Reply to comment by Wagamaga in Agriculture linked to changes in age-independent mortality in North America. The intensification of crop use occurred in two phases, the first of which led to a decline in human age-independent mortality, while the second is associated with a rise in it. by Wagamaga

Is the study saying that the first time around agriculture caused a shorter lifespan?

I don't think it has to do with lifespans exactly. I think the study suggests that the spread of native plant cultivation coincided, until 1000 years ago, with an increased likelihood that populations would die from age related causes as opposed to other causes (disease, famine, war, cataclysm, etc.).

But as populations introduced and became more dependent on maize specifically, the likelihood of dying from those non-age-related causes dramatically increased.
