How does the coelacanth help with research

Not only are those fins structured in pairs to move in a synchronized way,the coelacanth even shares the same genetic sequence that promotes limb development in land vertebrates.So although the coelacanth itself isn't a land-walker,its fins do resemble those of its close relatives who first hauled their bodies onto land with the help of these sturdy, flexible appendages,acting as an evolutionary bridge to the land lovers that followed.So that's how this prehistoric fish helps explain the evolutionary movement of vertebrates from water to land.
