Carrier's constraint : ウィキペディア英語版
Carrier's constraint
Carrier's constraint is the observation that air-breathing vertebrates which have two lungs and flex their bodies sideways during locomotion find it very difficult to move and breathe at the same time, because the sideways flexing expands one lung and compresses the other, shunting stale air from lung to lung instead of expelling it completely to make room for fresh air.
It was named, by English paleontologist Richard Cowen, for David R. Carrier, who wrote his observations on the problem in 1987.
==Consequences==
Most lizards move in short bursts, with long pauses for breath.
Around the Late Triassic period, animals with Carrier's constraint were preyed on by bipedal species that evolved a more efficient stride.
