   No, it was not correct.   
      
   His idea was that new species were born of changes originating in the   
   current generation's behavior.   
      
   For example if an animal constantly stretched its neck to reach high leaves   
   then a longer neck would be passed on to the next generation.   
      
   Epigenetics is like that only in a very limited sense.  Current stress can   
   cause a gene to be switched on or off.  That gene in that state is passed   
   on to the next generation and the function of that gene likewise passed on.   
      
   But that lasts for a generation or a few only.  In time the gene resumes   
   its previous on or off state.   
      
   It is not the origin of new species as was speculated by lamark.
