生命从何而来？第一个真正意义上的生命体究竟应当具备什么条件？从非生命物质到能够自主维持、复制和繁衍的细胞之间，是否存在尚未跨越的科学鸿沟？《进化的边界 II：PULO 原始普世生命体起源》围绕生命起源这一科学史上最深刻而又最具争议的问题展开讨论。作者提出'原始普世生命体'（Primitive Universal Living Organism，简称 PULO）这一概念，用以描述可能最早出现、具备现代生命细胞基本特征和自主生命活动能力的生命体，并以此重新审视有关生命起源的主要科学假说。全书从构成生命的蛋白质、核酸、脂质和糖类等基本有机物质出发，逐步进入细胞结构、原核生物及早期生命形式的讨论，并系统考察病毒世界、蛋白质世界、RNA 世界、脂质世界以及非生生成等生命起源假说。在此基础上，作者重点分析从简单有机分子、囊泡和前生命体系走向具有代谢、膜结构、信息传递、自我复制和繁殖能力的 PULO 所必须面对的一系列关键问题。本书并非否定生命起源领域的科学探索，而是强调科学研究必须严格区分假说、推理、实验结果与已经得到验证的事实。作者通过对现有理论和研究路径的梳理与质疑，邀请读者重新思考一个看似简单却至今没有最终答案的问题：生命究竟是怎样迈出第一步的？这是一部融合分子生物学、细胞生物学、生命起源研究与科学哲学思考的探索性著作，也是一场关于生命边界、科学证据以及人类认知极限的讨论。

  • Exploring Genome’s Junkyard
    Subir Ranjan Kundu
    Exploring Genome’s Junkyard: In the Labyrinth of Evolution narrates the progress of biological evolution, beginning with the conceptual introspection of gene and continuing with the contemporary understanding of the structural and function aspects of the human genome. Recent advances in human genome research have led scientists to the term 'biological dark matter,' which refers...
  • European Hair, Eye, and Skin Color
    Peter Frost
    Europeans, especially those from northern and eastern Europe, are unique in having diverse hair and eye colors and a skin almost as pale as an albino’s. Those colors are not only brighter than the original black and brown but also 'purer'-they lie within thin slices of the visible spectrum. Overall, that color scheme is more developed in women, who naturally have a higher incid...

    Mitochondrial Eve and Y-Chromosomal Adam discusses theoretical ideas, interpretations, and paleontological evidence to narrate the origin and evolutionary story of Sapiens through the transitional stages of archaic human species involved in the evolutionary pilgrimage, from the great apes and to modern humans. Author Subir Ranjan Kundu investigates the DNA footprints of primate...
  • When Evolution Stops
    Armando Simon
    Evolution is a fact. The evidence for it is simply overwhelming. However, the original mechanism that generates the evolutionary process, as first put forth simultaneously by Charles Darwin and Alfred R. Wallace and which became known as Natural Selection, has now been seen to be too simplistic by some scientists aside from the hard-core neo-Darwinists who insist that nothing w...

  • THE EMPTY ROOM
    Sean Pan
    Artificial intelligence now writes, speaks, and performs with a fluency that feels uncannily human. Answers sound confident. Explanations feel coherent. Outputs arrive faster than we can question them. And with that fluency comes a quiet assumption: that something like understanding must exist on the other side of the interface.The Empty Room examines why that assumption is so ...
  • 进化的边界
    Sean Pan
    世界上如此之多的生物，各有奇妙的表观形态，它们之间有什么联系吗？自古以来，人们对生命总是充满了好奇和疑问，各种幻想、迷思、假说在哲学、科学、宗教、民间文化等各个领域层出不穷，充分体现了人类丰富的想象力和智慧。达尔文的《物种起源》提出了物竞天择的自然选择假说，用'微小有益变异的缓慢积累'作为性状特征进化的机制解释变异的生物如何在进化中胜出。作者认为'微小有益变异的缓慢积累'的机制是建立在地质渐变论和习得性遗传并且性状特征无限可塑的假设上，这些已经被现代地质学和现代生物学否定，因此达尔文进化论在现代科学中不再成立。达尔文在书中的例证和推理也不能支持超过物种类型的变异，并多处犯了'过度引伸'的错误。作者认为应该根据事实定义进化的边界，特别是作为科普和基础教育的内容，而对未知边界的研究应该存开放的心态。　本评论根据生命科学的原理讨论达尔文的《物种起源》。本书...
