動物とそれに関連する微生物群の関係は、宿主の進化史と環境に依存しています。ほとんどの研究は、これらの要因のうちの1つに焦点を当てることが多く、関連する細菌の群落構成をどのように特定するかを考慮することはほとんどありません。進化史、共有環境、およびこれらの要因間の相互作用が群落構成をどのように駆動するかをテストする「自然実験」は、ペアの種対を比較することです。既知の進化史と、カリブ海と太平洋の海洋学的特性の違いから、パナマ地峡によって隔てられたキバナユビヒトデは、このような比較に適しています。
キバナユビヒトデとニソゲヒトデのペア種対の卵に関連する微生物群を比較することで、各ペアの種が系統共生と一致するパターンで異なる細菌群と関連していることがわかりました。宿主の進化史と環境の相互作用が、これらの群落の違いを最もよく説明しています。
さらに、海洋間では特定の微生物類群に大きな違いがあるが、海洋内ではそれほど違いがないことがわかりました。2種のカリブ海のキバナユビヒトデの微生物群は、主に光合成酸素発生細菌に支配されています。
以上のことから、本論文で提供されたデータは、双子種に関連する微生物群が、約280万年の隔離期間中に分化したこれらの分類群の別の特徴であるという仮説を支持しています。
