The bigger the better

In the 1950’s, Nikolaas Tinbergen, a Dutch ethologoist, discovered that when a bird has a choice of brooding over their small egg or a larger egg even of much larger bird the bird will sit on the larger egg.  This was found to be with the oystercatcher, herring gull and greylag goose birds.  In butterflies, when the male is courting he will be drawn to the female who flaps wings faster.

Humans also like the bigger is better.  Sugar, salt and fat along with our entertainment are what we gravitate to rather than the smaller amount.  The more, the bigger, the better.
