Four newly identified chameleons reveal the hidden diversity of Mozambique’s isolated mountain forests. Surveys of these granite mountains have now identified four previously unknown species of Sylvan Chameleons, each confined to a separate “sky island.” They sequenced four genes (DNA sequences) from Sylvan Chameleons collected on different mountains, compared the genetic patterns, and then considered those results alongside differences in body features. The Mount Namuli species, Nadzikambia franklinae, recognizes Rosalind Franklin, whose work on the structure of DNA helped establish the science behind the genetic methods used to distinguish the chameleons.
