6 inch female skeleton update

My aunt, half Cherokee (not the most attractive person outwardly) half white European suffered back pain. She had surgery when she was around age 50 and the surgeons extracted a 6 inch female skeleton with hair which they stated was as a result of this fetus migrating outside the uterus and being incorporated into the would-be twin. Considering that we are mostly mixed DNA beings and that from the smallest of the small (1 foot in height - Dona) to more than 9 feet (Quayle) alive today ranging in hair color from translucent to black and orange. If another being came to our planet and looked at the variation of bi-pedal beings would they return to home and say - nope just one species homo sapien sapien. Haha hehe really, science - gotta love us. As Ren says 'Idiots'.
