In the absence of genetic variation, asexual invasive species find new methods of adapting to their environment

Without the benefits of evolutionary genetic variation that accompany meiotic reproduction, how does an asexual invasive species adapt over time to a new environment to survive? In all-female weevil species that produce only female offspring from unfertilized eggs, the insects' survival techniques have led to the surprising discovery that these creatures can pass down gene regulation changes to future generations.
