Life is simply the reification of the process of living.
Ernst MayrRead
Evolution, thus, is merely contingent on certain processes articulated by Darwin: variation and selection. No longer is a fixed object transformed, as in transformational evolution, but an entirely new start is, so to speak, made in every generation.
Interpretation
Evolution is a process driven by variation and selection, resulting in new beginnings with each generation.
In this quote, Ernst Mayr emphasizes the idea that evolution is not a simple transformation of a fixed object over time, but rather a dynamic process characterized by variation and natural selection. Each generation represents a fresh start, where new traits emerge and adapt to their environments, highlighting the complexity and ongoing nature of evolutionary change.
In practice
This quote can be used in a lecture about evolutionary biology to emphasize the complexity of evolution.
Life is simply the reification of the process of living.
The most consequential change in man's view of the world, of living nature and of himself came with the introduction, over a period of some 100 years beginning only in the 18th century, of the idea of change itself, of change over periods of time: in a word, of evolution.
There are a number of attributes of species and populations that are not of any particular selective advantage to any single individual in a population but that are of great advantage to the population as a whole.
Wherever we look at the living biota … discontinuities are overwhelmingly frequent…The discontinuities are even more striking in the fossil record. New species usually appear in the fossil record suddenly, not connected with their ancestors by a series of intermediates.
Evolution ... is opportunistic, hence unpredictable.
The world little knows how many of the thoughts and theories which have passed through the mind of a scientific investigator, have been crushed in silence and secrecy by his own severe criticism and adverse examination!
Science is the ultimate pornography, analytic activity whose main aim is to isolate objects or events from their contexts in time and space. This obsession with the specific activity of quantified functions is what science shares with pornography.
One of the liberating effects of science fiction when I was a teenager was precisely its ability to tune me into all sorts of strange data and make me realize that I wasn’t as totally isolated in perceiving the world as being monstrous and crazy
Everything was so new - the whole idea of going into space was new and daring. There were no textbooks, so we had to write them.
The best way to conduct research on a larger scale is to make sure everyone knows what everyone else is doing... The sooner the better - start talking to other people about what you're doing. Because that's what will stimulate things the fastest.
... many folks take them seriously because they just 'know' that evolution can never be seen in the immediate here and now. In fact, a precisely opposite situation prevails: biologists have documented a veritable glut of cases for rapid and eminently measurable evolution on timescales of years and decades.
