(Phys.org)—A team of researchers from the U.S. and Spain has found that domestication of canines appears to have led to an increase in harmful genetic changes in dogs. In their paper published in Proceedings of the National ...
In evolutionary terms, the human population has rocketed in seconds. The news that it has now reached 8 billion seems inexplicable when you think about our history.
