Science：人的确就是人和微生物的超级共生体？
- ①Moeller等人的研究清晰地表明，在过去1500万年间，肠道细菌与人科动物协同种化；
- ②研究者比较了人类、黑猩猩、倭黑猩猩、大猩猩粪便中拟杆菌科和双歧杆菌科特定株细菌的gyrB基因；
- ③除了灵长类动物间非常稀有的共生转移，比较主要细菌谱系的gyrB基因的种系发生，揭示它们与类人猿种系发生基本相符；
- ④肠道细菌并不是简单地从环境获取，而是在数百万年间与人科动物共进化，并塑造我们的免疫系统和发育。

Abstract:收起
Mutualistic symbiotic relationships are those in which both species benefit; for example, the vivid colors of coral reefs come from symbiotic algae that provide their living coral hosts with nutrients and oxygen through photosynthesis in exchange for protection. A similar mutualistic relationship exists between gut-dwelling bacteria and their animal hosts (1). It remains unclear, however, to what degree symbiosis has shaped host-microbial interactions and coevolution. On page 380 of this issue, Moeller et al. show that gut bacterial strains cospeciated with hominids (apes and humans) over the past 15 million years (2). These findings set the stage for exploring the evolutionary processes that underlie the symbiotic relationship between hominids and their gut-dwelling microbes.
