Evolution and development of facial bone morphology in threespine sticklebacks.
How do developmental mechanisms evolve to control changing skeletal morphology, the shapes and sizes of individual bones? We address this question with studies of the opercle (OP), a large facial bone that has undergone marked morphological evolution in the ray-finned fish. Attributes for developmental analysis motivated us to examine how OP shape and size evolve and develop in threespine stick...
متن کاملFishing for the secrets of vertebrate evolution in threespine sticklebacks.
The threespine stickleback (Gasterosteus aculeatus) is rapidly emerging as a new model genetic system to study questions at the interface of evolution and development. The relatively rapid and recent diversification of this small teleost fish, combined with the development of genetic and genomic tools for this fish, provides an unprecedented opportunity to identify the genetic and molecular bas...

15 صفحه اولGenetic and Neural Modularity Underlie the Evolution of Schooling Behavior in Threespine Sticklebacks
Although descriptions of striking diversity in animal behavior are plentiful, little is known about the mechanisms by which behaviors change and evolve between groups. To fully understand behavioral evolution, it will be necessary to identify the genetic mechanisms that mediate behavioral change in a natural context. Genetic analysis of behavior can also reveal associations between behavior and...
متن کاملEvolution of Schooling Behavior in Threespine Sticklebacks Is Shaped by the Eda Gene.
Despite longstanding interest in the genetic mechanisms that underlie behavioral evolution, very few genes that underlie naturally occurring variation in behavior between individuals or species are known, particularly in vertebrates. Here, we build on our previous forward genetic mapping experiments and use transgenic approaches to identify Ectodysplasin as a gene that causes differences in sch...
