Topic description:
For the last two hundred years, the developmental series has served as the main means of visual representation in embryology. The typical developmental series consists of a sequence of images each depicting a different stage in the genesis of the embryo. Over the last two decades, novel techniques of imaging have been introduced. Techniques such as the “in toto” representation or “multiview in vivo imaging” of the embryogenesis of an organism aim at tracing every single cell, from every angle, in every moment throughout the entire course of development. The ultimate aim is a predictive computational model of embryogenesis.

In my paper, I will discuss the impact of new techniques of imaging and computing embryogenesis on the biological notion of development. In particular, I will ask what the claim of a) conceiving of the totality of embryogenesis and b) of its ‘in vivo’ representation entail and will argue that the new imaging techniques shift the border between where the representation of life begins and its reality ends. As I will show, this not only has consequences for the concept of time at the heart of the notion of development, but also of the living as put forward in current developmental biology.
