By a process of elimination, therefore, the three researchers were left with the conclusion that, by pushing metabolic rates up, tropical heat causes more mutation and thus more speciation.

因此，三位研究人员得到如下结论：由于代谢速度的提升，热带地区的热量引起更多的突变，也因此形成更多的物种。

Researchers are reporting that the "Asian Flush" mutation cropped up just as rice was first being domesticated, and it may have protected early farmers from the harms of drinking too much.

研究者发现‘亚洲人红脸’的变异在水稻第一次被驯化时产生，它可能保护了早期的农民不会因为饮酒过度而受损。
