"I have not seen this posted , so I am wondering ... Can anyone give me an example of a transitional fossil that shows proof of one species changing into another ?"
"Besides asking what you mean by `` proof `` and what `` proof `` will be acceptable , I would also like to know what you mean by transitional . I can actually do better than show you a transitional fossil . I 'll show you a living transitional between two species . Go to almost any body of water in northern North America in the summer , or along the coasts of southern North America in the winter and look for birds like this . http : //www.martinreid.com/Image % 20files/HEGU18B.jpg There you go . The American herring gull ( Larus argentatus smithsonianus ) A transitional between two species . These birds range to the east across Greenland , Iceland , and into northern Europe . It looks about the same in Europe . http : //www.birdguides.com/html/vidli ... 015a001_j2.jpg They also range to the west from Alaska into Siberia , across Siberia and Russia all the way to northern Europe . But as you go further and further west their appearance begins to change . But there is never a place where neighboring populations can not and do not interbreed . But in northern Europe the populations from the west look a bit different . http : //www.birdguides.com/html/vidli ... 018a001_j2.jpg That 's the Lesser black-backed gull ( L. fuscus ) . Even though it shares the same range as the herring gull it does not interbreed with herring gulls . So here is one large population that has become two different species at the extremes of its range , and those extremes overlap . So the American herring gull is a transitional between the Herring gull and the Lesser black-backed gull . It is even thought that the original population from which all of these birds descended lived in North America ."
