Are there any recorded cases of conjoined triplets?
Step 1. An egg is fertilized
Step 2. The egg begins to spilt, but the separation is incomplete, resulting in conjoined twins
Step 3. One of the two conjoined eggs begin to spilt a second time, and the separation is incomplete once again, resulting in three conjoined embryos
is this possible? has it ever happened? if so, how long did they survive?
