Um, they talk about how this group of biological 12 researchers and chemists don't set out to locate this lignin, 13 but they're trying to understand the toughness of this form of algae and that's 14 how they discover it. Um, and they're sort of puzzled to find it, 15 um, because of what was previously known. 16 Then they describe, um, exactly how, 17 um, different scientists have theorized that this lignin came to 18 be in these particular organisms. 19 Um, and describe multiple theories for sort of what that process might have looked 20 like.
