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.
I have lived much of my life among molecules. They are good company. I tell my students to try to know molecules, so well that when they have some question involving molecules, they can ask themselves, What would I do if I were that molecule? I tell them, Try to feel like a molecule; and if you work hard, who knows? Some day you may get to feel like a big molecule!
If the fate of the universe was decided in a single moment at the instant of the Big Bang , that was the most creative moment of all.
The missing link in cosmology is the nature of dark matter and dark energy.
It is an error to imagine that evolution signifies a constant tendency to increased perfection. That process undoubtedly involves a constant remodeling of the organism in adaptation to new conditions; but it depends on the nature of those conditions whether the direction of the modifications effected shall be upward or downward.
Even though NASA tries to simulate launch, and we practice in simulators, it's not the same - it's not even close to the same.
There does not exist a category of science to which one can give the name applied science. There are sciences and the applications of science, bound together as the fruit of the tree which bears it.
