A duplicated gene evolved into a switch that determines sex in frogs, revealing how evolution can safely reshape critical ...

Researchers studied an error mechanism in DNA replication, and noticed that some errors create palindromes that can fold into hairpin structures. The complexity of ...

A gene that helped one species split into two species shows evidence of adapting much faster than other genes in the genome, raising questions about what is driving its rapid evolution. The paper in ...

The complexity of living organisms is encoded within their genes, but where do these genes come from? Researchers resolved outstanding questions regarding the origin of small regulatory genes, and ...
