Steve Arnold visits the lizard lab Published on May 4, 2015 by Joel McGlothlin I recently hosted evolutionary biologist Steve Arnold, who happens to be my academic grandpa, as part of VT’s EEB seminar series. Steve was kind enough to share these pictures he took in our Anolis breeding colony. The lizard lab in full breeding mode. A large and a small male Anolis sagrei from two different Bahamian populations. Photos by Steve Arnold.
