The view of The Selfish Gene is that selection based upon groups and populations is rare compared to selection on individuals. With altruism this will happen only if the affected individual is a relative of the altruist, therefore having an increased chance of carrying the gene.

Growing Up in the Universe Dawkins vs. Updated Preface by the author. Dawkins examines childbearing and raising children as evolutionary strategies. Archived from the original on 15 June Dawkins describes God as an old idea which probably arose many times, and which has sufficient psychological appeal to survive effectively in the meme pool.
For some, the metaphor of “selfishness” is entirely clear, while to others it is confusing, misleading, or simply silly to ascribe mental attributes to something that is mindless. Although Dawkins agrees that groups can assist survival, they rank as a “vehicle” for survival only if the group activity is replicated in descendants, recorded in the gene, the gene being the only true replicator. 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.

Please log in to add your comment. A Darwinian View Paperback ed. Dawkins’ later formulation is in his book The Extended Phenotypewhere the process of selection is taken to involve every possible phenotypical effect of a gene.
It is the gene, the unit of heredity. 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 towards that behaviour.

Hamilton ‘s argument for kin selectionthat genes for behaviour that improves the survival chances of close relatives can spread in a population, because those relatives carry the same genes.
