人造生命?

2010/5/22

这周是科学史上突破性的一周。你有没有注意到这条新闻:克雷格博士(Craig Venter)与他的团队已经创造了首例人造生命!他们表示试验就是先掏空一个细菌细胞的基因编码。然后,利用计算机创造新的基因编码,并且注入此细菌细胞,使得它“起死回生”。这是首例人工合成细胞,可以自我繁殖。设计这个细胞结构的就是计算机。

请注意,我们迄今为止还不知道这条新闻的真假。相信随着时间的流逝,真想会大白。

不过,我们在这里假设这不是骗局,而是真实发生的事情。那么从一位基督徒的角度来看,这到底意味着什么。

首先,这是否证明了神没有创造生命?不是。这个实验恰恰证明了哪怕创造一个单细胞,我们都需要多年的研究。生命的创造极为复杂,需要大量的研究与计划。而关于造物的争论仍旧存在:谁创造了我们?有些人说是外星人。那么,谁创造了外星人?

其次,虽然这项成就有利有弊(详见下文)但关键在于DNA编码本身。举个例子,空气中历来含有氢气,但直到几千年后人们才明白其成分并发明了氢弹。同样,自地球有生命以来,DNA就一直存在。但知道近年我们才开始研究DNA背后的故事。就像学生研究电脑并把它拆分,科学家在细胞研究方面也如出一辙。科学家复制了细胞。但真正的英雄不是复制DNA编码的人,还是创造DNA编码的。

最后,此次试验据说是把人工合成基因组放入一个被掏空了遗传物质的细胞。然后细胞分裂增生。我们在这一领域仍需更深入的研究。打个比方。死的植物种子可以在水分与阳光的帮助下再次发芽。众所周知的一个例子就是考古学家发现了两千多年前与埃及法老同埋的种子。虽然年代久远,但当种子再次培育的时候,仍旧可以发芽成长。

人造生命之利弊

新闻报道宣称此次人造生命的成就会带来无尽好处。比如,我们可以设计一种细菌,专门吸收大气层的过量二氧化碳。虽然这个点子听上去不错,但我们不能忽视人造生命可能会带来的危险。生化武器会更加致命。万一有人研究出一种细菌,绝杀一个种族怎么办?我们所拥有的生态系统极为复杂。突然之间出现一个新的生命体,可以不断自我复制,无人能预料这会对自然界会产生怎样的影响。

Man Creates Life?

2010/5/22

This has been a momentous week. If you have not yet heard the news: Dr. Craig Venter and his team have created the first man-made life!
What they say they did was empty a bacteria cell of its own genetic code, wrote a new genetic code using a computer, inserted the new code into the bacteria shell, and it lives. This first man-made species is now self-replicating. Its parent is said to be a computer.

Please know this could be a hoax. Time will tell.

But, assuming it is true, let’s analyze what has happened from a Christian point of view.

Firstly, does this prove that life exists without God? No. What it shows is that decades of research and intelligence were required to produce this life-form. Life requires careful planning and intelligence. This question still remains: Who was the intelligence that created us? Some answer, “aliens,” but then, who made the aliens?

Secondly, although this is an amazing discovery with positive and negative implications (see below) what it has shown is the power locked within DNA code. For thousands of years people lived with hydrogen before unlocking the power of the H-bomb. Likewise, DNA has existed as long as life on earth, and we have only recently begun to understand it. Just as a student studies and takes apart a computer in order to build his own, so scientists have now done the same with the cell; they have copied the orginal. The hero here is not the one who copied the code, but rather the One who made the code.

Thirdly, it is said that non-living DNA was inserted into a dead bacteria cell. The cell then came to life. This requires further study. Take for example plant seeds. They can appear dead until one puts them in water and sunlight. In one famous example seeds that were buried with ancient Egyptian pharos over 2,000 years ago were discovered. Although very old, when planted 2,000 years later, these seeds grew and produced plants.

Negative and Positive Implications
Newspaper articles have been saying that this discovery’s potential for good is incredible. One could design bacteria, for example, that could absorb excess CO2 in the atmosphere. That sounds good, but there are terrible dangers too. Imagine the potential for biological weapons. Could someone design a germ to kill only a certain ethnic group? Also, the ecosystem we live in is extremely complex. No one knows what would happen if a new self-replicating life-form was released into nature.

As said above, this may be a hoax, but should it not be, I believe the world has changed from this week.
