LONDON Kevin Byard Youth Jersey , Dec.23 (Xinhua) -- Mammals evolved a greater variety of forms in the first few million years after the dinosaurs went extinct than in the previous 160 million years of mammal evolution, according to a study published Wednesday by the University College London (UCL).
