Beyond Biotechnology: The Barren Promise of Genetic Engineering
武漢肺炎/2019冠狀病毒病 (COVID-19)初起時,神奇國度拒絕世衛前往武漢調查。當時竟然有人説:因為中國人的基因特別,怎可以給人去檢驗? 話說2001 年,人類基因組計劃宣布已成功繪製出人類 DNA 的全部遺傳內容。科學家、政治家、神學家和權威人士猜測接下來會發生什麼,從國家控制的優生學的噩夢場景到工程抗病新生兒的希望,無所不包。與圍繞幹細胞研究的爭論一樣,基因工程看似無窮無盡的可能性將在可預見的未來繼續影響公眾輿論和政策。 ‘’Beyond Biotechnology: The Barren Promise of Genetic Engineering‘’區分了這項技術的炒作和現實,並解釋了科學與自然之間微妙而微妙的關係。作者 Craig Holdrege 和 Steve Talbott 評估了基因科學的現狀並研究了它的潛在應用,特別是在農業和醫學領域,以及可能存在的危險。 作者展示了流行的遺傳學觀點如何不包括對基因在生物體中實際協同工作方式的理解。對基因的簡單化和簡化主義觀點會導致不切實際的期望,並最終對基因工程實際提供的結果感到失望。作者探索了遺傳學的新發展,從發現細菌中的“非達爾文”適應性突變到表明生物體不僅僅是遺傳驅動機制的集合的證據。 在研究這些問題的同時,作者還回答了涉及基因與人類生物學本質相互作用的重要問題:DNA“管理”有機體是否比有機體管理其 DNA 更重要?基因工程產品是否應該貼上這樣的標籤?基因工程師的方法是否類似於數百年來的畜牧業實踐? Beyond Biotechnology 是為非專業讀者編寫的,它是對基因工程及其潛在應用的複雜問題的易懂的介紹。在自然與實驗室之間未開發的空間中,一門新的科學正在等待出現。只要我們的文化與所有生命賴以生存的植物和動物疏遠,基於技術的社會和環境解決方案將仍然脆弱並面臨逆轉的風險。
