A close-up of a male green anole lizard (photo 1). Note the lizard's toe pads. Over just 20 generations in 15 years the green anoles evolved larger toe pads equipped with more sticky scales to allow for better climbing (photo 2). The change came after the invasive brown anoles (photo 3) forced them from their ground-level habitat into the trees in order to survive.

Herpetologist Conrad Hoskin holds a new species of leaf-tailed gecko shortly after his discovery in the pockets of rainforest in the boulder fields of the Cape Melville Range (photos 1, 2). Earlier expeditions to the mountains’ base had uncovered new species, but the rough terrain had discouraged exploration of the mountains themselves. Transport via helicopter can be both dangerous and difficult.
