Paris (France): During a new study scientists have shown that while haemoglobin appeared independently in several species, it actually descends from a single gene transmitted to all by their last common ancestor.
The research which was conducted by scientists from CNRS, Universite de Paris and Sorbonne Universite, in association with others at the University of Saint Petersburg and the University of Rio de Janeiro, have shown that while haemoglobin appeared independently in several species, it actually descends from a single gene transmitted to all by their last common ancestor. These findings were published in BMC Evolutionary Biology.
