Drosophila melanogaster, commonly known as the fruit fly, has been a significant model organism in embryonic development research. Many of its genes that regulate embryonic development and their mechanisms of action have been crucial in understanding the fundamental principles of embryonic development regulation in many multicellular organisms ...
The fruit fly Drosophila melanogaster made the jump from nature to laboratory animal in 1901. At Harvard University, Charles W. Woodworth suggested to William E. Castle that Drosophila might be used for genetical work. [3] Castle, along with his students, then first brought the fly into their labs for experimental use.
Drosophila, usually the species Drosophila melanogaster – a kind of fruit fly, famous as the subject of genetics experiments by Thomas Hunt Morgan and others. Easily raised in lab, rapid generations, mutations easily induced, many observable mutations. Recently, Drosophila has been used for neuropharmacological research. [26]
One of the first model systems for molecular biology was the bacterium Escherichia coli, a common constituent of the human digestive system. Several of the bacterial viruses ( bacteriophage ) that infect E. coli also have been very useful for the study of gene structure and gene regulation (e.g. phages Lambda and T4 ).
Drosophila embryogenesis, the process by which Drosophila (fruit fly) embryos form, is a favorite model system for genetics and developmental biology. The study of its embryogenesis unlocked the century-long puzzle of how development was controlled, creating the field of evolutionary developmental biology . [ 1 ]
The leaf mining Scaptomyza flava, which is nested in the genus Drosophila phylogenetically, is an obligate leaf miner of mustard plants, including the model plant Arabidopsis thaliana [5] and is a major pest of salad brassicas in New Zealand and an emerging pest of canola in the UK.

The mechanisms involved are well seen in the anterior-posterior patterning of embryos from the model organism Drosophila melanogaster (a fruit fly), one of the first organisms to have its morphogenesis studied, and in the eyespots of butterflies, whose development is a variant of the standard (fruit fly) mechanism.
Thomas Hunt Morgan's work on Drosophila melanogaster found many small Mendelian factors for natural selection to work on. By 1912, after years of work on the genetics of Drosophila fruit flies, Thomas Hunt Morgan showed that these animals had many small Mendelian factors on which Darwinian evolution could work as if variation was fully ...
