- The genetic identity of the earliest human-made hybrid animals, the kungas of Syro-Mesopotamia. According to 4500 year old DNA, these super-donkeys were sterile crosses between female domestic donkeys and wild male asses. I guarantee nothing below will be as much fun as this.
- Haplotype analyses reveal novel insights into tomato history and domestication driven by long-distance migrations and latitudinal adaptations. I was wrong. Turns out tomatoes came about by one wild species evolving into a semi-domesticated one during a gradual migration from the Peruvian deserts to the Mexican rainforests and that fully domesticated Peruvian and Ecuadorian populations were the result of more recent back-migrations.
- Semi-natural habitats promote winter survival of wild-living honeybees in an agricultural landscape. Wrong again. Rare wild honeybees have been found in Galician power poles.
- High-resolution association mapping with libraries of immortalized lines from ancestral landraces. Actually, immortal landraces sound pretty cool too.
- From cultivar mixtures to allelic mixtures: opposite effects of allelic richness between genotypes and genotype richness in wheat. Mixtures of inbred lines are generally better than pure stands for coping with blotch disease, but sometimes specific allelic combinations undermine this. Well, ancient super-donkeys it ain’t, but still.
- Local communities’ perceptions of wild edible plant and mushroom change: A systematic review. The literature shows that local people are worried about the decreased abundance of the wild plants they rely on for food and nutrition security.
- Weeds Enhance Pollinator Diversity and Fruit Yield in Mango. That should be “weeds.” They’re not weeds if they’re actually useful. Maybe some of them are even edible.
- Multilateral benefit-sharing from digital sequence information will support both science and biodiversity conservation. We need a multilateral DSI benefit-sharing system which decouples access to DSI from sharing the benefits of DSI use. Where have I heard that before? And can I hear more about ancient hybrid super-donkeys instead?
- Diversity of Fusarium associated banana wilt in northern Viet Nam. The dreaded TR4 is still rare, but the pathogen lurks among the wild species too.

The real dope on dope
If you were not satisfied with my glib summary of the paper “Large-scale whole-genome resequencing unravels the domestication history of Cannabis sativa” last August, the indefatigable Dorian Fuller has you covered.
Bottom line: incomplete sampling and imprecise dating mean that multiple domestications of the crop in China at the same time as, or even after, those of millets should not be ruled out just yet.
A juicy tomato story
Jeremy’s latest newsletter has a useful snippet on a paper on the history of the tomato in Europe. I’ll reproduce it below as a taster, but consider subscribing, as there’s lots of other interesting stuff too, on everything from pizza to chocolate.
Maybe you saw those beautiful illustrations of 16th century tomatoes that were doing the rounds a few days ago. They were prompted by a lovely paper from the Netherlands looking at the earliest tomatoes in Europe. The paper may be a bit heavy going, but the researchers published their own summary for the rest of us.
The paper sheds light on those first tomatoes to arrive, and in particular on the notion that these first fruits “were elongated, segmented, and gold in color. After all, that is how they were depicted, and they were called ‘pomo d’oro’: golden apple.” Herbarium specimens and old drawings, many of them newly digitised, revealed many different colours, shapes, and sizes, but not whether tomatoes originated in Peru or Mexico, the two leading candidates. The Dutch researchers sequenced the highly degraded DNA of their specimen and say that it was definitely not a wild plant, and shows strong similarities with three Mexican varieties and two from Peru.
The indigenous Andes population in Peru started domesticating a small wild cherry tomato. They brought this to Mexico, and there they developed the tomato with large fruit that we know today.
No herbarium specimen is ever likely to germinate, so to find out how these first tomatoes in Europe might have tasted the best bet, they suggest, is to go to Mexico and Peru. DNA analysis could probably indicate the closest known relatives for a taste test.
Now, will someone please examine critically the whole “tomatoes didn’t catch on because they were considered poisonous” thing, or is there already enough proof of that?
