- Global dispersal and adaptive evolution of domestic cattle: a genomic perspective. The scope of adaptation is pretty amazing, and has been aided by introgression from wild relatives.
- The genomic natural history of the aurochs. Which is just as well because the initial diversity of the domesticate was probably rather limited, at least in Europe.
- The Population History of Domestic Sheep Revealed by Paleogenomes. Early domesticated sheep genomes were pretty dynamic too, sometimes in parallel with shepherds and sometimes not.
- Late pre-Hispanic fog oasis settlements and long-term human occupation on the Peruvian central coast from satellite imagery. No cattle or sheep in pre-Hispanic lomas, but plenty of camelids and crops.
- American sweet potato and Asia-Pacific crop experimentation during early colonisation of temperate-climate Aotearoa/New Zealand. One of those crops was in Aotearoa by the 14th century, which is amazing.
- Musa species in mainland Southeast Asia: From wild to domesticate. Even the very wild species are affected by human use.
- Landscape genomics reveals genetic signals of environmental adaptation of African wild eggplants. Environment is not the main driver of selection, but still pretty important and thus useful in breeding. Kinda like cattle?
- Current status of global conservation and characterisation of wild and cultivated Brassicaceae genetic resources. Gotta conserve those wild relatives probably though, if they are to be used.
- Genome-wide assessment of genetic variation and population structure in cultivated vanilla from Madagascar. The results of a breeding programme 80 years ago involving wild relatives can be seen in the current structure of diversity.
Brainfood: Heraclitus, Cocoyam, Pollen, Dry chain, DSI, Global Biodiversity Framework
- Will a plant germplasm accession conserved in a genebank change genetically over time? Sure, change is inevitable, but it can be minimized, and some can be accepted.
- Cocoyam (Xanthosoma sagittifolium (L.) Schott) genetic resources and breeding: a review of 50 years of research efforts. Conventional breeding, based on inducing flowering, is possible, but will require more international exchange of germplasm. I hope someone is saving the seeds.
- Pollen banking is a critical need for conserving plant diversity. Even if it changes genetically over time.
- Applications of dry chain technology to maintain high seed viability in tropical climates. You’ve got to dry your seeds fast and hard. Probably your pollen too, come to that.
- Harmonize rules for digital sequence information benefit-sharing across UN frameworks. The big question is, should there be a single trigger point for monetary benefits, or separate ones for each treaty? At least the sequences do not change over time. But what about if the accessions from which they are derived do?
- Involving citizens in monitoring the Kunming–Montreal Global Biodiversity Framework. Yes, let’s get citizens to help us monitor all that change.
Brainfood: Beverage edition
- Crop-to-wild gene flow in wild coffee species: the case of Coffea canephora in the Democratic Republic of the Congo. DNA bits diagnostic of domesticated coffee are finding their way into wild rainforest populations, but not all that much.
- The genome and population genomics of allopolyploid Coffea arabica reveal the diversification history of modern coffee cultivars. Diversity was already pretty low in pre-domestication wild arabica, and continued going downhill after that. Time to re-synthesize the crop, I say.
- Beyond the Orthodoxy: An Overview of the Potential of ‘Other’ Coffee Species for Crop Use and their Associated Challenges. All well and good, but don’t forget there’s more to coffee than just arabica and robusta.
- Advancing Coffee Genetic Resource Conservation and Exchange: Global Perspectives and Strategies from the ICC 2024 Satellite Workshop. Time to properly secure all coffee diversity in genebanks, and that includes sorting out ABS.
- Expanding the cacao group: three new species of Theobroma sect. Herrania (Malvaceae: Byttnerioideae) from the Western Amazon Basin. Plenty of “other” cacao species too, and more coming.
- Seed morphometrics unravels the evolutionary history of grapevine in France. There was wild-domesticate geneflow in early grapevines in France as well as in robusta coffee in the DRC, and you don’t need to trace bits of DNA to prove it.
- Characterization and analysis of a Commiphora species germinated from an ancient seed suggests a possible connection to a species mentioned in the Bible. Thousand-year-old seed is a distinct and possibly long-lost species of myrrh. Which ok is not a beverage but still vaguely liquid, at least initially.
- Sesame, an Underutilized Oil Seed Crop: Breeding Achievements and Future Challenges. Ok, since we’re doing liquid-producing crops, let’s include this review of sesame improvement. Lots of wild species to use. No word on wild-domesticate geneflow though.
Nibbles: Svalbard Global Seed Vault, CePaCT genebank, CIAT genebank, Australia rice genebank, Bangladesh genebank, Maize mutants garden, Inoculants genebank, Millets community seedbank, Payments for Agrobiodiversity Conservation Services, Triadic Comparison of Technology Options, Crop diversity, Intercropping, Agroforestry, Diet diversity, World economy, Sustainable food
- Never thought I’d see the Svalbard Global Seed Vault in Psychology Today, yet here we are.
- The Pacific’s regional genebank is set for more work on lesser-known crops. Too bad most of them won’t be able to go to Svalbard.
- How to make a genebank beautiful as well as sustainable.
- Australia has a rice genebank. For some reason.
- Bangladesh gets a new genebank. Could have sworn it already had one.
- Mutants need a genebank too.
- And inoculants.
- Community-level genebanks have their place too. Though probably not for mutants.
- As long as the farmers get a benefit, of course.
- Tricot is a good way of evaluating all that stuff in genebanks.
- But you should also genotype it.
- Why bother with all this? Andreas Volz has a nice explanation.
- Genetic diversity is all very good, but don’t forget to intercrop.
- Which includes agroforestry.
- For a more varied diet.
- And a better world economy.
- And a more sustainable food system.

- 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.
