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 ...

Humans have unwittingly been carrying out evolution experiments for millennia through the domestication of plants, animals, and fungi. Starting with the seminal experiments of William Dallinger in the ...

Over 3,000 generations of laboratory evolution, researchers watched as their model organism, 'snowflake yeast,' began to adapt as multicellular individuals. In new research, the team shows how ...

"Why and how did life become so diverse? This has been a central problem in biology. Experimen-tal Evolution and the Nature of Biodiversity explores how diversity evolves in microbial popula-tions ...

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 ...
