(3) Selection was successful and resulted in two lines differing by an average of six aristal branches.
(4) These thermoreceptors are often coupled with hygroreceptors; however, we can only speculate whether the second dendrite of the aristal organ also has this function.
(5) It is concluded that the number of aristal branches in Drosophila is a neutral trait (i.e., not subject to natural selection) under laboratory conditions.
(6) Polygenic control of aristal morphology is indicated by a gradual response to selection and low realized heritabilities.
(7) Barrier was found to be related to aristic, expressive creativity which seems to be related to interest in human interactions, but unrelated to creativity associated with scientific endeavors and unrelated to creative receptivity (i.e., purest adaptive regression).
(8) Two populations of D. melanogaster were selected for increased and decreased numbers of major aristal branches.
(9) They lie in the center of the disc and correspond to the neurons of the adult aristal sensillum.
(10) The fine structure of the aristal sensory organ was studied in detail in the fruitfly (Drosophila) and for comparison in the housefly (Musca) and the blowfly (Calliphora).
(11) It is generally adopted that the homoeotic gene proboscipedia causes the transformation of the distal parts of proboscis into corresponding tarsal or antennal (aristal) segments.
(12) Correlations between aristal morphology and behavior found in other selection experiments by previous investigators were likely due to linkage disequilibria.
(13) The transformation of oral lobes of proboscic into the leg is most conspicuous at 29 degrees C, while at 16 degrees C the substitution of tarsal structures by aristal ones is observed more frequently.
(14) Shifts down yielded leg tissue at the aristal base, which retreated with later shifts.
(15) Sometimes the distal parts of the homoeotic leg (segments of tarsus, claws) can coexist with or be substituted for by the aristal filaments.
(16) This suggests that neither larval leg neurons nor early aristal neurons are essential for the outgrowth of subsequent afferents.
(17) In Drosophila, the aristal sense organ consists of 3 identical sensilla that terminate in the hemolymph space of the aristal shaft, and not in an external cuticular apparatus.
(18) The aristal sense organs in Musca and Calliphora are similar to those in Drosophila, but contain more sensilla (12 in Musca, 18 in Calliphora.
(19) When selection was relaxed for 19 generations, the number of aristal branches did not revert to the number in the control line.
(20) Changes in aristal branching did not appear to have a consistent influence on geotaxis, although there was a tendency for flies with fewer aristal branches to be geonegative.
