Mammals were evolving alongside the dinosaurs, and share a common ancestor with dinosaurs. When the dinosaurs became extinct, they left behind habitats and resources, so the mammals evolved explosively to adapt and exploit the opportunities.
The first primates appeared around 60 million years ago (mya).
Great apes (the group of primates that includes us) appeared between 18 and 12 mya. The Human lineage diverged from the Chimpanzee lineage about 6 mya. Anatomically modern humans arose about 200,000 years ago. Behaviourally modern humans arose at least 50,000 years ago.
