The comparative analysis of scientific heritage of Richard Goldschmidt and Julian Huxley shows convincingly the resemblance of these two scientists' views over the core problems of evolutionary theory, genetics and development biology. They both contributed to developing a triad "genetics--development--evolution". The problem of a relative growth of animals was the central point in both Goldschmidt's and Huxley's works. Huxley developed a formula of the allometric growth (law of constant differential growth) while Goldschmidt was the first to draw up the broad interpretation of the consequences of that phenomenon. Both scientists belonged to initiators of development genetics and used the "non-morganian" genetics in their efforts of solving problems of macroevolution. Goldschmidt tended toward an idea of an important role of macromutation in the process of macroevolution, though Huxley adhered to more moderate views. But at the same time the concept of preadaptive mutations proposed by Huxley was close to Goldschmidt's idea of macromutants. It is shown that both scientists analyzed profoundly the changes in early stages of embryogenesis in respect to macroevolution. It is not likely to be reasonable to oppose firmly Goldschmidt's saltationism to the evolutionary synthesis of Huxley. They developed the larger biological problems in a similar way, and undoubtedly their works in the field helped to enrich the development of the views over genetics and evolution. The open-minded analysis of Goldschmidt's and Huxley's concepts leads to creating modern and up-to-date views over the theory of evolution where seemingly incompatible things go together rather well and supplement each other. Evo-Devo rediscovered Goldshmidt's Biology and Huxley's Synthesis.
对理查德·戈德施密特和朱利安·赫胥黎科学遗产的比较分析令人信服地表明,这两位科学家在进化理论、遗传学和发育生物学的核心问题上观点相似。他们都为发展“遗传学——发育——进化”三元组做出了贡献。动物相对生长的问题是戈德施密特和赫胥黎著作的核心要点。赫胥黎提出了异速生长公式(恒定差异生长定律),而戈德施密特则率先对该现象的后果进行了广泛解读。两位科学家都是发育遗传学的开创者,并且在解决宏观进化问题时都运用了“非摩尔根式”遗传学。戈德施密特倾向于认为大突变在宏观进化过程中具有重要作用,尽管赫胥黎秉持更为温和的观点。但与此同时,赫胥黎提出的预适应突变概念与戈德施密特的大突变体概念相近。研究表明,两位科学家都深刻分析了胚胎发育早期阶段相对于宏观进化的变化。将戈德施密特的骤变论与赫胥黎的进化综合理论坚决对立起来不太合理。他们以相似的方式探讨了更大的生物学问题,毫无疑问,他们在该领域的工作有助于丰富遗传学和进化观点的发展。对戈德施密特和赫胥黎概念的开放分析有助于形成关于进化理论的现代且最新的观点,在这个观点中,看似不相容的事物能够很好地相互融合并相互补充。进化发育生物学重新发现了戈德施密特的生物学和赫胥黎的综合理论。
