ABSTRACT
The evolution of inherited characteristics allows the species to adapt to changes in its environ ment over many generations: phylogenetic ad aptation. The learning of new behavior or new stimulus-response relations allows the indi vidual organism to adapt to changes in the en vironment over its lifetime: ontogenetic adapta tion (see Seay Sc Goddfried, 1978). In the case of phylogenetic adaptation, the environment causes some genetic variants among organisms (mutations) to survive and reproduce and oth ers to die before the organism has reproduced. This results in the phylogenetic evolution of the species through Darwin’s natural selection.
