Biotic history has accelerated under anoxic environments - Paradox of Foraminifera evolution can solve through field observation, laboratory culture and genomic analyses.

我们推测，海洋原生生物的进化可能是由活跃的微生物共生。与微生物的共生关系适合在危机期间生存，当缺氧环境在海洋中占主导地位。对于真核单细胞生物来说，这种危机并不是真正的危机，因为它们可能通过各种类型的共生来积极适应这种缺氧。我们通过实地调查、精确的环境评估、基因组学、精确的实验室培养和生物地球化学测量来验证这一假设。在相模湾、下田湾、太平洋（八户近海）、上越岛的浪名湖等地进行了实地研究。通过29篇论文、42篇演讲和其他科学界报告了结果。同时，这些知识通过互联网、研讨会、新闻发布等场合迅速向社会传递。

We hypothesized that the evolution of marine protists might been enhanced by active microbial symbiosis. The symbiotic relationships with microbes were suitable to survive during the crisis when the anoxic environments were dominant in the ocean. The crisis is not really crisis for eukaryotic unicellular organisms because they may potentially positively adaptable to this anoxia by various types of symbiosis. We have tested the hypothesis through field surveys, accurate environment assessments, genomics, precise laboratory culture and biogeochemical measurement. Field studies were carried out at Sagami Bay, Shimoda Bay, Pacific Ocean (off Hachinohe), Namako-ike lake of Kamikoshiki-jima island, etc. The results are reported through 29 papers, 42 presentations and others for science community. Meanwhile, the knowledge has immediately transferred to society by Internet, seminars, press release and other occasions.
