You don't get something for nothing in evolution, so we wanted to see which species invested in weapons over testes. We will now look at whether maximising investment in sexual traits means you pay the price in some other aspect of life. Pheasants, minnows, and bush crickets invested in both weapons and testes, while pinnipeds, such as elephant seals where males are almost five times the size of females , and acanthocephalan a type of worms invested more in weaponry but not testes.
Other examples of males investing in weaponry are antlers in red deer, horns in dung beetles, spurs in pheasants and canine teeth in primates. More from Biology and Medical.
