Question: Why don't identical twins look the same?

Hi Jemma, Well identical twins do look the same. Non-identical twins look different. Although, if we know twins over time, we can tell them apart if they are identical because they do have little differences! This is because during development in the womb, when the fertilized cell separates into two, they can sometimes go through different developments!
