The Secret behind Pearls’ Amazing Symmetry has been discovered

The Secret behind Pearls’ Amazing Symmetry has been discovered

When a speck of sand, dirt, or food particles get lodged within a mollusk, it forms a pearl. The creature detects the errant particle and proceeds to coat it with layers of aragonite and conchiolin, the minerals and proteins used by mollusks to construct their shells. However, until today, scient.....
