Heredity versus environment

During simple/brief experiments Asa H's behavior is dominated by heredity, i.e., its innate algorithms plus any case base loaded as input (see my blog of 26 Aug 2013). During longer and more complicated experiments Asa H learns from the complex patterns it sees in the world and its behavior comes to depend more on environmental influences.  In some experiments the new case memory acquired during Asa's operation can exceed the size and complexity of the original Asa H software package.  As Asa lives longer nurture may come to be more important.  Is the same thing occurring in nature as animals live longer?
