Evolution is an ancient theory. Its modern 

 renaissance, with which alone we are here con

 elapsed and Darwin s fading star was to be again 

 outshone by the reappearance of the Lamarckian 

 comet, under a new form and under the new name 

 of Neo-Lamarckianism. Sir Bertram Windle 

 offers a very apposite illustration of the differ

 in the case of the giraffe as explained according 

 to their respective views: 



The giraffe is provided with an extraordinary long neck and 

 Very tall forelegs. These he acquired, according to Lamarck s 

 view, by constantly stretching after the foliage of trees, on 

 which he feeds, and by ever reaching after higher and yet

 giraffes were by reason of causes inherent in the embryo pro-
