Twins and Other Extraordinary Kinships: The Science and the Fascination



Twins have a universal fascination for both scientific professionals and members of the general public. Why this is the case has been a matter of some debate, but several explanations will be suggested. Next, an overview of twin types (identical and fraternal) and the fascinating variations displayed by each type are described and illustrated (e.g., twins reared apart, biracial twins, twins with different fathers) with compelling data and case studies. Some curious, twin-like twosomes are also included, given that they are scientifically informative, as well as fascinating (virtual twins, unrelated look-alikes, switched at birth pairs). Twin research continues to grow and to flourish as more twins are being born and researchers representing diverse disciplines, such as politics, religious studies, and economics, are embracing a twin-based approach to better understand their observations.
