The sticky fruit of the date palm has a tangled history. New research in G3 explores the palm’s genetic diversity and traces its earliest cultivation to at least two distinct regions in North Africa and the Arabian Gulf. The date palm (Phoenix dactylifera) is one of the world’s oldest cultivated trees and has close ties…

If not for a single-nucleotide mutation, each kernel on a juicy corn cob would be trapped inside an inedible casing as tough as a walnut shell. In the July issue of GENETICS, Wang et al. identify an amino acid substitution that was key to the development of the so-called “naked” kernels that characterize modern corn…

Laboratory zebrafish hide a dirty little secret. Although the tiny fish have proven to be a vital model of vertebrate development and disease genetics, zebrafish reproduction—at least in the lab—has wildly variable outcomes. Offspring sex ratios can vary from extremely male-biased to extremely female-biased, depending on which breeding pairs serve as parents. The reason for…

In the early 1970s, a couple of hundred wild rats near the Siberian city of Novosibirsk were rounded up by scientists for an ambitious experiment to understand how animals evolve during domestication. Dimitry Belyaev and his colleagues—known for their related project on domesticating foxes—split the rats into two groups. With one group, the researchers tried to replicate…

Mammal domestication is a hot topic, with many groups releasing detailed genetic studies of different models of domestication. This week we’ll look at the genetics of cat colors and follow up on the recently published domestication syndrome hypothesis. Next week we’ll feature new research on experimental rat domestication. Stay tuned! Does your cat have a…

In Stellenbosch, South Africa, in the shade of the university botanical gardens, Adam Wilkins and Richard Wrangham drank coffee and worked their way through a list. Tameness. Smaller muzzles. Smaller teeth. Patches of white fur. Floppy ears. In early 2011, Wilkins, Perspectives editor at GENETICS, and Wrangham, primatologist at Harvard, were both spending the semester…
