The Science of Identical Twins: Genetics, Environment, and “Twintuition”
From the mythical Romulus and Remus to the “Twinnies,” Paula and Brigette Powers, identical twins have captivated the public imagination.Many non-twins have wondered what it would be like to switch places with a sibling who looks just like them.
Twins Research Australia works with 75,000 twins to explore their similarities and differences and how these relate to health outcomes. Professor Sarah Wilson and another colleague recently participated in the TV show “Australia’s Most Identical,” where 100 sets of twins competed to be named the nation’s most identical pair.
Identical twins, known as monozygotic twins, develop when one fertilized egg splits into two embryos, typically within the first two weeks after conception. The timing of this split determines whether the twins share a placenta or amniotic sac. Earlier splits lead to more independent development, while later splits can result in shared structures or, in rare instances, conjoined twins.
While scientists once believed this division was a simple process, newer theories suggest it might potentially be more complex. Some researchers propose that two cell clusters develop independently within a single embryo, but the exact mechanism remains unclear.
Adult identical twins who have spent their lives together often report “twintuition”-an intuitive sense of what their twin is thinking or feeling. This can even manifest as synchronized speech, leading some to believe in “twin telepathy.”
