如果未来人类继续进化?

What If Our Bodies Kept Evolving?

What will humans look like in 10,000 years?
一万年后人类看起来是什么样?
What about in 1 million years?
一百万年后又如何?
Will we look like this guy?
我们会变成这样吗?
Probably not.
可能不会
But we’ll definitely look different than we do now.
但我们绝对和现在不一样
What parts of our body would evolve?
我们身体哪部分会进化?
How long would evolving our bodies take?
进化我们的身体需要多长时间?
Who would win the survival of the fittest?
谁会赢得适者生存?
This is WHAT IF.
这里是《自然无常》
And here’s what would happen if our bodies kept evolving.
让我们看看如果我们的身体持续进化都会发生什么
It took roughly 6 million years.
人类花了差不多六百万年
For humans to become what we are today.
才成为现在这样
And modern humans have only been around for about 12,000 of those years.
而现代人类仅存在了大概一万两千年
Even in that short period of time,
即使在那样短暂的时间里
humans have evolved slightly.
人类依然进化了一点
We’ve become about 10 cm (4 in.) taller.
我们长高了大概10cm(4英寸)
And now we can eat dairy foods after childhood.
现在我们过了幼儿期也能吃乳制品
So if those things can happen in 12,000 years,
所以如果这些事可以发生在一万两千年里
where might we be hundreds of thousands of years into the future?
那在未来百万年后 我们身上又会发生什么呢?
First, we should probably figure out exactly what evolution is.
首先我们要弄清楚进化到底是什么
Evolution is all about changes in the genetic makeup
进化是指种族随时间而产生的
that happen to a species over time.
基因构成方面的变化
Species with more advantageous traits will tend to have more offspring.
拥有更多优势特征的种族趋向于有更多后代
So those genetic traits will tend to carry on to later generations.
于是那些基因特征会倾向于遗传到下一代
For example, giraffes with longer necks who can reach more food
比如 脖子长的长颈鹿能获取更多食物
will be able to survive better than giraffes with short necks.
就比脖子短的长颈鹿更容易存活
And they’ll be able to have more babies,
生下更多长颈鹿宝宝
who will likely have longer necks, just like their parents.
这些宝宝就很可能有和父母类似的长脖子
And as time goes on, the short-necked giraffes will die out,
随着时间的持续 短脖子的长颈鹿就会灭绝
and the long-necked giraffes are the only ones left.
长脖子的长颈鹿变成种族中仅剩的种类
That’s why all our giraffes have long necks today.
那就是现在的长颈鹿都是长脖子的原因
So how does this apply to humans exactly?
所以进化到底怎么发生在人类身上的呢?
Well, evolution, in this sense, is actually very hard to predict.
嗯 这种情况下 实际上进化很难预测
In the world we live in, we don’t need to worry about survival of the fittest.
在我们生存的世界里不用考虑适者生存的问题
Technology has effectively canceled a lot of that.
科技已有效解决了很多生存问题
You no longer need to worry about being the fastest or the strongest.
你不再需要担心怎么成为最快的或者最壮的
This isn’t 100,000 years ago, when you had to fight for your food.
这不是十万年前 你必须战斗获取食物
Things like houses to live in, and clean running water, make surviving so much easier.
像住的房子和干净的自来水等 使得生存如此简单
You never think to yourself, “how am I going to survive today?”
你永远不用去思考“今天我该如何生存?”
But that’s something our ancestors had to worry about constantly.
但那却是我们的祖先必须不断忧思的问题
It’s not guaranteed that 1 million years from now,
我们并不能保证 现在起百万年后
humans will be stronger, faster, and bigger than ever before.
人类会比之前更强 更快 更大
After all, having children today is generally decided by culture and personal choice,
毕竟现在生宝宝一般都是取决于文化和个人选择
rather than the need for our species to survive.
而不是我们种族生存的需要
Our future will be decided by the traits of people who have children,
我们的未来会取决于那些有孩子的人的特征
and how many children they have.
和他们孩子的数量
If people who are naturally overweight and have health problems
如果下个一百万年 只有那些天生身体超重
are the only ones having kids over the next million years,
有健康问题的人才有孩子
then that’s how the human race will end up.
那么人类种族就会成为这样
But we might not need to worry about any of these natural occurrences.
但我们可能不必担心这些自然发生的问题
Instead, we could become completely fused with technology before any of this happens.
反而我们可能在这些问题发生之前完全与科技融合
Cybernetic arms, brain chips, and laser eyes could all become possibilities.
自动化的手臂 脑芯片 激光眼 都会成为可能
Not only that, but we also might be able to alter a baby’s genes before they’re born,
不仅如此 我们还可能在婴儿出生前改变它的基因
completely getting rid of evolution altogether.
完全摆脱进化过程
This would allow us to get rid of diseases, and any other genetic traits that might harm us.
从而使我们摆脱疾病和其他可能对我们有害的基因特征
But if we didn’t have this luxury, and we had to evolve the old-fashioned way,
但如果我们没有这个幸运而不得不按照以前的方式进化
there’s a few things that might happen.
有些事可能就会发生
we just need to look at how modern humans have evolved in the past 12,000 years.
我们只需要看看现代人类在过去一万两千年里怎么进化的
We know we’ve been getting taller, most likely due to nutrition,
我们知道很大程度因为营养充足 我们在变高
and that our brains have been getting smaller.
而我们的大脑也在变小
But don’t worry, we haven’t be getting dumber.
但别担心 我们没变笨
our brains are actually becoming more efficient.
事实上大脑运行更高效了
So, in a million years, we might be incredibly tall humans with tiny heads.
所以 在这一百万年中 我们可能变成头小的高个子
Does that remind you of anything?
这有没有让你想起什么?
At the end of the day, human evolution is incredibly difficult to predict.
最后说一句 人类进化方向预测极端困难
That’s because, evolution is primarily based on our environment,
因为进化主要基于我们的生态环境
and who knows what might happen to the Earth in the next million years?
谁又知道地球在这一百万年会发生什么呢?
We might need to evolve to survive fires, as the planet will become so incredibly hot.
当地球温度酷热无比时 我们可能要进化得能在火中生存
I so hope I’m not around for that.
只希望我不要经历那些
Or, in the next million years, we might live on other planets, like Mars.
或者一百万年后 我们生活在其它星球 比如火星
Humans would evolve to look completely different there,
在那儿人类进化得看起来完全不一样
as they’d be living in entirely different conditions than here on Earth.
比起地球 那里的生存条件完全不同
Wondering what living on the red planet would be like?
好奇红色星球上的生活会是什么样的吗?
Well, that’s a story for another WHAT IF.
好了 那就是另一个《自然无常》的故事了
