As a Ph.D. student, I wanted to understand the evolution of individual differences in fruit fly behavior—the building blocks ...

Scientists have watched an animal species evolve right in front of them in a fascinating 30-year-long experiment. The rough periwinkle (Littorina saxatilis) is a small species of sea snail that is ...

Darwin's other mistake / Michael R. Rose and Theodore Garland Jr. -- The importance of experimental studies in evolutionary biology / Douglas J. Futuyma and Albert F. Bennett -- Modeling experimental ...

A simple change in species composition can impact the course of evolution: A research team from the University of Bern and the University of British Columbia in Canada shows that the presence of just ...

Evolved macroscopic "snowflake" yeast from the MuLTEE experiment. The large size of the nuclei (yellow) and cells (cyan) are results of whole-genome duplication and aneuploidy. Sometimes, the most ...

How do cells know what they should become as the body develops? Biological development depends crucially on spatial patterns: the lines that eventually give rise to segments, organs, or markings like ...

When a cell divides, the genome has to be duplicated, then the two copies separate, with one going to each daughter cell. But there have been whole genome duplication events in organisms in which both ...

Scientists uncovered how whole-genome duplication emerges and remains stable over thousands of generations of evolution in the lab. Sometimes, the most significant scientific discoveries happen by ...
