Pedigrees of neurobehavioral circuits: tracing the evolution of novel behaviors by comparing motor patterns, muscles, and neurons in members of related taxa.

Abstract excerpt

Comparisons of homologous elements in neurobehavioral circuits that have diverged during speciation to mediate different behaviors should reveal the nature of evolutionary changes in nervous systems. When the pedigree of a particular behavior can be traced-by comparing motor patterns and their neural substrates in related taxa whose phylogeny is known from other (non-neurobehavioral) criteria-divergent and...
