It is not that genes can ‘decide' to become selfish, but rather that natural selection
preserves genes that are more selfish
. It therefore becomes, over the course of evolution, a gene's nature to be selfish.
Why are genes selfish?
The fundamental argument that The Selfish Gene
What is the theory of the selfish gene?
The fundamental argument that The Selfish Gene makes is that
the natural selection process in the evolution of living beings is not about making the species, community or group secure
. It is about making the individual secure, and the individual is merely a vehicle for its genes.
What is an example of a selfish gene?
Examples include
cytoplasmic male sterility
(see Selfish mitochondria). While mitochondrial and chloroplast genes are generally maternally inherited, B chromosomes can be preferentially transmitted through both males and females.
Is the selfish gene wrong?
Even altruism is interpreted as a sophisticated form of selfish behavior used by an organism to propagate its own genes more effectively. “Let us try to teach generosity and altruism,” Dawkins suggests, “because we are born selfish.”
Is The Selfish Gene worth reading?
The Selfish Gene is
a fantastic book
and gives a very unique perspective on how to think about evolution in terms of the gene. As well as this I do believe that there is great amounts of relevance in reading it to understand evolution, especially kin-selection and altruism which are commonly misunderstood.
Are transposons selfish DNA?
Most selfish DNA is probably the
remains of viruses or transposons
that inserted into the chromosome long ago. … Transposable elements are often termed selfish DNA because they are parasitic DNA sequences that inhabit a host genome.
What do biologists mean by selfish genes?
Dawkins coined the term selfish gene as
a way of expressing the gene-centred view of evolution
, which holds that evolution is best viewed as acting on genes and that selection at the level of organisms or populations almost never overrides selection based on genes. …
Who wrote The Selfish Gene?
The Selfish Gene by
Richard Dawkins
is another. From the moment of its publication 40 years ago, it has been a sparkling best-seller and a scientific game-changer.
Do genes compete with each other?
Genes are competing with each other
, as are individuals, tribes, and species. Yet at every level, they are also cooperating. The success of the human species is clearly due to its ability to cooperate in large numbers; and yet any student of war can attest to its deadly competitive nature.
Is the selfish gene still relevant?
The “selfish gene” theory proposed by Richard Dawkins has been an influential thread in scientific and popular thinking for the past 25 years. …
The debate remains unresolved
because the gene-centered view is, demonstrably, partially valid.
How many copies did the selfish gene sell?
There is no book quite like Richard Dawkins' The Selfish Gene. Forty years after its first publication, the book is still in Amazon's top 10 for both the Genetics and Evolution categories, with
over a million copies sold
and more than 25 translated versions.
Where should I start with Richard Dawkins books?

What is highly repetitive DNA?
Repetitive DNA:
DNA sequences that are repeated in the genome
. These sequences do not code for protein. One class termed highly repetitive DNA consists of short sequences, 5-100 nucleotides, repeated thousands of times in a single stretch and includes satellite DNA.
Why did Francis Crick referred to mobile DNA as selfish DNA?
Mobile DNA elements (or simply mobile elements
Are genes more selfish than individuals?
Genes are not selfish
; they are probably the most cooperative insentient objects you can imagine, engaging in unimaginably complex cooperative projects. Yes, alleles are competitive, but they are chosen strictly on evolutionary merit, and do not conflict directly with each other.
