Modern honey bees actually have greater genetic diversity than their ancestors. This finding is the exact opposite of what was expected! Scientists believed that bees were becoming increasingly less diverse genetically and that was one of the reasons their population was declining. High levels of diversity have been shown to be critical in maintaining healthy hives as it is associated with lower pathogen loads and greater adaptability to changing environmental conditions.
Bees have 5 eyes: two big ones in the front of their head and three smaller ones on top of their head, which help them fly properly.
