(Phys.org) —A study on human mitochondrial DNA has led to a new estimate of the time at which humans first began to migrate out of Africa, which was much later than previously thought.
A study led by Lluis Ribas de Pouplana, researcher at the Institute for Research in Biomedicine, gives an explanation for the divergent evolution of the genomes of different groups of species. The connection between the function ...

(PhysOrg.com) -- Gene duplications are arguably the driving force of organismal evolution and if they survive, such duplicate genes will diverge in both regulatory and coding genomic regions. Coding divergences, in ...
The ancestor of all hammerhead sharks probably appeared abruptly in Earth's oceans about 20 million years ago and was as big as some contemporary hammerheads, according to a new study led by the University of Colorado at ...
