Conjoined twins occur once every 200,000 live births. They develop from a single fertilized egg that fails to separate completely in the first few weeks after conception. Overall, 5-25% of conjoined twins survive after birth. Some notable examples include Chang and Eng Bunker from Thailand in the 1800s who were joined at the chest and had 21 children combined before dying hours apart, and Brittany and Abby Hensel who were born in 1990 in Minnesota and share parts of major organs but lead relatively independent lives.
