Evolution is tinkering. Even at the gene level, you see that the Pax-6 gene belongs to the Pax gene family, and when you look at this gene family you can see that there are nine Pax genes known in ...

Gene duplication is very important for the evolution of species because it can facilitate the creation of new genes. Normally, changes to genes result in loss of function and so are weeded out by ...

This study provides a valuable new resource to investigate the molecular basis of the particular features characterizing the pipefish embryo. The authors found both unique and shared gene expression ...

Esvelt’s system, dubbed phage-assisted continuous evolution, or PACE, allowed scientists to hit fast forward, evolving a protein with a specific function in as little as a week. 1 The PACE system has ...

With more than 50,000 described species, the leaf beetle family is distributed ... Both symbiosis and horizontal gene transfer have strongly influenced the evolution of insects," says Roy Kirsch.

Srivastava noted that studying this rearrangement can provide important insights about the role of this gene cluster in echinoderms. “Hox genes seem to have a lot of constraint across evolution,” said ...
