Fortification-artillery escalation mirrors predator-prey arms races, not rival contests

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 (#expands, via linked claim)

Fortification styles evolved in tandem with ever more effective artillery. Early structures relied on square-sided, protruding towers to provide flanking fire along the walls, but corners proved vulnerable to flying boulders. Below: Later castles had round towers to deflect artillery. Even when struck directly, these towers were less likely to shatter. — Emlen, Douglas J, Animal Weapons_ The Evolution of Battle, 972 (#corroborates, via linked claim)
