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

We analysed 60 years of data on 83,000+ great tits to show how extreme climate impacts on nestling growth and survival are stage-specific and context-dependent 🐣 🌍🔥❄️

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.

Today was daily transfer 12,301. With ~6.6 generations per day, they are now at ~82,007 generations.
100,000 generations is fast approaching! Are you ready, #Spartans?
