Artificial Selection for Paedomorphosis in the Salamander Ambystoma Talpoideum.


Heterochronic ontogenetic mechanisms such as paedomorphosis are potentially important mechanisms of both microevolutionary and macroevolutionary change. The salamander Ambystoma talpoideum is facultatively paedomorphic. Expression of paedomorphosis in this species varies among local natural populations. Two breeding lines, one from a population associated… (More)
