A couple of days ago I learnt about bees and temperature. When the temperature rises, each worker-bee feels it's too hot and starts flapping its wings. (When it's too cold they gather near.) But: - each bee is sensitive to different temperature threshold. This difference is genetically determined. - there's just one queen and 10-30 "fathers", so there's a mixture of sensitivities. Part of the bees feel it's too hot sooner than others, with a range of thresholds. Now the most interesting part: - a natural mixed population keeps the collective temperature with small oscilations. - an artificial population, selected so that all the bees have the same father, has much greater oscilations.
