Even if you don't know much about the Duggars, most people can pick out who the oldest daughters are. However, when it comes to the Duggar sons, it gets kind of tricky. Unlike Jill, Jessa, and Jinger, who all have uniquely different faces, the men in the family all have the same face — and it looks just like Jim Bob's.

Even if a Duggar boy starts off with a unique face that stands out, like Josiah's, as soon as they hit the ripe age of 20, they start morphing into their father at an alarming rate, making it even harder for us to tell them all apart. We don't know if it's their genes or because they're all forced to be fathers at the age of 20, but it's all oddly fascinating. Below, a look into how the Duggar boys have evolved over the years and basically all look so much like their dad now.
