Abstract
Life sciences became Biology, like Physics and Chemistry, only in the 19th century, when researchers turned to reductive, determinist experimental methodologies. Whereas theories like that of the cell and that of Faktoren-of-inheritance provided the elementary units of life, Darwinism provided the framework for the diversity of life and its evolution. Only towards the second half of the 20th century did biologists realize that once living systems were constructed, it was systems analysis that became the focus of understanding living structures and functions.

Raphael Falk
Raphael Falk is professor emeritus of the Hebrew University of Jerusalem. His experimental work at the Department of Genetics dealt with genetic analysis of chromosome organization in Drosophila and with genetic viability effects of irradiation on populations. In the last decades his interest shifted to the philosophy and history of genetics, with emphasis on what is a gene.
