I am joined by Uppsala University professor of animal conservation biology, Jacob Höglund. He is literally the perfect person to talk to about today’s Nazi lie: human biodiversity. He has a book from Oxford University Press called Evolutionary Conservation Genetics, which is the thing that Nazis obsess about. The book is great because it doesn’t get lost in the weeds with too much theory, it has tons of examples, and totally unintentionally, it absolutely demolishes the Nazi case for racial segregation and ethnic cleansing. I’m sure this is not at all where you expected to be interviewed for this book. Welcome to the podcast, Dr. Höglund. Jacob Höglund: Thank you very much. I'm glad to be here. Mike: All right. So obviously, you were not intending to write a book to dispel Nazi lies writing a book about the genetics of extinction and conservation. So talk a little about what inspired you to write this book and what you learned along the way. Jacob: Yeah, you're right. It's a completely different context, but the background is basically that the earth is facing a major biodiversity crisis. Biodiversity is defined as three basic levels; ecosystems, species, and genes. And I focus on genetic diversity. I'm concerned about loss of genetic diversity, and that's why I wrote the book. Mike: Alright. By page two, you’re already undermining the core of Nazi racial theory by asserting that diversity, both genetic and demographic, is important for avoiding extinction. Before we get into why that is, talk a little about what diversity means in this context, because the human biodiversity crowd might be like, “Well, I believe we need diversity too.” But what they mean is a humanity segregated by race. So, what do we mean by that diversity here? Jacob: Actually, in biology it means completely opposite. It's a bit complicated, but fragmentation-- So basically biodiversity loss or habitat loss, leads to smaller populations that become separated in a sense. Imagine that you have a large population which is connected, and then human action causes land loss and changing land use and all that sort of stuff. So populations that once were big and connected now become small and fragmented. And these small and fragmented populations tend to lose genetic variation through a process called genetic drift. Genetic drift is basically the random loss of genetic variants. This is what conservation genetics is trying to understand and to counteract. Mike: Okay. You talk a bit about segregation and its evolutionary consequences in your book. Obviously, you don’t mean to refer to race here, but for practical purposes the effect of segregation would be genetically the same for humans. Talk about what happens to species with segregated populations. Jacob: Yeah. We biologists don't talk about segregated populations; we talk about fragmented populations. So it's a small distinction, right? But as I tried to explain before, when you have fragmentation because of this process called genetic drift, you lose genetic diversity. Genetic diversity is sometimes also called heterozygosity when geneticists talk to one another. Mike: What does heterozygosity mean exactly? How is it defined? Jacob: It's again, a bit technical and complicated. But many organisms like plants and animals, the ones we are most familiar with, they are what we call diploid. And what a diploid is, it means that basically, these organisms have one genome from mom and one genome from dad. So it means that on every position in the genome, there would be one variant inherited from mom and one from dad. And when they are different, the two positions are different. That's called an heterozygous site. And when they're the same, so when Mom and Dad had the same variant, that's called a homozygous site. And the more sites that are heterozygous, the more diverse the genome is. Mike: Right. So it's kind of like having enough genes in the gene pool to make sure that– Okay, so now let's talk about why genetic diversity is important. Why do we want heterozygosity? Jacob: We want diversity in the populations because if we have– One way I can explain this is that, you know, in our homes many people keep good-to-have boxes; you save nuts and bolts and nails and whatever-- you put them in this box that you find is good to have in the future. Because if you face a problem in your home and you want to repair something, it's good to have ...
