The Amgen Scholars Program at Duke is an intensive 10-week research experience for undergraduates interested in biotechnology and drug discovery. Scholars select a faculty mentor conducting world-class drug discovery research from 15+ departments including Pharmacology & Cancer Biology, Cell Biology, Biochemistry, Chemistry, and Biomedical Engineering.
Dr. Manuel Leal and collegueas from Duke University studied how the Puerto Rican lizard (Anolis cristatellus) has adapted to the weather in Florida. They estimated that it took approximately 35 evolutive generations to adjust to colder temperatures.
ScienceDaily (Nov. 26, 2012) — One tropical lizard's tolerance to cold is stiffer than scientists had suspected. A new study shows that the Puerto Rican lizard Anolis cristatellus has adapted to the cooler winters of Miami. The results also suggest that this lizard may be able to tolerate temperature variations caused by climate change.
The Puerto Rican lizard, "Anolis cristatellus", has two populations, one living in dry forests (Guánica, Aguirre, Boquerón and Ceiba) and one living in humid forests (Guajataca, Cambalache, La Vega and Mata de Plátano). Those living in dry forests are reaching their maximum temperature and could be a victim of climate change.

A Caribbean lizard, a hurricane and a group of scientists that includes a Puerto Rican professor got "together" to help answer one of evolution's most fundamental questions.
