What is Drosophilinae?
[[File:Drosophila.jpg|thumb|230px|The fly]] The '''Drosophilinae''' are the largest [[subfamily]] in the [[Drosophilidae]]. The other subfamily is the [[Steganinae]]. A huge amount of research has shown the way the fly has evolved many species as it spread across the world. The genus ''[[Drosophila]]'' is [[paraphyletic]] because several genera (with many species), such as ''[[Zaprionus]]'', ''[[Scaptomyza]]'' and ''[[Lordiphosa]]'', are within the [[genus]]. What this means is that they have evolved from more standard ''Drosophila'' over time. This is pretty well supported by the evidence of their [[genome]].<ref>Beverley S.M. & A.C. Wilson 1984.
