Finding the Actions That Alter Evolution
...while the existing framework of evolutionary theory, known as the “modern synthesis,” is basically solid, it needs to be expanded to account for newly recognized drivers of evolution. One such...
Theorists Debate How ‘Neutral’ Evolution Really Is
...been confirmed very well,” said Jianzhi Zhang, who studies the evolution of genomes at the University of Michigan and also contributed to the special issue of Molecular Biology and Evolution....
Three Biochemists Win Chemistry Nobel for Directing Evolution
...they have been able to make evolution many thousand times faster, and they have also been able to direct evolution to create proteins with new and useful properties.” According to...
The New Quest to Control Evolution
Modern scientists aren’t content with predicting how life evolves. They want to shape it. Evolution is a complicated thing. Much of modern evolutionary biology seeks to reconcile the seeming randomness...
Mollusk Eyes Reveal How Future Evolution Depends on the Past
The visual systems of an obscure group of mollusks provide a rare natural example of path-dependent evolution, in which a critical fork in the creatures’ past determined their evolutionary futures....
Interspecies Hybrids Play a Vital Role in Evolution
...an evolutionary biologist at Harvard University. Today, he added, saying that such hybridizations don’t affect reconstructions of evolutionary history or “that this wasn’t useful in adaptive evolution — that’s no...
Evolution: Fast or Slow? Lizards Help Resolve a Paradox.
...paradox of stasis.” Evolution’s Steady Hand? When early evolutionary theorists conceived of natural selection, they reckoned that the evolutionary process works gradually over vast epochs. Species don’t evolve overnight; they...
Mathematical Simplicity May Drive Evolution’s Speed
Computer scientists are looking to evolutionary biology for inspiration in the search for optimal solutions among astronomically huge sets of possibilities. Creationists love to insist that evolution had to assemble...
Secrets of Early Animal Evolution Revealed by Chromosome ‘Tectonics’
...a broader picture of chromosome evolution across the tree of life,” said Paulyn Cartwright, a professor of ecology and evolutionary biology at the University of Kansas. Now, she said, scientists...
