Evolution of adaptation mechanisms: Adaptation energy, stress, and oscillating death.

In 1938, Selye proposed the notion of adaptation energy and published 'Experimental evidence supporting the conception of adaptation energy.' Adaptation of an animal to different factors appears as the spending of one resource. Adaptation energy is a hypothetical extensive quantity spent for adaptation. This term causes much debate when one takes it literally, as a physical quantity, i.e. a sor...

Epigenetics and Evolution: An Overview

After many years of neglect, the developmental aspect of heredity and its place in evolution are now receiving attention. In this overview, I discuss the relationship between epigenetic inheritance (mainly cellular epigenetic inheritance) and biological evolution. I point to six effects and implications of epigenetic inheritance that are important for evolutionary studies: (i) evolution can occ...

Galaxy Evolution: an Overview

We review recent ideas on the evolution of galaxies. Two models are competing to explain the observational features: the monolithic model in which galaxies assemble at high redshift, and evolve with little influence from the environment, and the hierarchical model in which small galaxies progressively assemble to form bigger objects. We describe the basic features of the model of hierarchical f...
