Evolution: arriving on land (Evolution)

DAVID’s comment: why did seagoing animals have the ability to breath air in advance of the mass extinction? Good luck or God?

dhw: Those that had already ventured onto land had already adapted to life out of the water, and those that hadn’t adapted went extinct. Sounds perfectly natural to me.

You are assuming an advanced adaptation. Either an air bladder or rudimentary lungs must be available to stay awhile on land. How does adaptation occur in such an unfriendly environment? Multiple beneficial mutations are necessary. Not by chance.
