摘要翻译：
在有人提出地球上的生命可能来自早期文明的播种后，一些作者指出，这种替代方案提供了一个可测试的方面：种子可以提供一个可能在现存生物中找到的标志。特别是，有人认为这种伪影的最佳位置是遗传密码，因为它是细胞中进化最少的部分。然而，正如主流观点所说，这种情况过于推测，无法进行有意义的测试，因为编码/解码遗传密码中的签名是不明确的，所以任何检索尝试都注定是猜测。在这里，我们更新种子-地球假设，并讨论插入签名的动机。然后，我们表明“生物SETI”比传统SETI涉及更弱的假设，并承认一个明确定义的方法框架。在从分子和进化生物学的角度对可能性进行评估后，我们将该方法形式化，并采用SETI的编码/解码应遵循第一性原则和不受常规约束的指导思想，制定了检索策略。应用于规范码，它揭示了联锁系统属性的非平凡精确结构。为了根据最初的假设评估这一结果，我们进行了统计、比较、相互依赖和符号学分析。统计分析表明与代码的进化模型没有因果关系，相互依赖分析排除了过度解释，比较分析表明已知的代码变异缺乏任何精确逻辑结构，这些变异与规范代码的种子后偏离一致。最后，符号学分析表明，所发现的属性不仅与最初的假设一致，而且从SETI的角度来看，它们是完全有意义的，因为它们保持了一些最普遍的文化代码。

英文摘要：
  After it was proposed that life on Earth might descend from seeding by an earlier civilization, some authors noted that this alternative offers a testable aspect: the seeds could be supplied with a signature that might be found in extant organisms. In particular, it was suggested that the optimal location for such an artifact is the genetic code, as the least evolving part of cells. However, as the mainstream view goes, this scenario is too speculative and cannot be meaningfully tested because encoding/decoding a signature within the genetic code is ill-defined, so any retrieval attempt is doomed to guesswork. Here we refresh the seeded-Earth hypothesis and discuss the motivation for inserting a signature. We then show that "biological SETI" involves even weaker assumptions than traditional SETI and admits a well-defined methodological framework. After assessing the possibility in terms of molecular and evolutionary biology, we formalize the approach and, adopting the guideline of SETI that encoding/decoding should follow from first principles and be convention-free, develop a retrieval strategy. Applied to the canonical code, it reveals a nontrivial precision structure of interlocked systematic attributes. To assess this result in view of the initial assumption, we perform statistical, comparison, interdependence, and semiotic analyses. Statistical analysis reveals no causal connection to evolutionary models of the code, interdependence analysis precludes overinterpretation, and comparison analysis shows that known code variations lack any precision-logic structures, in agreement with these variations being post-seeding deviations from the canonical code. Finally, semiotic analysis shows that not only the found attributes are consistent with the initial assumption, but that they make perfect sense from SETI perspective, as they maintain some of the most universal codes of culture.
