RELATION OF ANIMALS TO MAN 25

end would justify. To meet the requirements of domesti- 
cation animals must breed in captivity, thrive under the 
artificial conditions impo8ed, and be of service to man.

completely domesticated, is an artificial production. It has 
lost its old ability to care for itself. Under its new en- 
vironment it depends on man for its parents, food, shelter, 
protection and care.
