Just like us, fruit flies dwell on difficult decisions, according to a study published in the journal Science.
They spend more time choosing between a strong and a weak smell if the difference is small.
The research links this deliberation to a particular gene, FoxP, and the activity of fewer than 200 neurons.
Mutations in FoxP, also associated with cognition and language in humans, made flies' decisions even slower without affecting which choice they made.

want to go outside...
Through the open door they smell danger. Through the incomprehensible glass (to them) they don't.
Anyways, our oldest dog likes to catch flies, but she's rather lazy about, she will maybe stand up and take a few quick steps and then go back to napping whether she catches the fly or not.
But our youngest dog makes a huge sport of it running around the room, jumping on furniture, bouncing off the walls, knocking things down until her prey is caught.
