The finding sheds new light on early frog evolution, suggesting that even at their earliest evolutionary stages, frogs and toads had a tadpole life stage, according to John Long, a palaeontologist ...

This exceptional finding sheds light on a distant aquatic past where giant tadpoles roamed the ponds of the Jurassic, 161 million years ago. Amphibians, and particularly frogs, undergo a unique ...

These are tadpoles. They've hatched from these small ... The human life cycle is last, we see clips of the different stages in the life cycle of a human. The teacher could then ask the students ...

Millions of years ago, a 16-centimetre tadpole met an untimely end, sinking to the bottom of a pond where it would stay for millennia. Research on the Jurassic amphibian, which has today been ...

The tadpole discovered belongs to the Jurassic species Notobatrachus degiustoi, according to the published research, and provides a greater understanding of the evolution of the life cycle of a frog.

Marcks and Marcks-like 1 proteins are required for normal neurite formation and proliferation of neuro-glial progenitors during development and regeneration of the Xenopus spinal cord implicating ...

My lab studies these questions in the developing visual system of the Xenopus laevis tadpole. Because these tadpoles are transparent and their developmental stage readily identified, we are able to ...
