赞~~

移民星球的生态改造我也在读相关资料。卡尔萨根有篇论文。

看到 @SpaceXploration 微博提到了 C. Smith 在 FISO 的一个关于安全的星际航行需要的人数的 lecture,然后我去把他的论文找出来了:

Estimation of a genetically viable population for multigenerational interstellar voyaging: Review and data for project HyperionPDF

看了下挺有意思的。他们考虑了很多因素,主要是生物(基因)上的因素,包括:

  1. 突变
  2. 选择
  3. 漂变
  4. 迁移

还有个非常重要的,就是有个 Founder effect(一群人离开原来的群体单独繁衍之后会跟原来有很大的区别)。

他们考虑了飞船上 5 代繁殖的星际移民。考虑不同的人数和成分。例如,其中一种如下男性成分表(女性相同)

人群 配对 未配对
未成年 0 6800
成年人 6700 5000
老年人 1000 500

这样总的起始人数为 40,000 人。有效人数只有 23,400 人。

结论是虽然起始人数大于 30,000 ,有效人数大于 10,000 就可以在飞船上比较健康的活 5 代,比较保险的是总人数大于 40000 人。


评论:这篇文章写得很差劲,说是 review 不像 review,但是又没用细节,总之不好。


这里面好像有个很重要的概念叫做: Extinction vortex

发现我最近研究的生物方面的内容似乎跟星际移民的不太相关,主要是太实际了。

但是我似乎记得很多小说里有某些生物技术,可以研究参考一下。
