jonathan to discuss animal culture and the evolution of group identities in wild animals which he believes may play a role in biological diversification.
