- Human dispersal and plant processing in the Pacific 55 000–50 000 years ago. There was more to the peopling of the Pacific than seafaring.
- Identification of breadfruit (Artocarpus altilis) and South American crops introduced during early settlement of Rapa Nui (Easter Island), as revealed through starch analysis. Though seafaring took these people all the way to South America, it sees.
- Early agriculture and crop transitions at Kakapel Rockshelter in the Lake Victoria region of eastern Africa. A bit like Rapa Nui, Lake Victoria got crops from both west and east over time.
- Cotton and post-Neolithic investment agriculture in tropical Asia and Africa, with two routes to West Africa. Funny they didn’t find cotton at the Lake Victoria site.
- Drawing diffusion patterns of Neolithic agriculture in Anatolia. Itinerant expert harvesters spread agriculture into Anatolia. Maybe around Africa too, who knows.
- Early animal management in northern Europe: multi-proxy evidence from Swifterbant, the Netherlands. Early farmers in northern Europe managed separate herds of cattle in different ways alongside crops. What, itinerant expert livestock herders too?
- Introduction, spread and selective breeding of crops: new archaeobotanical data from southern Italy in the early Middle Ages. Sicily is a bit like Rapa Nui and Lake Victoria.
- Rice’s trajectory from wild to domesticated in East Asia. Rice domestication pushed back to about the same time as the Fertile Crescent. No word on the role of expert harvesters.
- Archaeological findings show the extent of primitive characteristics of maize in South America. Maize arrived in lowland South America in a pre-domesticated state, and stayed like that for a long time. That’s a long way for expert harvesters to go.

- Benefit–Cost Analysis of Increased Funding for Agricultural Research and Development in the Global South. Fancy model says funding agricultural research is great value for money. Ok, let’s see if we can find some examples.
- Exploring CGIAR’s efforts towards achieving the Paris Agreement’s climate-change targets. Yeah, but in designing such research to mitigate climate change there should be more complete integration of food-systems perspectives.
- Crop species diversity: A key strategy for sustainable food system transformation and climate resilience. Now there’s a nice thing to integrate into your climate change adaptation and integration research.
- Cultivating success: Bridging the gaps in plant breeding training in Australia, Canada, and New Zealand. Gonna need more plant breeders also, though.
- Artificial intelligence in plant breeding. Yeah, and probably more artificial intelligence too.
- Wheat genetic resources have avoided disease pandemics, improved food security, and reduced environmental footprints: A review of historical impacts and future opportunities. Great advances have been made (even without AI) by wheat breeders, but there’s still a lot of untapped diversity out there.
- Harnessing landrace diversity empowers wheat breeding. For example in the A. E. Watkins landrace collection.
- Enhanced radiation use efficiency and grain filling rate as the main drivers of grain yield genetic gains in the CIMMYT elite spring wheat yield trial. Gotta wonder if there’s a limit though.
- Origin and evolution of the bread wheat D genome. Maybe we can squeeze a bit more out of the D genome. I wonder what AI says about that.
- The Role of Crop Wild Relatives and Landraces of Forage Legumes in Pre-Breeding as a Response to Climate Change. As above, but for a bunch of forages.
- Stakeholder Insights: A Socio-Agronomic Study on Varietal Innovation Adoption, Preferences, and Sustainability in the Arracacha Crop (Arracacia xanthorrhiza B.). Here’s an interesting methodology to evaluate the impact of new varieties designed and developed by AI (or not).
- Deep genotyping reveals specific adaptation footprints of conventional and organic farming in barley populations — an evolutionary plant breeding approach. An initial, diverse barley population is allowed to adapt to contrasting organic and conventional conditions for 2 decades and diverges considerably genetically as a result. Don’t need AI to predict that. Perhaps more surprisingly, analysis suggests organic-adapted populations need to be selected for root traits to catch up in yield.
- Natural selection drives emergent genetic homogeneity in a century-scale experiment with barley. What is it with barley breeding and long-term experiments? This one shows that a hundred years of natural selection has massively narrowed genetic diversity. Why aren’t there long-term wheat experiments? Or are there?
- Association study of crude seed protein and fat concentration in a USDA pea diversity panel. Really high protein peas are possible. No word on whether kids will like them any better. Let’s check again in a hundred years?
- Telomere-to-telomere Citrullus super-pangenome provides direction for watermelon breeding. Forget sweetness and disease resistance, maybe one of these wild species will help us grasp the holy grail of seedlessness. Wait, let me check on the whole cost-benefit thing for this.
- An indigenous germplasm of Brassica rapa var. yellow NRCPB rapa 8 enhanced resynthesis of Brassica juncea without in vitro intervention. Sort of like that wheat D genome thing, but for mustard. I do wonder why we don’t try crop re-synthesis a lot more.
- Special issue: Tropical roots, tubers and bananas: New breeding tools and methods to meet consumer preferences. Why involving farmers in all of the above could be a good idea.

- Global spatially explicit yield gap time trends reveal regions at risk of future crop yield stagnation. For 8 of 10 major crops, yield gaps have widened steadily from 1975 to 2010 over most areas, and remained static for sugar cane and oil palm. Time to turbo-charge the breeding?
- Domestication and the evolution of crops: variable syndromes, complex genetic architectures, and ecological entanglements. If you want to turbo-charge breeding, you need to understand (among other things) the ecological context of domestication.
- Including Traditional Ecological Knowledge (TEK) in Agricultural Research: Guidelines and Lessons Learned. I suspect Traditional Ecological Knowledge can help with figuring out the ecological context of domestication.
- High levels of genetic variation and differentiation in wild tropical gourds provide a novel resource for cucurbit crop improvement. Ok, but ecological knowledge would like a word.
- Understanding genetic diversity in drought-adaptive hybrid parental lines in pearl millet. Any link to ecology of original collecting sites, I wonder?
- Genetic Diversity and Population Structure Analysis of a Diverse Panel of Pea (Pisum sativum). Again, ecological knowledge conspicuous by its absence. Maybe the passport data just weren’t up to it?
- Banana seed exchange networks in Burundi – Linking formal and informal systems. Yes, yes, it’s not just about the breeding, the seed system also has to work.
- Editorial: Current status of honey bee genetic and breeding programs: progress and perspectives. Pollinators need breeding programmes too.
Brainfood: Archaeology edition
- Early human selection of crops’ wild progenitors explains the acquisitive physiology of modern cultivars. The high leaf nitrogen, photosynthesis, conductance and transpiration of crops was already there in their wild relatives, the first farmers just happened to domesticate greedy plants.
- The impact of farming on prehistoric culinary practices throughout Northern Europe. When the first farmers arrived in northern Europe armed with their greedy plants, they learned a lot about food from the local hunter-fisher-gatherers, and vice-versa, but without much interbreeding. Jeremy interviews one of the authors on his podcast.
- Early contact between late farming and pastoralist societies in southeastern Europe. There was extensive interbreeding between farmers and the local transitional foragers/herders before with the expansion of pastoralist groups into Europe from the Eurasian steppes around 3300 BC.
- Isotopes prove advanced, integral crop production, and stockbreeding strategies nourished Trypillia mega-populations. The earliest European mega-settlements, in Ukraine and Moldova, from around 4000 BCE, integrated greedy crops and generous domesticated livestock.
- Inference of Admixture Origins in Indigenous African Cattle. Following introduction from the Near East, domesticated cattle got admixed with a North African extinct aurochs before spreading throughout Africa.
- Flax for seed or fibre use? Flax capsules from ancient Egyptian sites (3rd millennium BC to second century AD) compared with modern flax genebank accessions. Fibre first.
- Revealing the secrets of a 2900-year-old clay brick, discovering a time capsule of ancient DNA. DNA from 34 plant groups were detected inside an old brick when it happened to break.
- Making wine in earthenware vessels: a comparative approach to Roman vinification. Comparison with modern counterparts shows that Roman clay jars for storing wine were integral to the process. No word on whether there was any ancient DNA in the clay.
- Breadfruit in the Pacific Islands, its domestication and origins of cultivars grown in East Polynesia and Micronesia. Spoiler alert: they came from Polynesian Outlier Islands.

- A sustainable blue cheese industry needs more microbial diversity.
- The Open Source Seed Initiative gets written up in The Guardian. Looks like we need something similar for cheese microbes.
- The Guardian then follows up with mung bean breeding and fart jokes.
- But then goes all serious with talk of trillions of dollars in benefits from sustainable food systems. Diversity not mentioned, alas, though, so one wonders about the point of the previous pieces.
- Fortunately Indigeneous Colombian farmers have the right idea about sustainability.
- Collard greens breeders do too, for that matter.
- More African native crops hype for Dr Wood to object to. Seriously though, some crops do need more research, if only so they can be grown somewhere else.
- There’s plenty of research — and art for that matter — on the olive, but the international genebanks could do with more recognition.
- The mezcal agave, on the other hand, doesn’t seem to have much diversity in genebanks, and it is threatened in the wild.
- Perry culture in Germany is also threatened. Pretty sure there are genebanks though.
- This piece about tomato diversity in Spain is worth reading for many reasons (heroic seed saving yada yada), but especially for the deadpan take on the Guardia Civil at the end.
- Maybe we could breed some of those tomatoes to fix their own nitrogen. And get the Guardia Civil to pay for it.
