So, what have we learned in this course. Well, a lot of things, right? But we've learned that the evidence for evolution is overwhelming. It occurred, just like the earth has changed over time, continents have moved, organisms have evolved, organisms have changed through time Now we have a lot to learn yet about the mechanisms of evolution. We have very strong, strong evidence for adaptation in natural selection, there is and we gave you a lot of examples where some of that knowledge is very important for human health and well being. And then finally, we've, we talked a lot about how evolutionary science is important for humans. We need to teach it. We need to teach it well in order to create a more literate society about why it's important to us and why it actually saves lives. We still have a lot to think and learn of course. But one of the things that we should be thinking about in teaching is evolution is not just the theory. It happened. But there are many hypotheses that we can apply to all the evidence of evolution. But there's a wealth of evidence we'll provide, we provide you with a lot, and we want you to teach the scientific controversies. There are a lot of controversies, and one I brought up was how are all these species of humans related to one another? We still don't know a lot about that, and then how do we know what we think we know? That is, what is the nature of science? The nature of science is about proposing a hypothesis to explain things that we see and trying to bring more evidence to bear upon whether these, this hypothesis or that hypothesis is correct. So, thank you very much for attending this course. We hope you learned a lot, and we hope to see you some time in the future in another course.
