The conflict ge in part over defining concepts:. Dawkkns claim still is made by some that it would take only a single individual with a tendency towards more selfish behaviour to undermine ricard population otherwise filled only with the gene for altruism towards non-kin.
It was accompanied by a festschrift entitled Richard Dawkins: Dawkins thinks the use of ’cause’ as a statistical weighting is acceptable in common usage. 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.

In later work, Dawkins brings evolutionary “selfishness” down to creation of a widely proliferated dawkims phenotype.
