The mammal ancestor had 19 autosomal chromosomes and 2 sex chromosomes. University of California, Davis scientists help reveal the genome of the common ancestor of…
The findings suggest that V-set domains evolved farther back in the evolutionary tree than previously believed. The tiny marine invertebrate’s genes shed new light on…

The study reveals that chromosome-level engineering can be achieved in mammals. Researchers engineer the first sustainable chromosomal alterations in mice. In nature, evolutionary chromosomal changes may…
Early tetrapod. The skulls of tetrapods had fewer bones than extinct and living fish, limiting their evolution for millions of years, according to the latest…
Representation of the modes of locomotion practiced by Sahelanthropus. Bipedalism was common among the earliest known representatives of humankind, probably on the ground but also…
Artistic reconstruction of the reptile adaptive radiation in a terrestrial ecosystem during the warmest period in Earth’s history. The image depicts a massive, big-headed, carnivorous…
Evolution has long been thought to be random, however, a recent study suggests differently. Evolution might be less random than we thought. Evolution has long…
Analysis of the genome and proteome shows that eukaryotic evolution gave rise to the regulatory function of chromatin. Two meters of DNADNA, or deoxyribonucleic acid,…
Scientists Discover a 4-Billion-Year-Old Ancient Piece of Earth’s Crust Underneath Western Australia
The earth is composed of three main layers: the crust, the mantle, and the core. Lasers pave the path for finding ancient crust. Curtin University…

Recent research analyzes mathematical models created to deduce conclusions about how evolution works at the level of populations of organisms. A study examines the benefits and…
Researchers have uncovered a source of oxygen that may have influenced the evolution of life before the advent of photosynthesis. Scientists at Newcastle University have…
