Ancient evidence suggests a new twist in how we all got here.

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 ...

Every organism alive on Earth, from oak trees to octopuses to the bacteria in our gut, belongs to a single extended family. Genetic evidence points back to one ancestral cell, a last common forebear ...

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 ...

Genetic research does not always produce tidy answers. Sometimes it reveals traces that raise more questions than they settle ...

A genome-wide analysis has identified genetic variants that have different effects on human growth and metabolic traits depending on their parental origin. Often, the same variant will push traits in ...

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