This physiological adaptation allows them to uptake water and avoid dehydration when temperatures get too high.

This physiological adaptation shows in nearly a hundred other species, including owlet-nightjars, nightjars, and woodswallows.

These studies have helped expand the understanding of bacterial catabolism, noncatabolic physiological adaptation to organic compounds, and the evolution of large bacterial genomes.

Therefore, the effects of flight duration on physiological adaptation and readaptation could be examined.

Hypotheses to explain the evolution of biomineralization include physiological adaptation to changing chemistry of the oceans, defense against predators and the opportunity to grow larger.
