Twins are cool. Although it doesn’t quite seem like they can communicate through brain messages, some twins have some freaky similarities!
As a fraternal twin myself, I have always wondered why my brother and I are so alike but so different at the same time. Identical twins, on the other hand, are like clones of each other; on average they share 98% of their DNA! This is astounding compared to an average of 50% in fraternal twins.
Even being a twin, I was pretty amazed by some of the identical twin facts I’ve come across. For instance, twins can have different dads, and even be of different races! I thought I was unique as a twin.
Check out some more of these wacky identical twin facts:
- The birth rate for twins in the United States has increased 76% since 1980.
- There’s a gene for twins! Some women are more susceptible to hyper ovulation, which increases the likelihood of having twins.
- Twins can be born years apart! Through in-vitro fertilization, twin embryos can be made. If the embryos are frozen, one twin can be born years apart from the other!
- Twins can have secret conversations! Idioglossia — a language often created and shared between twins, allows them to communicate without anyone else understanding.
- About 40% of twins invent their own languages.

Turns out being a twin a was a little bit more unique than I thought.
