Antelopes

Antelopes are presented as prey in an example of how conflict between species can settle into stable, contrasting behavioral strategies. Their flight from lions is not treated as a moral failing or as a sacrifice for the species; it is an outcome of unequal interests and the evolutionary costs of fighting back.

The Conflict with Lions

The conflict begins with incompatible uses for the antelope’s body. A lion’s genes benefit when the body becomes food for the lion’s survival machine; the antelope’s genes benefit when that same body remains functioning muscle and organs. The animals therefore have sharply opposed interests over the same resource, even though the encounter is not usually described as competition.

This framing shifts attention from a generalized “good of the species” to the consequences of a particular interaction. The lion and the antelope are not competing for a resource they can share: the lion’s use of the antelope’s body and the antelope’s continued use of it cannot both prevail.

Why Antelopes Run

The book explains the contrast between predator and prey through the idea of an evolutionarily stable strategy. In encounters between different species, asymmetries are often stronger than those between members of the same species. Where such asymmetries exist, strategies conditional on them—such as running when smaller and attacking when larger—are likely to evolve.

A lion’s pursuit and an antelope’s escape have, over evolutionary time, become complementary specialties. Their divergence has amplified the original imbalance: lions have become proficient at chasing, while antelopes have become proficient at getting away. A mutant antelope that stood and fought would be less successful than rivals that fled. The result is not a single decision made by an individual antelope, but a pattern shaped by the comparative success of alternative strategies.

What the Example Shows

Antelopes help illustrate how a stable pattern can emerge from conflicting interests without requiring a group to act as a unified whole. Their relationship with lions is used to show that, when the contest is sufficiently asymmetric, conditional responses can persist and opposing species can become increasingly specialized in their respective roles.

The example also reflects a broader caution in the book’s method: animal stories illustrate concepts, but are not by themselves serious evidence for a general claim. The antelope’s flight serves as an illustration of the proposed logic of selection and strategy, rather than a standalone experimental demonstration.
