我国科研人员在一种名为乌毛蕨的蕨类植物体内，不仅发现大量富集的稀土元素，还首次观测到这 些稀土元素在植物组织细胞间"自我组装"，形成了一种名为"镧独居石"的矿物。 这是科学家首次在天然植物中发现稀土元素的生物成矿现象，为未来稀土资源的可持续利用提供了 新路径。相关成果于11月5日在线发表于国际学术期刊《环境科学与技术》。 稀土被誉为"工业维生素"，是人工智能、新能源、国防等重点领域不可或缺的核心战略资源，但传 统稀土矿物开采伴随着生态环境破坏。近年来，中国科学院广州地球化学研究所朱建喜研究员团队致力 于寻找更清洁、更可持续的稀土获取方式。 此前，科学界已发现乌毛蕨等一批特殊的稀土"超积累植物"，即对稀土元素具有超强富集能力。它 们仿佛土壤中的"稀土吸尘器"，能高效吸收并浓缩分散在环境中的稀土元素。 在该研究中，科学家观测到，在乌毛蕨叶片的维管束和表皮组织中，从土壤中吸收的稀土元素会以 纳米颗粒形式沉淀，并进一步结晶成一种名叫"镧独居石"的矿物。进一步研究发现，该过程实际上是一 种植物的自我保护机制，就像是植物在体内"打包封存"有毒物质，把可能伤害细胞的稀土离子，稳稳锁 进矿物结构中，实现稀土的钝化和自然"解毒 ...

Core Concept - The article discusses the concept of the "triple helix" proposed by R.C. Lewontin, emphasizing the interaction and influence among genes, organisms, and the environment [1][8]. Group 1: Genetic Determinism Debate - Lewontin criticizes genetic determinism, arguing that the human genome differs by less than 0.1%, yet it is misused to explain social inequalities such as wealth, intelligence, and crime [5][6]. - He asserts that the environment is not merely a container but is actively shaped by organisms, which select and modify their surroundings [5][8]. - The completion of the Human Genome Project, according to Lewontin, will not achieve its intended purpose of identifying disease-causing genes through DNA comparison [5][6]. Group 2: Responses from Richard Dawkins - Richard Dawkins responds to Lewontin's critiques, clarifying that he never claimed genes determine everything, but rather that genetic differences can explain phenotypic variations [6]. - Dawkins emphasizes the directionality of evolution, countering Lewontin's and Gould's views on randomness in evolution by citing examples like the speed of cheetahs [6]. - He argues that moral responsibility should not be outsourced to science, maintaining a distinction between scientific conclusions and their political implications [6]. Group 3: Impact on Biological Sciences - The debate between Lewontin and Dawkins has had a lasting impact on the field of biology, with new perspectives emerging, such as those presented by behavior geneticist Kathryn Harden in her book "The Gene Lottery" [7]. - Harden attempts to find a middle ground, acknowledging the significant role of genes while also recognizing the influence of luck and the potential for social policies to mitigate genetic impacts [7]. - However, Lewontin remains critical of this middle ground, insisting that the interactions among genes, environment, and randomness are too complex to disentangle [7][8]. Group 4: Science as a Social Institution - Lewontin argues that science is not an isolated pursuit of truth but a social institution influenced by political and economic factors [10][11]. - The direction of scientific research is often driven by societal needs and interests, rather than purely by the quest for knowledge [10][12]. - Cultural and ideological contexts shape scientific inquiry, affecting research focus and methodologies across different societies [11][12]. Group 5: Historical Context and Future Implications - Historical examples illustrate the close relationship between biology and political ideologies, such as the use of Darwinian theory in imperialism and eugenics [12]. - The ongoing developments in biological sciences, particularly in the context of the COVID-19 pandemic, raise questions about the political implications of scientific advancements [12].
