The nature or nurture fallacy honey bee example shows that it is a mistake to say that some behavior phenotypes are more genetic than others. Dna is both inherited and environmentally responsive. Environmental signals such as those provided by juvenile hormone and ethyl oleate influence gene activity. When a gene is turned on or off by changes in the environment, changes in protein output can directly or indirectly alter the activity of other genes within affected cells. Gene- environment interactions are responsible for the construction of every trait. Development of every attribute of every living thing requires the information contained in large numbers of genes and expressed in a multitude of gene-environment interactions. Neither genotype nor environment is more important than the other. David sherry provided captive chickadees with a chance to store food in holes drilled in small trees placed in an aviary.
