Baboons are invoked as a comparative example in the book’s argument that natural selection favors gene-level self-interest, not as a species whose behavior is documented in detail. The author explicitly cautions that their conduct cannot, by itself, establish a general claim about human nature: the proposed explanation begins with how selection works, then predicts what observers should find among baboons, humans, and other animals.

Role in the Argument

The book likens its evolutionary reasoning to making cautious inferences about a person who has survived and prospered in a competitive environment. Animals, including baboons, are described as machines created by genes that have persisted through competition. From this starting point, the author argues that successful genes should generally be expected to show ruthless selfishness, which will usually produce selfishness in individual behavior. Under particular circumstances, however, genes may achieve their own propagation through limited altruism by individual animals.

This distinction prevents the baboon example from carrying more weight than the evidence allows. The author says the book is not a descriptive account of baboon behavior and does not reason that baboons are selfish, therefore human beings probably are too. Rather, the theory generates an expectation about organisms shaped by natural selection; observations of baboons and other animals would test or complicate that expectation. If their behavior proved genuinely altruistic, the result would call for explanation rather than be dismissed as a counterexample.

Behavior and Evolutionary Explanation

The book defines altruism and selfishness by their effects on survival prospects, not by an animal’s subjective motives. A baboon would count as altruistic if its behavior raised another’s welfare at a cost to its own; selfish behavior would have the opposite effect. Since long-term effects can be difficult to establish, apparent altruism is a cautious description: an act may look costly to its performer while benefiting another, yet closer examination may show that its survival effects differ from what first seemed evident.

The author also separates individual conduct from the level at which evolutionary success is being explained. Individual animals may appear to sacrifice their own interests, but the book’s central claim is that such behavior can still be accounted for through the effects of genes on their continued representation in the gene pool. Baboons therefore serve as one of the creatures whose behavior the theory invites readers to examine, not as proof that every individual act is selfish or that animals consciously pursue genetic goals.

Genes, Behavior, and Limits of the Example

The account does not treat a gene as an independent designer of an animal’s actions. Genes interact with one another and with the environment during development; even a convenient expression such as a gene for a behavior refers to a tendency to influence an outcome, not a gene that single-handedly builds a complex trait. The animal’s behavior is likewise presented as if it followed a pre-programmed policy, a way of describing the consequences of selection rather than conscious calculation by the animal or its genes.

The book further insists that its account is explanatory, not a moral instruction. Gene-level selfishness does not establish how humans ought to behave, and the author argues that people can learn generosity even if biological nature offers little support for it. In this framework, baboons help mark the scope of a biological argument: their inclusion connects human beings to other products of natural selection, while the explicit warning against treating them as a behavioral template keeps the comparison from becoming a simplistic judgment about either species.
