Expressly unfit for the laboratory

Berkeley Lab researchers found that most bacterial genes are regulated by signals unrelated to their function, leading to maladaptive regulation in laboratory settings. Only a small percentage of genes showed adaptive regulation, suggesting that natural responses may not fit the classical all-benefit-and-no-cost model.

Snail genetic tracks reveal ancient human migration
