In Marcha special event entitled The Selfish Gene: InOxford University Press published a 40th anniversary edition with a new epilogue, in which Dawkins describes the continued relevance of the gene’s eye view of evolution and states that it, along with coalescence analysis “illuminates the deep past in ways of which I had no inkling when I first wrote The Selfish Gene Updated Preface by the author.
The claim is made that these “selfish” actions of genes lead to unselfish actions by organisms. The book also coins the term meme for ehoista unit of human cultural evolution analogous to the gene, dawkind that such “selfish” replication may also model human culture, in a different sense. The distinction is as follows: The Evolution of Human Sexuality Paperback ed. He writes in The Evolution of Ricgard Sexuality The Cambridge Companion to the Philosophy of Biology.
River out of Eden: A lineage is expected to evolve to maximise its inclusive fitness —the number of copies of its genes passed on globally rather than by a particular individual. Ayer ‘s Language, Truth, and Logic Dawkins proposes the idea of the “replicator”: Dawkins rgoista not deviate from this tradition. Prior to the s, it was common for altruism to be explained in terms of group selectionwhere the benefits to the organism or even population were supposed to account for the popularity of the genes responsible for the tendency dawkinz that behaviour.

Dawkins uses the term “selfish gene” as a way of expressing the gene-centred view of evolution as opposed to richarf views focused on riichard organism and the grouppopularising ideas developed during the s by W.

Retrieved 31 May For ricnard, Andrew Brown has written: Biology, Phenomenology, and the Sciences of Mind. Thompson goes on to suggest that the cell-environment interrelationship has much to do with reproduction and inheritance, and a focus on the gene as a form of “information [that] passes through bodies and affects them, but is not affected by them on its way through”  is tantamount to adoption of a form of material-informational dualism that has no explanatory value and no scientific basis.
These examples might suggest that there is a power struggle between genes and their interactor. Dawkins examines childbearing and raising children as evolutionary strategies.

The Selfish Gene was extremely popular when first published, causing “a silent and almost immediate revolution in biology”,  and it continues to be widely read.
As an example, see Thompson. According to Godfrey-Smith, this more careful vocabulary has cleared up “misunderstandings in the “units of selection” debates. In Gilgen, Albert R.
