In this module, you are going to learn that a very powerful mechanism, natural selection, leads to evolutionary change. We are going to have a detailed look at what is required for this natural selection. And, knowing these conditions, we can judge whether traits in humans are evolving at the moment. This is a surprisingly simple module. I am looking forward to discuss human evolution with you at the end!

This is a real puzzle-module. We are going to decipher the language of DNA, and see that mutations in this DNA lead to new variation. As we saw, variation is the raw material for natural selection. Thus, take your pen and pencil and unravel with me the code of your own DNA!

In the first two modules, we have asked ourselves whether we experience evolutionary change, and if so, how this change comes about. In this module, we will explore who this "we" is anyway: is it us, the individual? Is it our species? Our genes? Who is in charge here?

In this module, we will take a look at the limitations to evolution. Despite the strength of the process of natural selection, some things simply are not possible. Evolution has to play by the rules, and this module will explore what those rules are.

In this module, we will have a look at the future. How will humans evolve, and, as our impact on the world increases, how will we affect the evolution of other organisms?
