NOVA：极端动物武器从龙虾的爪子和犬齿到蜜蜂的刺和蛇的毒牙，每个生物都依赖于武器。但是有些人被武装到极致，这是没有实际意义的，无论是拥有40磅重的鹿角架子的公牛麋鹿，还是有比自己的身体还大的角的小犀牛甲虫。是什么解释了会导致动物减慢速度甚至损害健康和营养的巨大牙，角和爪子？NOVA调查了大型武器的谜题，并揭示了有关触发动物军备竞赛的大胆新理论。在像be虫和剑齿虎，虾和大象这样的生物中，相同的隐藏因素触发了种族，一旦开始，这些军备竞赛就以完全相同的方式展开。加入科学家们，他们破解了构成自然基础的秘密生物密码。NOVA: Extreme Animal WeaponsFrom lobster claws and dog teeth to bee stings and snake fangs, every creature depends on a weapon. But some are armed to extremes that make no practical sense—whether it’s bull elks with giant 40-pound antler racks or tiny rhinoceros beetles with horns bigger than their body. What explains giant tusks, horns, and claws that can slow an animal down and even impair health and nutrition? NOVA investigates the riddle of outsize weaponry and uncovers a bold new theory about what triggers an animal arms race. In creatures as varied as dung beetles and saber-toothed tigers, shrimp and elephants, the same hidden factors trigger the race and, once started, these arms races unfold in exactly the same pattern. Join scientists as they crack the secret biological code that underlies nature’s battleground.
