- Rapid adaptive increase of amylase gene copy number in Indigenous Andeans. Indigenous Andean populations evolved exceptionally high copy numbers of the AMY1 salivary amylase gene, likely linked to long-term adaptation to starch-rich diets associated with potato domestication roughly 10,000 years ago.
- Horse genetics, archaeology, and the beginning of riding. Horse domestication was not a sudden genetic event beginning around 2200–2100 BCE, but a long and regionally varied process in which Indigenous Eurasian pastoralists progressively managed, rode, milked and selectively bred multiple horse lineages over many centuries, transforming mobility and social organization well before the rise of the dominant modern domestic horse lineage.

Brazil’s non-conventional food plants (PANCs) and associated Indigenous and traditional knowledge could help build more diverse, climate-resilient and socially inclusive food systems while strengthening biodiversity conservation, rural livelihoods and public food programs.
- Indigenous Wisdom for a Changing World: Bridging Traditional Ecological Knowledge and Biodiversity Conservation. Sacred groves and other community-managed landscapes in central Ethiopia conserve high levels of biodiversity through Indigenous institutions, ritual practices and traditional ecological knowledge, suggesting that effective conservation depends on treating cultural stewardship systems as integral to ecological resilience rather than as secondary to scientific management.

- Domesticated: How Cultivated Species Altered Ancient Silk Road Societies. Different stages of adopting and intensifying the use of domesticates (livestock, horses, and later crops) reshaped economies, mobility, and social organization in north-central Asia, ultimately enabling the emergence of the Silk Road. So domesticated species were as active drivers of Eurasian historical development as of prehistory.
- Ancient grains illuminate the mosaic origin of domesticated wheat. Domesticated wheat arose through repeated hybridizations between distinct wild populations carrying complementary non-shattering spike mutations, followed by ongoing gene flow and regional adaptation, making domestication a prolonged and interconnected process. Long before the result got to the Silk Road.
- A single hybrid origin of cultivated peanut. Domestication of the peanut seems to have been easier than that of wheat.
- A synthetic eco-evolutionary proposal for the conservation of wild relatives of the olive tree. If we ever have to re-domesticate the olive, we should make sure these 53 wild populations are conserved.

At least some Maori ate predominantly sweet potato and taro during the Traditional Period. Which of course were brought to Aotearoa via the ara moana, which, stretching a point, is the South Pacific equivalent of the Silk Road.

The seeds of tropical fodder grass development
Usually, if plant breeders do anything at all with wild species, they use them to try to improve the domesticated relative in some way. But in Bajra–Napier Hybrids (BNH), it’s actually the crop that is used to improve a wild (or at least wildish) relative.
That’s more than just a fun fact. BNH are actually pretty important forages in tropical and subtropical livestock systems, though you don’t hear too much about them other than from specialists. I certainly hadn’t, until a recent social media blitz from ICRISAT.
They are made by crossing the crop pearl millet (bajra, Pennisetum glaucum) with the related forage Napier grass (Pennisetum purpureum). This has the effect of combining nicely complementary traits into a highly productive fodder plant.
The best thing about BNH is their high yield of biomass. Under ideal conditions, annual green fodder production can exceed 200–300 tonnes per hectare, which comfortably outperforms other forage grass options. This productivity is due to fast growth, profuse tillering, and efficient nutrient uptake. For smallholder dairy systems, where land is usually at a premium, such a yield advantage translates pretty quickly into higher milk output per area. Also, BNH are perennial, which reduces costs over time, as fields can remain productive for several years with proper care.
And the nutritional profile of the fodder is pretty good. Crude protein is typically 8–14%, depending on management and cutting stage, while digestibility remains ok if the plants are harvested relatively early, before they start getting woody, say at 45–60 day intervals.
BNH are resilient, being tolerant to drought and intermittent water stress, a trait inherited largely from pearl millet, though they also respond well to irrigation and fertilization. That makes them widely suitable, everywhere from low-input rainfed systems to intensive peri-urban dairying.
All that said, there are drawbacks. Perhaps the main one is that BNH are typically sterile, not producing seeds, and therefore have to be propagated vegetatively, through stem cuttings or root splits. This means farmers depend on planting material supply chains that are often weak or informal. Diseases can also be transmitted more easily via vegetative material. Plus high biomass production demands big nutrient inputs, particularly nitrogen, with inadequate fertilization quickly eroding both yield and quality. That can be expensive.
In response, an important recent line of research has focused on developing seed-propagated BNH. Seeds simplify dissemination, reduce transport costs, and mitigate the spread of vegetatively transmitted diseases. They also enable more formal seed sector engagement, including developing new varieties.
Making fertile hybrids is technically tricky. Sterility in the classic hybrids is due to genomic incompatibilities between the parental species, basically their different ploidies, or numbers of chromosomes. So breeding strategies have explored chromosome doubling, intermediate ploidy levels, and backcrossing to restore partial fertility while retaining the desirable forage traits.
This has been reasonably successful, but trade-offs remain: some seed-propagated lines show lower biomass yields or less persistence compared to established clonal hybrids, and ensuring consistent performance across environments is still a work in progress. So it’s good to see ICRISAT and its partner still on the case, hard at work.
ICRISAT is advancing forage research with trials on seed-propagated Bajra–Napier Hybrids (BNHs) a shift from traditional stem cuttings to a scalable, seed-based approach.

LATER: Dr Chris Jones, program leader for feed and forage development at ILRI, who should know, tells me that the currently accepted names for the parents of BNH are Cenchrus americanus (pearl millet) and C. purpureus (Napier grass). Something to do with Cenchrus being nested within Pennisetum evolutionarily speaking, so the best bet was to merge the genera, but under the name Cenchrus because that is the older one.
