I would be satisfied to consider reverse engineering over a few years, a
few biological steps, or a thousand years from anyone species to its
closest relative.

can do reverse engineering from what we now observe to a considered initial
condition, say the Big Bang. For an isolated system, this would entail the
ability to explain everything we now know, say free will, consciousness,
human rationality, etc., in terms of purely physical entities. This is indeed
a tall order.
