Today there are two major theoretical frameworks in biology. One is the ‘chemical paradigm’, the idea that life is an extremely complex form of chemistry. The other is the ‘information paradigm’, the view that life is not just ‘chemistry’ but ‘chemistry-plus-information’. This implies the existence of a fundamental difference between information and chemistry, a conclusion that is strongly supported by the fact that information and information-based-processes like heredity and natural selection simply do not exist in the world of chemistry. Against (...) |

Two problems related to the biological identity of living beings are faced: the who-problem (which are the biological properties making that living being unique and different from the others?); the persistence-problem (what does it take for a living being to persist from a time to another?). They are discussed inside a molecular biology framework, which shows how epigenetics can be a good ground to provide plausible answers. That is, we propose an empirical solution to the who-problem and to the persistence-problem (...) |

“ >. Das hiess doch: Wenn du dir gewisse Tatsachen anders denkst,sie anders beschreibst, als sie sind, dann kannst du die Anwendung gewisser Begriffe dir nicht mehr vorstellen, weil die Regeln ihrer Anwendung kein Analogon unter den neuen Umständen haben.”. |

An assessment is offered of the recent debate on information in the philosophy of biology, and an analysis is provided of the notion of information as applied in scientific practice in molecular genetics. In particular, this paper deals with the dependence of basic generalizations of molecular biology, above all the ‘central dogma’, on the so-called ‘informational talk’ (Maynard Smith [2000a]). It is argued that talk of information in the ‘central dogma’ can be reduced to causal claims. In that respect, the (...) |

In the last few years, the lack of a unitary notion of gene across biological sciences has troubled the philosophy of biology community. However, the debate on this concept has remained largely historical or focused on particular cases presented by the scientific empirical advancements. Moreover, in the literature there are no explicit and reasonable arguments about why a philosophical clarification of the concept of gene is needed. In our paper, we claim that a philosophical clarification of the concept of gene (...) |

Historians of molecular biology have paid significant attention to the role of scientific instruments and their relationship to the production of biological knowledge. For instance, Lily Kay has examined the history of electrophoresis, Boelie Elzen has analyzed the development of the ultracentrifuge as an enabling technology for molecular biology, and Nicolas Rasmussen has examined how molecular biology was transformed by the introduction of the electron microscope (Kay 1998, 1993; Elzen 1986; Rasmussen 1997). 1 Collectively, these historians have demonstrated how instruments (...) |
