Do birds have oval shaped eggs?
Birds that are good fliers tend to lay asymmetric or elliptical eggs,” says lead researcher Mary Caswell Stoddard from Princeton University. For example, while penguins also have elongated eggs, they could be the exception that proves the rule; they still need streamlined bodies to swim.
Why are eggs the shape they are?
