0038 I summarize.

Chapter four covers human evolution.

Haarsma engages in a discussion of human evolution_2H as if it does not intersect with original sin_2V. Yet it does, otherwise Haarsma would not write a book about it.

Haarsma’s titular question_2V, “When did sin begin?”, should place the hypothesis of the first singularity_2H side by side with the doctrine of original sin_2V.

But, since Haarsma is not aware of the hypothesis of the first singularity, the term, “human evolution”, goes into the slot for actuality_2H for the normal context of natural change_3H.

This does not work, of course, and leads to a winding path, back to the crucial intersection between the first singularity_2Vand original sin_2H.

0039 The path starts by asking, “What contributing actuality_2V, in a theological framework_3V, corresponds to human evolution, as Haarsma discusses the topic?”

The answer comes from Thomas Aquinas’s suggestion that original sin is the lack of original justice.  Original justice is entangled with human evolution.

0040 If human evolution_2H is one of the actualities in an intersection, the corresponding actuality is not original sin_2H.  The corresponding actuality is really the stuff of the Creation Story_2V.

The structure of Haarsma’s text validates this suggestion.

Chapter four, titled, “Human Evolution”, is preceded by chapter three, “Suffering and Death Before Humans”, and followed by chapter five, “The Soul, the Imago Dei and Special Divine Action”.   Chapters three and five point to Genesis 1:26-31.
