Ch16 Evolution Of Populations
A population is a group of people living together in a given geographical area. By studying the evolution of a population we get to see some answers on the changes that humans go through and the cells within the body. The quiz below is set to test your understanding of the chapter 10 on the evolution of population. Give it a try and see how much you remember. All the best!
