epistatic mutns, or the creation of new genes. A common result for
organismic design is modularity. By modularity we mean a genotype-phenotype
map in which there are few pleiotropic effects among characters serving
different fns, with pleiotropic effects falling mainly among characters
that are part of a single functional complex. Such a design is expected to
improve evolvability by limiting the interference between the adaptation of
different fns. Several popn genetic models are reviewed that are
intended to explain the evolutionary origin of a modular design. While our
current knowledge is insufficient to assess the plausibility of these models,
they form the beginning of a framework for understanding the evolution of the
genotype-phenotype map."

induction of developmental variation by novel environments of this species's
expanding range was followed by homeostatic channelling, phenotypic
accommodation & directional cross-generational transfer of a subset of
induced developmental outcomes favoured by natural seln. These results
emphasize three principal points. First, contemporary novel adaptations
result mostly from reorganization of existing structures that shape newly
expressed variation, giving natural selection an appearance of a creative
force. Second, evolutionary innovations & maintenance of adaptations are
different processes. Third, both the Baldwin & parental effects are probably
a transient state in an evolutionary cycle connecting initial phenotypic
retention of adaptive changes & their eventual genetic determination &, thus,
the origin of adaptation and evolutionary change."

adaptation. In a different intellectual domain, learning theory links
incremental adaptation (e.g., from +ve &/or -ve reinforcement) to intelligent
behaviour. Specifically, learning theory explains how incr. adaptation can
acquire knowledge from past experience & use it to direct future behaviours
toward favourable outcomes. Until recently such cognitive learning seemed
irrelevant to the 'uninformed' process of evoln. In our opinion, however,
new results formally linking evolutionary processes to the principles of
learning might provide solutions to several evolutionary puzzles - the
evoln of evolvability, the evoln of ecological organisation, & evolutionary
transitions in individuality. If so, the ability for evoln to learn might
explain how it produces such apparently intelligent designs."
