After the dinosaurs became extinct around 66 million years ago, mammals had the opportunity to become abundant and diversify. With the ecological niches left vacant, mammals evolved into various forms, eventually leading to the rise of larger mammals and the eventual dominance of species like primates and, ultimately, humans. This period marked the beginning of the Cenozoic Era, often referred to as the "Age of Mammals."
