Episode 121: Stickle-back to the future: experimental evolution in nature (with Alison Derry and Andrew Hendry)
Bibliographic record
Abstract
Can we study evolution in the wild? Are some species “super-evolvers”? On the episode, we talk with Alison Derry, a professor of biology at the University of Quebec in Montreal, and Andrew Hendry, a professor in the Department of Biology at McGill University, Canada. This episode is the second we’ve done on the team’s work, and Andrew was also a guest on our first episode in the series. This conversation was recorded live in front of an audience at Kenai Peninsula College, in Soldotna, Alaska. The college is just a few miles from the lakes where Alison, Andrew, and many of their colleagues and students carry out experiments on threespine sticklebacks. We ask Alison and Andrew about their research on the rapid evolution of these fish, which were recently reintroduced to the lakes, and how the introduction of two distinct stickleback ecotypes are affecting the evolution of zooplankton in the lakes. We also discuss the central position of sticklebacks in the food web and how the sticklebacks are impacting the ecosystems now as well as how they likely impacted the lakes in the evolutionary past.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
