Biology Quotes
It is estimated that well over 99 percent of all the organisms that have ever lived have died without having had offspring. And yet here you are: of all your billions of ancestors over the years, from single cells to worms to fish to reptiles to mammals to primates, not a single one of them died childless. How lucky you are! Of course every blade of grass has an equally long and proud heritage, and every mosquito, and every elephant and every daisy.
Darwin`s idea of evolution by natural selection is, in my opinion, the single best idea that anybody has ever had, because in a single bold stroke it unites meaning with matter, two aspects of reality that appear to be worlds apart. On one side, we have the world of our minds and their meanings, our goals, our hopes, and our yearnings, and that most honored - and hackneyed - of all philosophical topics, the Meaning of Life. On the other side, we have galaxies ceaselessly wheeling, planets falling pointlessly into their orbits, lifeless chemical mechanisms doing what physics ordains, all without purpose or reason. Then Darwin comes along and shows us how the former arises from the latter, creating meaning as it goes, a bubble-up vision of the birth of importance to overthrow the trickle-down vision of tradition.
The human mind, or even the mind of a cat, is more interesting in its complexity than an entire galaxy if it is devoid of life.
There can be no eternal life because the very basis of life is its transient and dynamic nature.
Natural selection is a mechanism for generating an exceedingly high degree of improbability.
For a biologist the alternative to thinking in evolutionary terms is not to think at all.
