CHAPTER XI 



LOOKING BACKWARD 



LOOKING back over the history of the past, 

 it is very apparent that the animals now living 

 are very different from those of long ago, and 

 the farther back we go the greater do we find 

 these differences. Not only this ; the general 

 character of the animals was different. It is 

 not as if we merely found deer and bison, dogs 

 and cats, unlike those of the present time, but 

 we find animals totally unfamiliar to us, that 

 the eye of man never gazed upon in the flesh. 

 It has required an enormous length of time to 

 bring about these differences, but we can see 

 how, starting with the smallest and simplest of 

 animals, life has progressed ever onward and 

 upward, continually branching out into new 

 and higher forms.

 reason for these changes, and it might be well
