And? What species are around?

Tousle, not tussle. A tussle is a fight.

Fun fact: your “fun fact” is a myth. Artificial banana flavor is not “based off Gros Michael”. The flavoring is not some sort of recipe that was based off of anything. It’s a single chemical found in all bananas. It’s a coincidence that Gros Michael tastes more like fake banana flavoring than other bananas, but all bananas contain that same ester: isoamyl acetate. It’s just that Gros Michael has more of it.

However, if you dig in to this tale a little it soon becomes clear that there is little or no verifiable source that artificial banana is based on Gros Michel. “It sounds very, very unlikely to me,” says synthetic organic chemist Derek Lowe.

So please stop repeating this myth.

In addition, you’re completely wrong about artificial vanilla flavor. It is the exact ester found in real vanilla, and it is by far the most dominant flavor in real vanilla. It tastes exactly like vanilla minus a few extra subtle notes.

It’s a recurring column called “Word of the Week”, and it’s discussing the origin and classical usage of the word “parasite”. What’s so hard to understand about that?
