- 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.
Canaries in the genetic coal mine
Specialism in science being what it is, it’s understandably unusual to see papers which combine combine analysis of genetic diversity in humans over time with that of crops, or indeed livestock. It’s less understandable why it should also be unusual in science journalism, and examples should be celebrated. So hats off to Warren Cornwall for his very readable synthesis in Science of the history of human and crop genetic diversity in the Canaries over the past two thousand years. Well worth a read.

- A self-described seed mixologist calls for a science fiction, rather than historical, approach to growing heirloom varieties. Excellent reading.
- The Renaissance approach to genetic mixology explained in a new book The Perfection of Nature.
- Sometimes, though, you just want a good old watermelon.
- Or a good old apple.
- Or indeed ‘the Swiss army knife of equines.’
- Or you want to know what ancient people ate and drank.
- So it’s a good thing we have genebanks, genebanks, genebanks…
