盲眼手錶匠五

　　到底死物可否爆出生命？我的理科知識只有中七程度，實在追不上現時生物科學的發展，唯有聽專家言。以下一段文字是從 《Science and Creationism- A view from the National Academy of Science》裡看到的：

　　Experiments conducted to resemble conditions on primitive Earth have resulted in the production of some of the chemical components of proteins, DNA and RNA. …Scientists have concluded that the “building blocks of life” could have been available early in Earth history…The question is no longer whether life could have originated by chemical processes involving nonbiological components. The question instead has become which of many pathways might have been followed to produce the first cells…

　　這真出乎我意料之外。原來科學家對這個問題已有共識？但我知道，只要我到大學圖書館關於進化論的一欄走一轉，就會找到很多反對進化論的書籍，而它們所說的正好與上面的引文相反：純粹的chance不可能觸發生命由死物中開展。其所引用的原因,一般會近似下段的內容：

　　The biochemical basis of complex life could not have developed through gradual evolutionary change because too many dependent variables would have had to have been altered simultaneously. [引自《Darwin's Black Box》一書的網上介紹]

　　換言之，仍然是complex design與chance的對陣！

　　來到這個地步，好像很一籌莫展，因為對於生物科技的知識，我只有幼兒園水平，而一個幼兒園生是沒資格對研究院的深邃理論作出品評的……

　　可以說的是，關於生命之源的問題，涉及了最新的科學發展，也涉及人們對整個宇宙之存在理由的基本信念。科學的部分實在無能為力，那麼不如轉個角度，以理性來驗視一下一些基本信念罷。[之五]
