The fruit fly (Drosophila melanogaster) has 4 distinct life stages:
    -Embryogenesis
    -Larval
    -Pupa
    -Adult

-Examined a string of 66 sequential time points
-86% of 4,028 genes change expression during development
-Many of these are expressed in 2 waves:
    -Embryonic resembles Pupa
    -Larval resembles Adult

-These findings can act as a baseline
-Allows study to find the affect of one mutation things such as pathways, sex determination, hormonal regulation of metamorphosis, aging, diet, and sexual behaviour!
