7. Natural Selection and Evolution Test

What are the 2 types of evolution?

• Microevolution (Evolution can occur on a small scale affecting a single population)

• Macroevolution (Evolution can occur on a small scale affecting a single population)

• Microevolution (Evolution on a large scale affecting changes in species across populations)

• Macroevolution (Evolution on a large scale affecting changes in species across populations)
