The three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary relationships in the tree of life, according to a study in Nature Communications.

Two fundamental mechanisms of gene regulation involve transcription factors and microRNAs, a large class of small, non-coding RNAs. It is widely believed that phenotypic evolution is closely ...

The origins of life on Earth have long fascinated scientists, particularly the nature of the last universal common ancestor ...

A simplified evolutionary tree for the genus Psilocybe. Clade I and Clade II represent the Psilocybe species with the same gene order patterns within their psilocybin-producing gene clusters.

Jack M Craig, Dr. Blair Hedges, and Dr. Sudhir Kumar, all at Temple University, have built an evolutionary tree that encompasses 455 primates, every species for which genetic data are available.

A gene known as HbS was the center of a medical and evolutionary detective story that began in the middle 1940s in Africa. Doctors noticed that patients who had sickle cell anemia, a serious ...
