Human fortifications and artillery evolve via the same arms-race logic as animal weapons

Evidence

Artillery and fortifications are manufactured structures, yet they evolve just like the weapons of animals do. Advances in the effectiveness of artillery select for new and better designs of fortresses, and vice versa, in a back-and-forth cycle that can spiral into an arms race. Because fortresses are fixed in place, rivals in these races have defined roles as attackers and defenders, much like animal predators and prey. The final examples pit attacker against attacker, in matched contests more reminiscent of battles between beetles or elk. — Emlen, Douglas J, Animal Weapons_ The Evolution of Battle, 525

Categorization

• XREF: Directly connects to the book’s overarching thesis chapters comparing animal weapons to human military technology across the Iran-Iraq war and Cold War examples. — connects to: Fortification-artillery escalation mirrors predator-prey arms races, not rival contests; Markets and battlefields select among rifle designs like natural selection acts on weapons; Bombers evolved like castles, adding all-around defenses against attackers (+19 more)
• SEED: Angle for an essay: how the attacker/defender role asymmetry in fixed fortifications maps onto predator-prey dynamics, and when the roles collapse into symmetric contests.
