Apparent Instances and Objections 161 



disembarked for the first time upon uninhabited islands 

 the animals have not often any fear of them, but after 'a 

 very few generations the fear of man has become an 

 inborn instinct. 



Weismann and his followers could object here also that 

 this fear of man is not even now an inborn character, but

"The co-ordination, arrangement, and connections of 

 the ganglion cells which innervate the muscles of speech," 

 says Roux, "are already inborn in us to such an extent

 for example Europeans even when brought among the 

 Namas while still children never learn their language as 

 perfectly as the Namas themselves, or do so only with

This does not prevent any one fundamentally opposed 

 to the inheritance of acquired characters from objecting 

 that the European language spoken by the parents and 

 ancestors of the child may not be the cause of these dis- 

 positions and inborn connections of the ganglion cells but 

 rather the effect ; in other words, it is not the use of this 

 or that speech which develops such and such inheritable 

 connections; but rather the presence of certain connec- 

 tions due to natural selection has produced certain 

 peculiarities in the character of the language of a given 

 human race.
