    How one lizard thrives on top of the world

    No lizard lives at higher altitudes than P.erythrurus, which makes it home high on the Tibetan plateau; new research provides insights into the genetic changes this species has undergone to adapt to life in such a challenging environment.

    Sex in butterflies is a curious thing

    Closely related wood white butterfly species substantially differ in chromosome number and structure including, remarkably, possession of unique sex chromosome constitutions in each species, supporting an important role for chromosome rearrangements in speciation.
