人类比你想象中高得多

The Tallest Lifeforms Of All Time

[解说员]如果你长高一倍
– [Narrator] If you doubled in size,
你的体重则会增长八倍
your weight would be eight times greater.
这就是长高带来的烦恼
That’s the trouble with growing tall.
我们的生长受制于地球引力
Gravity’s pull is keeping us all down,
但地球上仍有少数巨型生物
but there are a few earthly giants
与地球引力抗争并取得了胜利
that have fought gravity and won.
[舒缓的器乐]
(gentle instrumental music)
长高的秘诀取决于你如何运用自己的能量
The key to growing tall ishow you use your energy.
这就是为什么树比地球上任何一种动物都高的原因
That’s why the tallest treesoutrank any animal on Earth,
因为树把其所有的能量都花在一件事上
because trees spend alltheir energy on one thing;
即 要比它们周围植物都长得高
growing taller thantheir fellow neighbors.
同时有两种树是所有树木中长得最高的
And there are two treesthat are the best growers
巨型红杉和花楸
of them all: giant redwoodsand mountain ashes.
红杉被誉为地球上最高的生命体
Redwoods are renowned as thetallest lifeforms on Earth,
但一些专家认为如果人们停止砍伐花楸
but some experts think thatmountain ashes could grow
那么花楸将会比红杉长得更高
even taller if humans wouldstop cutting them down.
事实上 世界上最高的花楸
In fact, the tallest mountain ash was just
仅仅只比最高的红杉矮了一米
one meter shorter thanthe tallest redwood.
与植物不同 动物把能量用于各个方面
Unlike plants, animals spendenergy on all sorts of tasks,
比如进食 行走以及保暖等
like eating, walking, and staying warm,
所以动物没法长树木那么高
so they can’t grow as tall.
但这也不能代表动物就矮
But it doesn’t mean they’re small, either.
如果你从地面开始测量这头非洲象到其肩部
If you measured this African elephant from shoulder to ground,
那么实际上它比一头长颈鹿都高
it would actually be taller than a giraffe,
但由于长颈鹿长而有力的脖子
but thanks to their long, strong necks,
它们是地球上现存的最高动物
giraffes are the tallest animals alive.
如果我们纵观地球历史上的动物
And if we look at animalsthroughout Earth’s history,
所有动物身高在恐龙面前都将黯然失色
dinosaurs eclipsed them all.
这些高大的蜥脚类恐龙是所有恐龙中最高的
These towering sauropods werethe biggest of the bunch.
事实上 前十位有史以来最高的动物
In fact, the top ten lists of tallest
都是恐龙
animals in history? All dinosaurs.
但如果我们把最长的生命体也包括进来 结果也一样吗?
But what if we looked atthe longest lifeforms, too?
如果你让世界上最长的咸水鳄用鼻子保持平衡立起
If you balance the longestsaltwater crocodile on its nose,
那么它将和长颈鹿一样高
it would tie the giraffe.
并且如果把长颈鹿的脚排除在外 咸水鳄则更长
And if we ignore legs it gets even better. Tip-to-tail,
绿水蚺从头部到尾巴计算
the greenanaconda nearly doubles
其长度几乎是最高的长颈鹿的两倍长
the height of the tallest giraffe.
但这些陆地生物与深海生物相比就小巫见大巫了
But these land-dwellers havenothing on animals of the deep.
因为水的浮力 海洋生物几乎可以无视重力
Supported by water, sea lifecan practically ignore gravity,
这意味着它们能长得更大
which means they can grow much larger.
就拿蓝鲸举例吧
Take the blue whale, for example.
它是有史以来体型最大的动物
It’s the most massive animal of all time.
举个例子 百老汇舞台剧
For example, the entire cast of Broadway’s
《狮子王》中的全部演员能在它的舌头上演出
The Lion King can fit on its tongue.
但蓝鲸要小心
But it should be careful not to get tangled up
不要被狮鬃水母的触须缠住
in the tentacles of a lion’s mane jellyfish,
与狮鬃水母相比 巨型乌贼显得格外小型
which makes the giant squidlook small by comparison. Now,
目前 现存的最大鱼类是鲸鲨
the biggest fishalive is the whale shark,
但如果我们往前看还有更大的鱼类
and if we look into thepast things get even bigger.
所以人类高度处于生物界中的哪个位置呢?
So where do humans fit into all this?
事实上 人类高度接近生物界的顶端
Somewhere near the top, actually.
人类比地球上87.6%的哺乳动物都高
Humans are bigger than87.6% of mammals on Earth
并且荷兰人的平均身高是人类中最高的
and the average Dutchmanis the tallest of them all.
所以我们没有理由再觉得自己矮小了
So there’s no reason toever feel small again,
由其是如果你来自荷兰的话
especially if you’re from the Netherlands.
[舒缓的器乐]
(gentle instrumental music)
一个有趣的事实 史上最长的生命体
Fun fact, the longestlife-form of all time
并不是植物或者动物
isn’t a plant or animal at all.
蜜环菌才是史上最长的生命体
It’s a honey fungus andthe biggest one goes on
而最长的蜜环菌生长在俄勒冈州森林地下 长度约3.8千米
for 3.8 kilometers underneatha forest in Oregon.
