Life is simply the reification of the process of living.
Ernst MayrRead
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.
Interpretation
The quote emphasizes the sudden appearance of new species in the fossil record, suggesting gaps in the evolutionary process.
Ernst Mayr highlights a crucial aspect of evolutionary biology, pointing out that the fossil record often shows abrupt appearances of new species rather than gradual transitions from their ancestors. This observation raises important questions about the mechanisms of evolution and biodiversity, indicating that the complexities of life's history may not align neatly with linear evolutionary models.
In practice
In a lecture on evolutionary biology, this quote can illustrate the complexities of speciation.
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.
Evolution ... is opportunistic, hence unpredictable.
Brains are tricky and adaptable organs. For all the 'neuroplasticity' allowing our brains to reconfigure themselves to the biases of our computers, we are just as neuroplastic in our ability to eventually recover and adapt.
Equipped with our five senses - along with telescopes and microscopes and mass spectrometers and seismographs and magnetometers and particle accelerators and detectors sensitive to the entire electromagnetic spectrum - we explore the universe around us and call the adventure science.
Trying to capture the physicists' precise mathematical description of the quantum world with our crude words and mental images is like playing Chopin with a boxing glove on one hand and a catcher's mitt on the other.
Evolutionary psychology is one of four sciences that are bringing human nature back into the picture.
There are no black holes - in the sense of regimes from which light can't escape to infinity. There are however apparent horizons which persist for a period of time.
The significant chemicals of living tissue are rickety and unstable, which is exactly what is needed for life.
