FIGURE NO. 14 



EVOLUTION AMONG PIGEONS 



This figure shows (I) the wild Rock Dove (Columba livia), the 

 ancestor of all the races of domesticated pigeon, e.g. (II) Turbit, 

 (III) Jacobin, (IV) Pouter, (V) Fantail. As in similar cases, man 

 has selected mutations or variations that pleased him, and estab- 

 lished stable races, breeding true. Similar mutations are paired 

 together; divergent or reversionary individuals are eliminated.
