[edit] Summary

Fruit fly speciation obsrerved in the lab. Improved to be anatomically correct. Based on experimental description in this gif file:

http://evolution.berkeley.edu/evolibrary/images/evo/drosophila_experiment.gif

Diane Dodd demonstrated allopatric speciation by reproductive isolation in Drosophila pseudoobscura fruit flies after only eight generations using different food types, starch and maltose.^[1] Dodd's experiment has been easy for many others to replicate, including with other kinds of fruit flies and foods.^[2]
