The discovery is helping to clear up a long-standing mystery as to when frogs and toads evolved their iconic two-stage life-cycle. "The research demonstrates that a tadpole stage followed by a ...

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 ...

Because these tadpoles are transparent and their developmental stage readily identified, we are able to image and record the electrical activity in individual neurons at different stages in circuit ...

This lack of evidence had suggested that older frog species, especially those from the Jurassic, did not go through a larval stage. However, the recent discovery of a tadpole fossil contradicts this ...

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.

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 ...

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 ...
