| | Fission in the Evolution of a Lizard Karyotype Abstract |
| | Among the species of the monticola group Anolis chrislophei has a large dewlap and uniform squamation and lacks a bold body pattern, all characters suggesting that it is the most primitive species of the group (13); A. christophei again has the 2n = 36 karyotype. | | | Anolis monticola has a reduced dewlap, non-uniform squamation, and a bold ocellate body pattern. | | | Since the higher chromosome number is the derived condition, this is a case of karyotypic change by centric fission. |
