Why is wood glue so strong?

Its strength comes from its adhesion to the material and its own strength. While yellow wood glue does dry fairly hard, epoxy is a much stronger material after it has fully set. And while setting, it doesn't shrink, so it will bridge gaps well. It doesn't have to be clamped and is not easily absorbed into the wood.
