Document Summary

Natural habitat: dense, shady, and mature deciduous woods (older woods) Food: bacteria and yeasts in fermenting substances rich in carbohydrates. Studied single-gene mutations for drosophila behavior: highly inbred-genetically uniform strains of flies then alter 1 gene at a time, feed chemical substance(ethyl methanosulfate) break up dna and then reassemble abnormally, 2 potential problems. Most molecules have isoforms-encoded by slightly different genes- each can do job separately. Knocking one isoform does not get rid of the rest. Genes are necessary to not only to encode proteins in the adult but also during development. Cannot be sure that the genetic lesion that appears to impaired learning has not actually impaired the development of a general feature of the circuitry necessary for learning. Experiments before benzer: dealt mainly with nonassociative learning in individual flies. After training exposed flies sequentially to the two odors in the absence of shock. (40 flies at a time)
