Scientists discovered why mice fear bananas

Bananas stress male mice, say researchers.
Scientists discovered it while examining male mice's behaviour to pregnant and nursing females.

Researchers found that bananas' chemical components increased stress in male mice.

In close proximity to late-pregnant or nursing female mice, male mice show tension and stress-induced pain inhibition

The McGill University researchers also observed that pregnant and nursing female mice reacted to stranger male mice with hostility and urine marking.

Male mice are infamous for killing pups. Pregnant and breastfeeding female mice produce chemicals that repel males.

Professor Jeffrey Mogil told Live Science that rodents and many other species rely on their smell capabilities.
