Mammals were around when the dinosaurs were, we/they wer ebasically rodents until 64 millions years ago when the dinoaurs died out. Anatomically modern humans have been around for 500,000 years. Modern humans probably (mostly brain evolution is my theory) is debatable, but at least 50,000 years.
But basically, we're talking about a very long time period. 64 million years and more.

∙ 12y agoEvolution, the change in allele frequency over time in a population of organisms, is still occurring. We have filamentous prokaryote fossils that are at least 3.5 billion years old, though inheritance was more likely horizontal then. Still, for over 3 billion years organisms evolved and are still evolving.
