Scientists have developed a theoretical model that uncovers the dual role of polyploidy -- organisms carrying extra genome copies -- in evolution. Their findings reveal that polyploidy can stabilize ...
In 1859, Darwin imagined evolution as a slow, gradual progress, with species accumulating small changes over time. But even he was surprised to find the fossil record offered no missing links: the ...
Findings suggest that new genes can form by repurposing fragments of ancestral genes while incorporating entirely new coding regions (the protein-coding parts of the DNA). This innovative concept ...
A new study by researchers at the Max Planck Institute for Evolutionary Biology (MPI-EB) sheds fresh light on one of the most debated concepts in biology: evolvability. The work provides the first ...
Developmental biology has come of age / Donald D. Brown -- Expression and developmental regulation of the maize Spm transposable element / J.A. Banks, P. Masson and N.V. Fedoroff -- Chicken antibody ...
Researchers at the Technion have discovered how changes in genetic regulatory sequences can lead to alterations in the form and structure of animals—even when genetic regulatory systems are stable and ...

Ironically, one great unsolved problem in Darwin's master work, On the Origin of Species, was just that: How and why do species originate? Darwin and his later followers were faced with a seeming ...
