No evidence of multi-origin.
- Parallels between natural selection in the cold‐adapted crop‐wild relative Tripsacum dactyloides and artificial selection in temperate adapted maize. Artificial selection for temperate adaptation in maize involved the same genes as natural selection for temperate adaptation in Tripsacum.
There’s been a spate of papers on reforestation just lately and I was despairing of being able to keep track of them, let alone read them. But along comes Jonah Busch, Chief Economist at Earth Innovation, to make sense of all the maps in a couple of tweets:
Here are maps of reforestation's potential, feasibility and benefits, and costs pic.twitter.com/fK3jyFPjSr

Here are the papers:
- Potential: The global tree restoration potential.
- Opportunities: Global restoration opportunities in tropical rainforest landscapes.
- Costs: Potential for low-cost carbon dioxide removal through tropical reforestation.
LATER: There’s a nice round-up of two of the studies in Mother Nature Network. Bottom line is in the title: Massive reforestation might be the moonshot we need to slow down climate change. That doesn’t mean forests are a silver bullet, though.

- Understanding food systems drivers: A critical review of the literature. Spoiler alert: urbanization, raise in consumer income, population growth, attention paid to diet & health issues, technological innovations, intensification and homogenization of the agricultural sector, increase in frequency and intensity of extreme events, general degradation in soils and agro-ecological conditions, improved access to infrastructure and information, trade policies and other processes influencing trade expansion, internationalization of private investments, concerns for food safety. I guess diversity is in there somewhere.
