from natural causes. And those typical similarities which are 

 traceable under adaptive modifications, must obviously exist if, 

 throughout creation in general, there has gone on that continuous 

 superposing of modifications upon modifications which goes on in

[I might with propriety have added to the foregoing criticisms, 

 the remark that Professor Owen has indirectly conferred a great 

 benefit by the elaborate investigations he has made with the view of 

 establishing his hypothesis. He has himself very conclusively 

 proved that the teleological interpretation is quite irreconcilable 

 with the facts. In gathering together evidence in support of his 

 own conception of archetypal forms, he has disclosed adverse 

 evidence which I think shows his conception to be untenable. 

 The result is that the field is left clear for the hypothesis of Evo- 

 lution as the only tenable one.]
