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 dimmed outlines of phenomenal things all merge into one another unless we put on the focusing-glass of theory, and screw it up sometimes to one pitch of definition and sometimes to another, so as to see down into different depths through the great millstone of the world.
ZOOLOGY, n. The science and history of the animal kingdom, including its king, the House Fly ("Musca maledicta"). The father of Zoology was Aristotle, as is universally conceded, but the name of its mother has not come down to us.
No one trusts a model except the man who wrote it; everyone trusts an observation, except the man who made it.
When you're in a spacecraft, you need to know what things you can touch and what things you shouldn't touch!
A scientist who is also a human being cannot rest while knowledge which might be used to reduce suffering rests on the shelf.
It turned out that the buckyball, the soccer ball, was something of a Rosetta stone of an infinite new class of molecules.
