>> There are plants that don’t appear green but… Seems like a fairly casual dismissal of data points that aren’t fitting the hypothesis.

  I think the rest of that sentence tries to explain the dismissal: >> There are plants that don’t appear green, like the copper beech, because they contain pigments like carotenoids. But those pigments are not photosynthetic: They typically protect the plants like sunscreen, buffering against slow changes in their light exposure The reason for non-green is not related to photosynthesis but some other process

    This what I mean. The reason why some data points do not fit the hypothesis is thrown in rather casually, without any references.
