While dogs do not at all,
Horses see just shades of grey
As they through pastures stroll...
Now a brand new study
Of fruit flies, has revealed
The shimmering colors of their wings
Are there for sex appeal:
The rainbows in male fruit flies' wings,
Like oils slicks, as they watch,
The females see these brilliant hues,
And like them very much...
A fruit fly's life may be quite short,
But for better or for worse,
Yet seeing colors, it may enjoy
Life better than a horse.
