Bumblebee Megacolony

A study by the Universidad Nacional Autónoma de México explored the effects of food availability on the colony size and body size of 21 bumblebee taxa. Not surprisingly according to the study, the size of a colony is directly affected by food availability: The more food, the larger the colony. However greater food availability does not necessarily lead to larger individual body size within larger communities. On the contrary, the bumblebee study shows a negative relationship between colony size and the size of the individual. Larger colonies as a result of abundant food leads to smaller individual bees within the bigger colony. In other words; the larger the colony the smaller its inhabitants. That could be good news in relation the dramatically increased size and number of cities and the size of its inhabitants. Are megacities functioning as incubators for a smaller human species?
