Celebrating the International Darwin Day, Biology students and the Botanical Garden’ s staff of the Central University of Las Villas will present a video about the evolution process and some of the Darwin’ s books simultaneously. Around the midday, actions will occur in the Central Library, in the specialized classroom of the Botanical Garden, in the School of Agronomy and in a junior school near the campus. Our objective is to create an informal and pleasant debate with children, university students, teachers and services workers concerning not only about evolution, but else about biodiversity and how to change our social perception and our way to life in harmony with nature and with other people.
