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 ...

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 ...

A stunning new fossil find from the Grand Canyon fills in some blanks from a time when evolution began experimenting with weird new forms. Frustratingly, fossils from later in the Cambrian period are ...

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 ...

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 ...

Discover interesting facts about how evolution works, the different patterns that can emerge from evolution, how quickly organisms can evolve, and whether evolution is a random or ordered process When ...

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 ...

Sometimes, the most significant scientific discoveries happen by accident. Scientists have long known that whole-genome duplication (WGD)—the process by which organisms copy all their genetic material ...
