CHAPTER XXII. 



OBJECTIONS TO THE HYPOTHESIS OF TRANSMUTATION CONSIDERED. 



STATEMENT OF OBJECTIONS TO THE HYPOTHESIS OF TRANSMUTATION 

 FOUNDED ON THE ABSENCE OF INTERMEDIATE FORMS - GENERA OF 

 WHICH THE SPECIES ARE CLOSELY ALLIED OCCASIONAL DISCOVERY OF 

 THE MISSING LINKS IN A FOSSIL STATE - DAVIDSON'S MONOGRAPH ON 

 THE BRACHIOPODA - WHY THE GRADATION AL FORMS, WHEN FOUND, 

 ARE NOT ACCEPTED AS EVIDENCE OF TRANSMUTATION GAPS CAUSED 

 BY EXTINCTION OF RACES AND SPECIES - VAST TERTIARY PERIODS 

 DURING WHICH THIS EXTINCTION HAS BEEN GOING ON IN THE FAUNA 

 AND FLORA NOW EXISTING - GENEALOGICAL BOND BETWEEN MIOCENE 

 AND RECENT PLANTS AND INSECTS - FOSSILS OF OENINGHEN SPECIES 

 OF INSECTS IN BRITAIN AND NORTH AMERICA REPRESENTED BY 

 DISTINCT VARIETIES FALCONER'S MONOGRAPH ON LIVING AND FOSSIL 

 ELEPHANTS FOSSIL SPECIES AND GENERA OF THE HORSE TRIBE IK 

 NORTH AND SOUTH AMERICA - RELATION OF THE PLIOCENE MAMMALIA. 

 OF NORTH AMERICA, ASIA, AND EUROPE SPECIES OF MAMMALIA, 

 THOUGH LESS PERSISTENT THAN THE MOLLUSCA, CHANGE SLOWLY 

 ARGUMENTS FOR AND AGAINST TRANSMUTATION DERIVED FROM THE 

 ABSENCE OF MAMMALIA IN ISLANDS IMPERFECTION OF THE GEOLO

most obvious and popular of the objections urged 

 -L against the theory of transmutation may be thus ex 

 pressed : If the extinct species of plants and animals of the 

 later geological periods were the progenitors of the living 

 species, and gave origin to them by variation and natural 

 selection, where are all the intermediate forms, fossil and 

 living, through which the lost types must have passed during 

 their conversion into the living ones ? And why do we not 

 find almost everywhere passages between the nearest allied
