arose via time + chance on it's own? And why do some Flavors appeal to us and others don't? Or why do we even have the ability to taste the end result of this complex chain that produces Flavor?
I did but taste a little honey.... 1 Samuel 14:43
"That cherry flavor you enjoy in candy and soda is likely
a combination of aromatic and flavor compounds discovered through the
study of plants in laboratories far from cherry trees. It and the sweet
scent of your almond extract may actually be courtesy of a petunia
flower.
Biochemists track down the molecular recipes, called biosynthetic
pathways, that make these compounds and allow them to be bottled into
different flavors for the products we enjoy. 
When steps in the molecular
recipe are missing, chemicals outside of the natural processes are used
in commercial production, she explained.
“When chemical reactions are added in to fill the gaps, it can be a
problem,” said Dudareva, who also is director of Purdue’s Center for
Plant Biology. “It is much better and safer to use an entirely natural
pathway to a flavor compound, but it is difficult to discover all of the
steps.
Benzaldehyde has an especially puzzling biosynthetic pathway,
and it wasn’t completely revealed until now.” SciTechDaily
