程度副詞

that we're the perfectly evolved species,

and then I get migraines and puke for seven hours.

然後，我得到偏頭痛和 嘔吐了七個小時。

- Every time I explore a new city, I sprain my ankle.

- 每當我探索一個新的城市，我都會扭傷腳踝。

- 格雷格的媽媽給了他一根手杖。

So today we're going to go on a journey of biology

那麼今天我們就來進行一次生物之旅吧

starting with your terribly designed feet.

- Apart from being sexually attractive to some people,

- 除了對某些人有性吸引力外。

was Gaston's foot in "Beauty and the Beast."

在 "美女與野獸 "中是加斯頓的腳。

- (laughs) Our feet are an evolutionary mess.

- (笑)我們的腳在進化過程中是一團糟。

Early hominids would stay safe from predators

早期的類人猿會遠離掠食者，保持安全。

were initially designed to grasp or grab branches.

最初的設計是為了抓住或抓住樹枝。

Please don't put this on WikiFeet, you freaks.

請不要把這個放在WikiFeet上，你這個怪胎。

And the way our feet would grip the tree branch

was with numerous complex bones in the feet,

much like the apes and chimps climbing in trees today.

就像今天爬在樹上的猿猴和黑猩猩一樣。

This is why you currently have the absurd amount

這就是為什麼你目前有荒唐的數量。

That is way too many for just walking around.

這也太多了吧，光是走走看看就夠了。

So the perfectly evolved human needs the ostrich foot.

所以完美進化的人類需要鴕鳥腳。

Other than humans, birds are the only other

Human started walking upright 5 million years ago,

人類在500萬年前開始直立行走。

whereas birds have been running around on two feet

you see that birds evolved hundreds of millions of years ago

你看，鳥類是在幾億年前進化而來的。

Compared to us, Eutherian mammals on the right over here,

和我們相比，右邊的尤瑟派哺乳動物在這邊。

who on the timeline of evolution of life on Earth

誰在地球生命進化的時間軸上？

pretty much climbed out of trees like yesterday.

幾乎從樹上爬出來，就像昨天一樣。

So it's not surprising that a bird's ancient bipedal design

所以，鳥類古老的雙足設計也就不足為奇了。

would actually help our current bipedal bodies.

其實會對我們現在的雙足身體有所幫助。

These two toes stabilize the foot in running mode,

這兩個腳趾在跑步模式下可以穩定腳步。

We have found broken ankles in human fossils

我們已經在人類化石中發現了斷腳踝

So we've been breaking our ankles for millions of years.

所以我們的腳踝已經斷了幾百萬年了。

I don't feel so bad about my ankles anymore.

我覺得我的腳踝不再那麼糟糕了。

Our ankles have intervening ligaments and seven bones,

我們的腳踝有中間的韌帶和七根骨頭。

With these ankles, we'd optimize our upright balance,

有了這些腳踝，我們就能優化我們的直立平衡。

locomotion, and deal a lot better with crashes.

運動，處理撞車問題也會好很多。

This is why ostrich legs have been used as models

這就是為什麼鴕鳥腿被用作模型的原因。

walks with the speed somewhere between human and ostrich.

走路的速度介於人類和鴕鳥之間。

and is a telltale sign of old age, knees.

並是老了的一個明顯標誌，膝蓋。

- Our knees are a particular type of mess.

- 我們的膝蓋是一種特殊的混亂。

that we stopped evolving biologically 10,000 years ago

我們在一萬年前就停止了生物演化

And they argue that from that point forward,

But then, other evolutionary biologists think

have actually allowed for adaptive evolution,

And that, folks, is an example of evolutionary biologists

各位，這就是進化生物學家的一個例子

battling it out with separate contradicting theories.

This actually happens a lot in this field of study

這種情況其實在這個研究領域經常發生

because we're trying to piece together information

about our human history over thousands of years.

不管是哪種方式，有一件事我們是肯定的

is that we are not running from predators,

and when it comes to eating food, we're not hunting it.

而當談到吃的食物， 我們不是狩獵它。

I press a button on my measly little electronic device

我在我那小小的電子設備上按下一個按鈕。

I know for a fact, you probably do this too,

And for this reason, our knees need to change.

為此，我們的膝蓋也需要改變。

Anthropologist Matt Cartmill explains that,

人類學家馬特-卡特米爾解釋說。

"Evolution doesn't act to yield perfection,

"進化的作用並不是為了產生完美。
