Molecular mechanisms driving Darwinian evolution
According to the Neodarwinian theory, biological evolution depends (1) on the availability of genetic variants, (2) on natural selection exerted on all available forms of life and (3) on geographical and reproductive isolation. The now available methodology of molecular genetics enables us to explore the molecular nature of genetic variation. It has become clear that many different molecular me...
متن کاملArtificial Chemistry and Molecular Darwinian Evolution in Silico
A simplified model of Darwinian evolution at the molecular level is studied by applying the methods of artificial chemistry. A chemical reactor (chemostat) is composed of molecules that are represented by binary strings, where these strings are capable of a replication with a probability proportional to their fitness. Moreover, the process of replication is not fully precise, there may appear s...
متن کاملDarwinian aspects of molecular evolution at sublinear propagation rates.
Mean fitness is non-decreasing in the symmetry sector of the frequency trajectory followed in competitive replication at sublinear propagation rates (parabolic time course). This sector contains the pairwise symmetric distribution of species frequencies and its neighboring states, and represents at least half the possible states of an evolving sublinear system. States is the non-symmetry sector...

متن کاملUnderstanding the molecular mechanisms driving metastasis
Metastasis continues to be a lethal hallmark of cancer, with most patients dying as a result of the dissemination of the disease to foreign organs rather than as a consequence of the primary tumor. Malignant cells spread from the primary tumor to distant sites, where they resist conventional treatments, proliferate, and cause failure of vital organs. Systemic dissection of the molecular, cellul...
