Drosophila (/ d r ə ˈ s ɒ f ɪ l ə, d r ɒ-, d r oʊ-/ [1] [2]) is a genus of fly, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit.
Drosophila melanogaster is a species of fly (an insect of the order Diptera) in the family Drosophilidae. The species is often referred to as the fruit fly or lesser fruit fly , or less commonly the " vinegar fly", " pomace fly", [ a ] [ 5 ] or " banana fly". [ 6 ]
Homeobox (Hox) gene expression in Drosophila melanogaster. Drosophila melanogaster is an important model for understanding body plan generation and evolution. The general principles of Hox gene function and logic elucidated in flies will apply to all bilaterian organisms, including humans. Drosophila, like all insects, has eight Hox genes ...
Experimental evolution is the use of laboratory experiments or controlled field manipulations to explore ... and multicellular eukaryotes like Drosophila, ...
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 ]
Additionally, Drosophila subobscura, also within the genus Drosophila, has been reputed as a model organism for evolutionary-biological studies, [3] along with D. sechellia for the evolution of host specialization on the toxic noni fruit [4] and Scaptomyza flava for the evolution of herbivory and specialist on toxic mustard leaves.

A total of six series of experiments were conducted with the fruit fly Drosophila melanogaster, using three to five individuals of each sex. Each trial ran for three or four days. Some ran to completion without the transfer of the Drosophila from one environment (bottle) to another. In the others, Bateman transferred the flies and their eggs to ...
Waddington called the effect he had seen "genetic assimilation". His explanation was that it was caused by a process he called "canalization".He compared embryonic development to a ball rolling down a slope in what he called an epigenetic landscape, where each point on the landscape is a possible state of the organism (involving many variables).
