COMPARATIVE PHYSIOLOGY AND BIOCHEMISTRY 



Similar facts have been worked out in amphibians for some aspects of 

 blood physiology and excretory physiology. Thus it appears that the prin- 

 ciple of recapitulation can give meaning to many otherwise inexplicable 

 phenomena of biochemistry and physiology. 



Wald has said that, "without the rationalizations of phylogeny, compar- 

 ative biochemistry is little more than a catalogue." * But evolutionary 

 ( phylogenetic ) considerations do give meaning to this great and funda- 

 mental bodv of data, and this is cogent evidence for evolution.
