But there are at least twice as many species in Newfoundland which show a tendency toward darkness. Here, in Newfoundland, one can observe bird-races in the making! It is impossible to say whether this darkening of the coloration is an acquired Character induced by the humidity and bleakness of the country, or whether the environ ment is one which fosters all variations towards darkness, which Variations may themselves have arisen independent of the environ ment. No matter where the truth lies, these tendencies exist, and in these Newfoundland birds, we have represented the Very beginning. Of future geographic forms.
