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.
Growing up in Hampton, the face of science was brown like mine.
Science can destroy religion by ignoring it as well as by disproving its tenets. No one ever demonstrated, so far as I am aware, the nonexistence of Zeus or Thor, but they have few followers now.
When I am in the company of scientists, I feel like a shabby curate who has strayed by mistake into a drawing room full of dukes.
The legends of fieldwork locate all important sites deep in inaccessible jungles inhabited by fierce beasts and restless natives, and surrounded by miasmas of putrefaction and swarms of tsetse flies.
My study is NOT as a climatologist, but from a completely different perspective in_x000D_ which I am an expert … For decades, as a professional experimental test engineer, I have analyzed experimental data and watched others massage and present data. I became a cynic; My conclusion - 'if someone is aggressively selling a technical product who's merits are dependent on complex experimental data, he is likely lying'. That is true whether the product is an airplane or a Carbon Credit.
Even if I stumble on to the absolute truth of any aspect of the universe, I will not realise my luck and instead will spend my life trying to find flaws in this understanding - such is the role of a scientist.
