Twins are special because they can tell us about nature and nurture in human development. From twin studies like TEDS, we know that both are important for every complex human characteristic: each trait is influenced by both genes and environments.

But is that the same everywhere? What if we explore how the balance of nature and nurture varies across a nation like the UK? The spACE project uses statistical and visual analysis to do just that. It shows that the relative importance of nature and nurture really can depend on where we live.


The video above demonstrates the spACE visualisation program that we developed to explore the variation in genetic and environmental influences across the UK. This analysis of TEDS data is described in the following freely available article:
