Through studies of these bugs, whose bodies match the leaves the insects live on, researchers have found that although groups of the bug have
evolved similar appearances, they achieved that mostly via different changes in their DNA.
«Environmental changes would have produced a lot more fragmented, mosaic - type ecosystems, where populations of horses with
similar demands and adaptations could have
evolved isolated from one another, resulting in different species but with a
similar appearance,» points Manuel Hernández Fernández at the Complutense Univerity in Madrid.
