A set of conjoined twin girls have been successfully separated after sharing parts of their hearts for almost two years. Conjoined twin girls Hope and Anna Richards were successfully separated last monthJill Richards held her conjoined twin girls, Anna and Hope, just before their surgery. Conjoined twins are very rare, making the causes behind the condition difficult to study and as-of-yet unclear. Conjoined twins are caused by a fertilised egg beginning to split into two embryos a few weeks after conception, but the process stops before it is complete. For many sets of conjoined twins, separation is simply not an option because they share too many essential organs and blood vessel connections.
