Cracking the egg

er organisms previously studied, a frog and a sea squirt. Obviously early development is a very stable process and many of the crucial steps associated with it have remained the same along the vertebrate evolutionary pathway. But at the same time there's evidence of instability in other areas.

According to Dr. Evsikov, "There's tantalizing evidence for rapid change in a few critical mammalian genes specifically expressed in eggs. These fast-paced changes may pinpoint the molecular mechanisms for reproductive isolation, a primary cause for the origin of new species, and an astonishing diversity of mammals inhabiting Earth."
