The paper tests for positive selection in centromere-associated kinetochore proteins across diverse animal groups but finds sporadic positive selection in some proteins.

The paper investigates how a shared gene, doublesex, regulates distinct mimicry polymorphisms in two closely related butterfly species through different developmental mechanisms.

The paper shows that the Papilio alphenor supergene evolved through the recruitment of six new cis-regulatory elements that enable allele-specific dsx expression.
