- Duration of agriculture and distance from the steppe predict the evolution of large-scale human societies in Afro-Eurasia. Large, complex human societies arise where there is a long history of agriculture and war; and not, interestingly, where potential productivity is highest.
- Diet, Mobility, Technology, and Lithics: Neolithization on the Andean Altiplano, 7.0–3.5 ka. It seems the rise of large, complex societies arose in the Andes is associated with the change in projectile technology from atlatl to archery.
- Three-dimensional X-ray-computed tomography of 3300- to 6000-year-old Citrullus seeds from Libya and Egypt compared to extant seeds throws doubts on species assignments. Meanwhile, across the Atlantic, people were snacking on watermelon seeds.
- From the earliest farmers to the first urban centres: a socio-economic analysis of underground storage practices in north-eastern Iberia. You can track socioeconomic changes in ancient Iberian cultures (c. 5600–50 BC) via the size and morphology of their grain silos. No word on projectile technologies nor watermelons though.
- Re-evaluating Scythian lifeways: Isotopic analysis of diet and mobility in Iron Age Ukraine. Meanwhile, back on those steppes, 700-200 BC, some people were relatively settled, with their agro-pastoralism and millet agriculture, while others moved. So much for warlike nomads. Must have had watermelons by then, surely.
- Why were New World rabbits not domesticated? Because they’re solitary, dispersed and there’s too many different types. Most North American evidence of management comes from Teotihuacan, ~AD 1–550.
- Estimating the age of domestic fowl (Gallus gallus domesticus L. 1758) cockerels through spur development. In Britain, Iron Age and Roman cockerels died way too old to have been kept for meat, and were thus probably also used for rituals and cockfighting. No word on the Killer Rabbit of Caerbannog.
- The earliest water buffalo in the Caucasus: shifting animals and people in the medieval Islamic world. The water buffalo came to Azerbaijan with Islam in the 7-9th centuries.
- Collagen fingerprinting traces the introduction of caprines to island Eastern Africa. Goats from the 7th century CE, sheep a couple hundred years later. No word on water buffaloes.
- An illustrated review on manifestation of pome fruit germplasm in the historic miniatures of ancient Persia. 14-18th century Persian artists had a thing for pears, quinces and apples, and drew them very accurately.
Brainfood: Genetic diversity, Germplasm exchange, Genomic selection, New varieties, Maya agriculture, AnGR, Diverse planted forests, Vermont seeds, Wine appellation, Roots & tubers, Late blight, Nordic barley landraces
- The long-standing significance of genetic diversity in conservation. I suppose it does need to be repeated.
- Germplasm exchange is critical to conservation of biodiversity and global food security. Yes, indeed it does look like it needs to be repeated.
- From gene banks to farmer’s fields: using genomic selection to identify donors for a breeding program in rice to close the yield gap on smallholder farms. A prime example of why it should not need to be repeated.
- Large potential for crop production adaptation depends on available future varieties. 39% of global cropland could require new crop varieties to avoid yield loss from climate change by the end of the century? You don’t say. Bears repeating.
- More than Maize, Bananas, and Coffee: The Inter– and Intraspecific Diversity of Edible Plants of the Huastec Mayan Landscape Mosaics in Mexico. Looks like we don’t need to repeat it to the Maya.
- Monitoring and Progress in the Implementation of the Global Plan of Action on Animal Genetic Resources. Significant progress, but correlated with per capita GDP. So some people are listening to the endless repetition; but not enough.
- For the sake of resilience and multifunctionality, let’s diversify planted forests! Yes, it needs to be repeated for forests too.
- Motivations for maintaining crop diversity: Evidence from Vermont’s seed systems. Yes, repeat by all means, but with variation.
- How big is the “lemons” problem? Historical evidence from French wines. Quality certification schemes can support the market value of products. And of course they can be good for genetic diversity too.
- Crop resistance and household resilience – The case of cassava and sweetpotato during super-typhoon Ompong in the Philippines. Root and tuber crops are good for household resilience in typhoon-affected areas. Not exactly genetic diversity, but still bears repeating.
- Global historic pandemics caused by the FAM-1 genotype of Phytophthora infestans on six continents. Why genetic diversity is necessary for root and tuber crops too. As if it needed repeating.
- Genetic Diversity in 19th Century Barley (Hordeum vulgare) Reflects Differing Agricultural Practices and Seed Trade in Jämtland, Sweden. What causes all that genetic diversity we’ve been repeating endlessly about.
Brainfood: Plant services, Ornamental conservation, Cinnamon, Avocado, Apricot double, Apple, Date palm, Bambara groundnut, Amaranth, On farm research, Fertilizer subsidies
- A global database of plant services for humankind. 13% of over 13,000 plant genera have been recorded as human food. But twice as many are described as “ornamentals.”
- Horticultural plant use as a so-far neglected pillar of ex situ conservation. Something we can do about those ornamentals. But not only ornamentals, surely.
- “Ceylon cinnamon”: Much more than just a spice. But not, alas, an ornamental.
- Exploring genetic diversity of lowland avocado (Persea americana Mill.) as a genetic reservoir for breeding. Plus it’s a handsome tree.
- Population genomics of apricots unravels domestication history and adaptive events. Separate Chinese and European genepools, deriving from independent domestications from distinct populations. No word on which is more ornamental.
- Diversity and Relationships among Neglected Apricot (Prunus armeniaca L.) Landraces Using Morphological Traits and SSR Markers: Implications for Agro-Biodiversity Conservation. Get farmers to grow varietal mixtures for maximum ornamental value — and conservation.
- Unraveling a genetic roadmap for improved taste in the domesticated apple. No evidence of selection for increased sugar content. And ornamental value?
- Molecular clocks and archaeogenomics of a Late Period Egyptian date palm leaf reveal introgression from wild relatives and add timestamps on the domestication. Ancient hybrid origin for the coincidentally ornamentally and otherwise valuable food crop, followed by introgression from both wild close congeneric relatives.
- Genetic diversity and population structure analysis of bambara groundnut (Vigna subterrenea L) landraces using DArT SNP markers. 3 groups: W Africa, Central Africa, E + S Africa. No word on which would make the most attractive ornamentals.
- A chromosome-level Amaranthus cruentus genome assembly highlights gene family evolution and biosynthetic gene clusters that may underpin the nutritional value of this traditional crop. Yeah, but where are the genes that make it ornamental too?
- How accurate are yield estimates from crop cuts? Evidence from smallholder maize farms in Ethiopia. More accurate than estimates of horticultural attractiveness, I suspect.
- The unintended consequences of the fertilizer subsidy program on crop species diversity in Mali. Spoiler alert: they’re bad. Fortunately, ornamentals don’t attract subsidies.

- GAIN Discussion Paper 9: Food group diversity and nutrient adequacy. Eat a diverse diet…
- Can Underutilized Tropical Fruits Meet the Nutritional Requirements of Rural Indonesia? …which includes fruits, of course.
- The nutritional quality of cereals varies geospatially in Ethiopia and Malawi. And cereals, though it depends where they’re growing.
- Variation for Photoperiod and Temperature Sensitivity in the Global Mini Core Collection of Sorghum. Less than 10% are sensitive to neither. And yes, there’s another paper on the nutrient quality of the same subset. Though not on how that varies geographically.
- Habitat value of bivalve shellfish and seaweed aquaculture for fish and invertebrates: Pathways, synthesis and next steps. Eat more bivalves and seaweed too, it can be good for the environment too.
- Measurements of lethal and nonlethal inbreeding depression inform the de novo domestication of Silphium integrifolium. Always good to have a new oil crop, especially a perennial one, but careful what you cross to get it, and how.
- Genome design of hybrid potato. Re-inventing the potato as a seed-propagated crop could be good for nutrition, sure, why not.
- High Throughput can produce better decisions than high accuracy when phenotyping plant populations. As you make better and more nutritious crops, keep in mind it may be better to phenotype more plants in more environments than obsess about accuracy and precision. What does that mean for mini-cores?
- Insight into the introduction of domestic cattle and the process of Neolithization to the Spanish region Galicia by genetic evidence. But is any of this worth the hassle? After all, the early domesticated cattle of Galicia are similar to modern breeds…

- Unlocking big data doubled the accuracy in predicting the grain yield in hybrid wheat. Breeding programmes and genebanks need to pool their data. That’s kind of what the Plant Treaty’s GLIS is for, isn’t it?
- Resequencing of 672 Native Rice Accessions to Explore Genetic Diversity and Trait Associations in Vietnam. Another example of the above: an indica sub-population in Vietnam is pretty unique and seemingly untapped in breeding.
- Quantifying apple diversity: A phenomic characterization of Canada’s Apple Biodiversity Collection. And another: 20,000 apples phenotyped to within an inch of their lives to show, among many other things, that new varieties have been getting lower in phenolics.
- Towards a Joint International Database: Alignment of SSR Marker Data for European Collections of Cherry Germplasm. I swear I didn’t plan this…
- Morphological and eco-geographic diversity analysis of maize germplasm in the high altitude Andes region of Ecuador. Loja province is a bit of a maize diversity hotspot, and you don’t need big data to prove it.
- The transition to agricultural cultivation of neo-crops may fail to account for wild genetic diversity patterns: insights from the Cape Floristic Region. Taking a new species into cultivation can lead to a genetic bottleneck, and you don’t need big data to prove it.
- Fish domestication in aquaculture: 10 unanswered questions. Same as above for fish, but oddly genetic diversity doesn’t feature among the questions. Maybe the answer would have been too obvious?
- Transition From Wild to Domesticated Pearl Millet (Pennisetum glaucum) Revealed in Ceramic Temper at Three Middle Holocene Sites in Northern Mali. How wild pearl millet was taken into cultivation can be followed in time because bits of the plants were added to clay to prevent the pots cracking during firing in ancient times. The opposite of big data, but still pretty cool.
- Africa’s evolving vegetable seed sector: status, policy options and lessons from Asia. Seed companies in Africa need capacity, policies, extension, and marketing. And data, I would add.
- Are the modern-bred rice and wheat cultivars in India inefficient in zinc and iron sequestration? Eat more vegetables? Don’t need data to figure that out.
- A history of Australian pasture genetic resource collections. 85,000 accessions qualifies as pretty big. Not sure about the data though.
