Geneticist: Genes, like viruses, have a strong tendency to self-replicate; this has led some biologists to call genes "selfish. " This term is, in this instance, intended to be defined behaviorally: it describes what genes do without ascribing intentions to them. But even given that genes are ascribed no intentions, the label "selfish" as applied to genes is a misnomer. Selfishness only concerns bringing about the best conditions for oneself; creating replicas of oneself is not selfish. Which one of the following, if assumed, allows the geneticist's conclusion to be properly drawn? ['Creating replicas of oneself does not help bring about the best conditions for oneself.', 'Bringing about the best conditions for oneself is less important than doing this for others.', 'The behavioral definition of "selfish" is incompatible with its everyday definition.', 'Biologists have insufficient evidence about genetic behavior to determine whether it is best described as selfish.']
