Frogs prove ideal models for studying developmental timing

Thyroid hormone receptor alpha plays an important role in hind limb development in frogs, scientists have found. With new gene mutation technology, researchers were able to successfully mutate the gene in the tadpole models, discovering the value of tadpoles as ideal models for studying the role of hormones in development because of the timely metamorphosis from tadpole to juvenile frog, and because that transition is completely dependent on hormones.
