恐龙之战 第6期:极限生存(6)
Tyrannosaurus Rex...a skull almost one and half metres long. Up to 60 serrated teeth.
霸王龙,头骨有一点五米长。有六十颗锯齿。
Able to cover 5 metres in a single stride.
上下颚开合能覆盖五米的区域。
This is one of the biggest carnivorous dinosaurs ever to walk the earth.
这是地球史上最大的食肉恐龙。
T. Rex has bone-crushing teeth.
霸王龙拥有碎骨巨齿。
They're huge and two or three or four times the strength, for their body size, of any other meat eater.
它们体型巨大,并拥有数倍于其体重以及其他食肉恐龙体重的力量。
But a T. Rex is born into a world of enemies.
但是霸王龙却生在一个危机四伏的世界中。
And survival, for this goliath, is never guaranteed.
生存,对于这种巨兽来说,也并非易事。
Herbivores are not dummies.
食草类恐龙可不是傻子。
They'll try to remove the dangerous elements in a preemptive strike.
它们会先发制人地消除潜在的危险因素。
If you're a baby Tyrannosaur, every mega-herbivore in the environment wants to crush you.
如果你是只小霸王龙,周围的每只大型食草恐龙都想将你踩死。
Even the Triceratops with its tiny brain, is aware of the T. Rex's potential menace.
即使是大脑奇小的三角龙也能意识到霸王龙的潜在威胁。
Knowing that one day this tiny T. Rex chick will grow into a menacing monster, easily able to attack and defeat this plant eater.
它知道总有一天这只霸王龙幼崽会成长为可怕的掠食者,能够轻易攻击并击败这只食草恐龙。
But maybe that the worst enemy is a bit closer to home.
但是最可怕的危险也许在巢穴附近。
Probably the greatest danger to a baby T. Rex is another T. Rex, the family from over the hill.
对于一只霸王龙幼崽的最大威胁就是另一只霸王龙,来自山的另一侧。
Because Darwinian calculus tells you, the predator, to eliminate your competition, other predators, whenever you can.
因为达尔文的数据表明,掠食者应尽可能地铲除其他的掠食者。
Male lions defend their cubs against rivals who see their offspring as future competition for food and mates.
雄狮会保护幼崽免受那些把幼崽视作未来的食物与配偶竞争者的伤害。
So it is likely that an intelligent predator like T. Rex would do the same.
所以对于智力发达的霸王龙来说,它们也会这么做。
Compared to prehistoric plant eaters, its cerebrum, the part of the brain associated with strategy, is huge.
与史前食草动物相比,它的大脑中掌管策略的部分体积很大。
So is the cerebellum, which controls muscle function.
小脑也很大,负责控制肌肉的功能。
This is an animal that can plan and execute a devastating attack.
这是一种可以计划并执行一次致命攻击的动物。
It's a behavior hardwired into the brain.
这种行为在其脑中已根深蒂固。
If you're trying to increase your evolutionary advantage, the best thing you can do is get more offspring into the future generation.
如果要增加进化的优势,最佳方式就是让更多幼崽能够存活到下一代。
And one of the best ways you can do that is to take better care of the offspring that you produce.
而保证这样的最佳方式就是尽可能地保护好幼崽。
Laying eggs nearly depletes a female.
产卵已经让雌龙筋疲力竭了。
She needs nourishment to stay strong. And nourishment means meat.
它需要补充营养 保持体力。而营养就意味着肉。
While she searches for her next meal, the male stays behind to guard the nest.
在它出去觅食的时候,雄龙在巢穴边留守看护。
