Lineage fusion in G alápagos giant tortoises

RC Garrick, E Benavides, MA Russello… - Molecular …, 2014 - Wiley Online Library
Although many classic radiations on islands are thought to be the result of repeated lineage
splitting, the role of past fusion is rarely known because during these events, purebreds are …

Self-righting potential and the evolution of shell shape in Galápagos tortoises

Y Chiari, A van Der Meijden, A Caccone, J Claude… - Scientific Reports, 2017 - nature.com
Self-righting, the capacity of an animal to self-turn after falling on its back, is a fitness-related
trait. Delayed self-righting can result in loss of mating opportunities or death. Traits involved …
