Summarize Argument: Phenomenon-Hypothesis
Scientists hypothesize male sage grouse inflate their air sacs during a courting ritual so that female sage grouse can select healthy mates. They provide no evidence for this claim.
Notable Assumptions
The scientists assume that there's some way for female sage grouse to determine which males are healthy based on their inflated air sacs. The scientists also assume the female sage grouse are more likely to choose the healthy males.
