Caffeine
Why does the coffee plant contain caffeine?
We all know that coffee contains caffeine – but why?
It is, after all, poisonous to most common insects and slugs.
It turns out the caffeine is actually good for bees! Scientists believe that caffeine helps bees to remember specific plants so that they can keep returning to the same type of plant.
So, although people and bees are very different, caffeine has a similar effect on our neurological activities.
