How did animals moved from water to land?

Life transitioned from water to land when the Tiktaalik roseae, a type of fish existed that lived from 417-354 million years ago and resembled a crocodile. It 's remains we're discovered on Ellesmere Island, Canada. Findings have shown that the Tikaalik roseae was able to breathe using both gills and lungs which were protected by a rib cage. We can conclude that this animal went from water to land due to these innovative changes.
