8 THE STRUCTURE OF THE FOWL 



partly accounts for the fact that the domestic 

 fowl, though built on the lines of a flying and 

 not a running bird, does not possess any 

 notable capacity for flight. Haunting the 

 jungle as it does, the wild progenitor of the 

 common fowl makes little more use of its wings 

 than is necessary to allow it to rise from the 

 ground to its perch. Further, the effect of 

 domestication and artificial selection has 

 obviously been in a direction which discourages 

 flight.
