Respiratory Biology: They Would Be Giants
A recent study has shown that respiratory structures are disproportionately oversized in larger insects, and that oxygen supply to leg muscles may be physically constrained in the largest modern insects. High oxygen concentrations during the Carboniferous may have alleviated these physical constraints allowing the evolution of gigantic arthropods.

Increasing evidence supports the hypothesis that the fallopian tube is the site of origin for the vast majority of high-grade serous carcinomas. Our growing understanding of the pathogenesis of this disease offers a rare o...
متن کاملGod would be a costly accident: Supernatural beliefs as adaptive
I take up the challenge of why false beliefs are better than “cautious action policies” (target article, sect. 9) in navigating adaptive problems with asymmetric errors. I then suggest that there are interactions between supernatural beliefs, self-deception, and positive illusions, rendering elements of all such misbeliefs adaptive. Finally, I argue that supernatural beliefs cannot be rejected ...
