I will be attending the Royal Society Meeting on New trends in Evolutionary biology: biological, philosophical and social science perspectives. I'll post each of the abstracts and ask for your help in deciding what question to pose to the speakers. Here's the abstract for Andrew Whiten's talk on A second inheritance system: the extension of biology through culture.
By the mid-twentieth century the behavioural sciences could offer only the sketchy beginnings of a scientific literature documenting evidence for cultural inheritance in animals – the transmission of traditional behaviours via imitation and other processes of learning from others (social learning). By contrast, recent decades have seen a massive growth in the documentation of such cultural phenomena, driven by long-term field studies and complementary laboratory experiments. Here I first offer an overview of the major discoveries in this field, which increasingly suggest that this ‘second inheritance system’, built on the shoulders of the primary genetic inheritance system, occurs widely amongst vertebrates and possibly in insects and other invertebrates too. Its novel characteristics suggest it should have major implications for our understanding of evolutionary biology. Two major questions arising are accordingly addressed. One concerns the extent to which this second system echoes or differs from the principal properties of the primary evolutionary system described in the neo-Darwinian synthesis of the twentieth century and its extensions under discussion at this meeting. A subsidiary issue here is how the answers may differ much according to whether the focus is on the massively cumulative cultural evolution distinctive of our own species, or on the forms of cultural transmission documented for other species. The second major, and related, question concerns the extent to which the new discoveries about animal cultural transmission extend evolutionary theory, either in addition to or through interaction with the primary, genetically based inheritance systems.Andrew Whiten is an emeritus professor in the School of Psychology and Neuroscience at the University of St. Andrews (Scotland, UK). I'm curious to see his explanation of how cultural evolution in, say, bonobos, informs us about biological evolution.
Here's a possible question ...
The people living in St. Andrews experience a very different culture than the people living in the suburbs of Dallas, Texas. Both groups have been exposed to Donald Trump since he owns a golf club near St. Andrews but they are likely to react differently to Trump. How will these cultural differences affect the biological evolution of the two groups in Texas and Scotland?
