Evolution: Different paths to the same end
Antonis Rokas
Abstract
Genetic dissection of a yeast gene-regulatory pathway shows that the logical output of such a pathway can remain the same even though the molecular mechanisms underlying the output have diverged remarkably.
From penguins to mushrooms and baobabs, the world around us harbours a bewildering diversity of life forms. Much of the evolution of this diversity is due to changes in the under-lying genetic regulatory architecture1.
