The Beaufort Sea (north of Alaska, northwest Canada) has iced over, with less than five percent of the basin remaining as open water as of November 11. Compare that to the 1980s and 90s, when it wasn't uncommon for "ice over" to happen in September. Data courtesy NSIDC. #akwx #Arctic #SeaIce

Using Sex-Specific Robertson Covariances to Estimate Within- and Cross-Sex Responses to Selection on Reproductive Traits in Drosophila melanogaster | The American Naturalist
Abstract In organisms with separate sexes, the expected evolutionary change in a trait due to selection can be expressed using sex-specific Robertson covariances (RCs), that is, the additive genetic c...

New paper by PhD student Aly Van Natto! 🌾🧪
Ever wondered if a plant's early start (seed vs. clonal fragment) affects the rest of their life's trajectory? We did! So we tested it over 3 yrs. Seedlings grow & flower fast but die young, while clones play the long game

In 2018, Charles Murray challenged me to a bet: "We will understand IQ genetically—I think most of the picture will have been filled in by 2025—there will still be blanks—but we’ll know basically what’s going on." It's now 2025, and I claim a win. I write about it in The Atlantic.
Your Genes Are Simply Not Enough to Explain How Smart You Are
Seven years ago, I took a bet with Charles Murray about whether we’d basically understand the genetics of intelligence by now.

Using long-term data on house sparrows, we find that quantity-quality tradeoffs near a local fitness ridge favor more or less canalized clutch size distributions in response to environmental variability.
