Life is simply the reification of the process of living.
Ernst MayrRead
Evolution ... is opportunistic, hence unpredictable.
Interpretation
Evolution is driven by chance events, making it unpredictable.
The quote by Ernst Mayr emphasizes that evolution is not a linear or predetermined process; rather, it takes advantage of random opportunities that arise in the environment. This unpredictability means that evolutionary outcomes can vary widely based on the specific circumstances and chance events, illuminating the complexity and dynamism of life on Earth.
In practice
This quote can be used in a discussion about the complexities of environmental adaptation in biology.
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.
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.
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.
There is no scientific reason to think that we, even with space travel, are going to survive as a species for ever, certainly not by biting off the hand that feeds us, which is exactly what we are doing.
Civilization as it is known today could not have evolved, nor can it survive, without an adequate food supply.
If it were only a few degrees, that would be serious, but we could adapt to it. But the danger is the warming process might be unstable and run away. We could end up like Venus, covered in clouds and with the surface temperature of 400 degrees. It could be too late if we wait until the bad effects of warming become obvious. We need action now to reduce emission of carbon dioxide.
There's a small worm called Loa Loa Filariasis. This parasite can survive in one environment exclusively- namely, underneath the skin and inside the eyes of human beings. Children and the elderly in tropical regions (usually the poorest) are the most widely affected. A painful, slow death is virtually certain. The worm can actually live in the host for 17 years before the host finally dies.
The scientific observer of Nature is a kind of mystic seeker in the act of prayer.
There's something really beautiful about science, that human beings can ask these questions and can answer them. You can make models of nature and understand how it works.
