Painter Girls

Biological gender interacts with environment in ways not fully understood. Identical twin girls separated at birth and reunited decades later have shown both startling similarities and differences. In 2005 Kim Wallen of Emory University noted, "I think the 'nature versus nurture' question is not meaningful, because it treats them as independent factors, whereas in fact everything is nature and nurture." Wallen said gender differences emerge very early and come about through an underlying preference males and females have for their chosen activities.
Girls' education
Girls' equal access to education has been achieved in some countries, but there are significant disparities in the majority. There are gaps in access between different regions and countries and even within countries. Girls account for 60 per cent of children out of school in Arab countries and 66 per cent of non-attendees in South and West Asia; however, more girls than boys attend schools in many countries in Latin America, the Caribbean, North America and Western Europe. Research has measured the economic cost of this inequality to developing countries: Plan International’s analysis shows that a total of 65 low, middle income and transition countries fail to offer girls the same secondary school opportunities as boys, and in total, these countries are missing out on annual economic growth of an estimated $92 billion.
