A 'universal formula' to describe the shape of any bird's egg has been created by scientists, who say it could one day shed light on why and how eggs first evolved. The new formula for egg shape is based on four parameters: egg length, maximum breadth, shift of the vertical axis, and the diameter at one quarter of the egg length. It is based on four parameters: egg length, maximum breadth, shift of the vertical axis, and the diameter at one quarter of the egg length. This formula can theoretically describe any bird's egg that exists in nature. It involves measuring the length, the maximum breadth, distance between lines corresponding to maximum breadth and half the length, and the diameter.
