An unexpected mechanism allows wasps to rapidly co-opt genes for new toxic functions.
A definitive explanation for why plants evolved spines remains elusive, and human biases compound the problem.

Spiders appear to offload cognitive tasks to their webs, making them one of a number of species with a mind that isn’t fully confined within the head.
Answering three questions can help reveal how the “inheritance of acquired characteristics” fits into modern evolutionary theory.
