What is punctuated equilibrium?
400
Large scale evolutionary change
What is macroevolution?
400
The concept of humans selecting desired traits in species
What is artificial selection?
400
This process occurs when individuals move between populations, introducing new genetic material
Gene flow

Why did the population of pepper moths change?
industrial revolution, smoke, trees turning black, the mutated black moths were able to survive and reproduce better and their population grew.
