PROBLEMS OF MODERN SCIENCE 



complex processes which occur as it is built up 

 from its earliest and simplest beginnings, and the 

 factors which determine its characteristically human 

 form. 



Anatomical researches are by no means con- 

 fined to man alone. Undoubtedly the vertebrate 

 animals, more particularly the so-called higher 

 vertebrates, are being as closely studied by the 

 anatomist as by the zoologist himself in order to 

 gain knowledge which will enable the former 

 to interpret human form, and more especially to 

 glean some insight into the hereditary factors 

 which influence it. Since the days of Darwin the 

 ancestry of man has been an attractive but at the 

 same time a most abstruse and complex study. 

 New evidence is constantly accumulating, evidence 

 gathered not only from the study of other animals, 

 but also from the study of remnants of humankind 

 and man-like forms which, lying buried and for- 

 gotten for long ages past, are unearthed from time 

 to time. Concerning this question contention 

 rages high ; its final solution, if solved it ever be, 

 is not yet in sight, and must be the outcome of 

 many years of patient discovery and research. 



Some parts of the body are comparatively 

 simple, others of bewildering complexity. The 

 more important the organ, and the more essential 

 the part it plays in the life of the individual, the 

 more intricate is its structure and the greater the
