Long-term dynamics of evolution may take around a million years

In research that will help address a long-running debate and apparent contradiction between short- and long-term evolutionary change, scientists have discovered that although evolution is a constant and sometimes rapid process, the changes that hit and stick tend to take a long time.

New fertilized cells narrowly avoid degenerating into fatal chaos

Research based at Princeton University has revealed that newly fertilized cells only narrowly avoid degenerating into fatal chaos. At the same time, scientists have discovered that embryos have acquired a mechanism to contain this dangerous instability, a finding that could help biologists unravel other mysteries about the first hours of life.

Flatworms provide new insight into organ regeneration, evolution of mammalian kidneys

Our bodies are perfectly capable of renewing billions of cells every day but fail miserably when it comes to replacing damaged organs such as kidneys. Using the flatworm Schmidtea mediterranea-famous for its capacity to regrow complete animals from minuscule flecks of tissue-as an eloquent example, researchers at the Stowers Institute for Medical Research demonstrated how our distant evolutionary cousins regenerate their excretory systems from scratch.
