Workshop : Does individual evolve through time?
21 novembre 2019 11:30 - Room A1

If time is perceived through causes-effects relationships, we will see that, among cells constituting an individual, same causes generate same effects as among individuals constituting a genealogical lineage. The most recent biology indicates that, contrary to what we have learnt at school, individual's time is the same as evolutionary time. Natural history trains us to play with scales of time and space to understand the diversity of natural phenomena; nevertheless if natural selection is understood as a stabilizing phenomenon, it occurs through a time which is common at all spatial scales. As a consequence, an individual is a historical trajectory of a population of cells, as much as a species is a historical trajectory of a population of individuals.
