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
Bringing about the best conditions for oneself is less important than doing this for others.
