For me, the level at which natural selection causes the phenomenon of adaptation is the level of the replicator - the gene.
Interpretation
This quote suggests that genetic material is the fundamental unit that drives evolution and adaptation through natural selection.
Richard Dawkins emphasizes the importance of genes as the core entities responsible for the process of natural selection and adaptation. By referring to the gene as the 'replicator,' he highlights that it is not just the organisms themselves that evolve, but it is the genes that are passed down and modified over generations that shape the characteristics of life forms through evolutionary processes.
In practice
In a science lecture discussing evolutionary biology, this quote can highlight the role of genes in natural selection.
No educated person believes the Adam and Eve myth nowadays, but it's surprising how many parents think that it's somehow fun to pass on this falsehood to their children...I would want to argue that the truth of evolution is more interesting and more poetic
If the history-deniers who doubt the fact of evolution are ignorant of biology, those who think the world began less than ten thousand years ago are worst than ignorant, they are the deluded to the point of perversity.
The population of the U.S. is nearly 300 million, including many of the best educated, most talented, most resourceful, humane people on earth. By almost any measure of civilised attainment, from Nobel prize-counts on down, the U.S. leads the world by miles.
When you make machines that are capable of obeying instructions slavishly, and among those instructions are 'duplicate me' instructions, then of course the system is wide open to exploitation by parasites.
Even if not a single fossil has ever been found, the evidence from surviving animals would still overwhelmingly force the conclusion that Darwin was right.
The bitter hatreds that now poison Middle Eastern politics are rooted in the real or perceived wrong of the setting up of a Jewish State in an Islamic region. In view of all that the Jews had been through, it must have seemed a fair and humane solution. Probably deep familiarity with the Old Testament had given the European and American decision-makers some sort of idea that this really was the historic homeland of the Jews.
An experiment is a question which science poses to Nature and a measurement is the recording of Nature's answer.
Sometimes the probabilities are very close to certainties, but they're never really certainties
The energy requirements for interstellar travel are so great that it is inconceivable to me that any creatures piloting their ships across the vast depths of space would do so only in order to play games with us over a period of decades. If they want to make contact, they would make contact; if not, they would save their energy and go elsewhere.
I have lived much of my life among molecules. They are good company. I tell my students to try to know molecules, so well that when they have some question involving molecules, they can ask themselves, What would I do if I were that molecule? I tell them, Try to feel like a molecule; and if you work hard, who knows? Some day you may get to feel like a big molecule!
And anyone who thinks they can talk about quantum theory without feeling dizzy hasn't yet understood the first thing about it.
It is my supposition that the Universe in not only queerer than we imagine, is queerer than we can imagine.
