That is the simplest way to determine whether a child will have a Quirk. Superhumans are more evolved than humans, and as such they are bone with one joint in their pinky toe, rather than two like a normal human due to their bodies being more streamlined than normal humans.
Though it is rather simple to discern whether a person will have a Quirk or not, this is done so by a simple x-ray of a child's foot.
No one knows what causes these Quirks, but before long the supernatural became the norm as nearly 80% of the world's population possesses some uncanny ability. Then, as time passed, similar phenomena had happened all over the world, and soon the majority of the population had obtained superhuman powers. This baby came to be known as the Luminescent Baby. The first incident, the first occurrence of the Quirks was in Keikei City, China, where an extraordinary baby was born with a unique power. Some people were born with gifts that others don't possess.
