What is macroevolution?
1 Answer
Macroevolution is evolution on a large scale, a scale that encompasses more than just the species level.
Explanation:
When we're referring to how the demise of the dinosaurs left room for mammals to evolve or how chimpanzees and humans last shared a common ancestor 6-7 million years ago, we're talking about macroevolution.
Trends in evolution or other large-scale examples, the evolution of amphibians for example, are parts of macroevolution. This is in contrast to microevolution, or evolution on the smaller scale of populations.
