If Evolution is true, then species are continually evolving ... and if so, there has to be species going from one thing to another ... like ocean to land or land to air .... something .... if you look at every living thing you'd notice they're complete ... a fruit fly will not evolve into an elephant or a rose into a fir tree ...
There are plenty of species around now, and plenty of them are related to us. Even the plant kingdom is related to us. Any intermediate steps would have been localized in small populations except for the ones that were successful, and most of the intermediate steps would have disappeared. Life has a way of disposing of its ancestors, leaving nothing.
