With all that has been going on in the world and all the important societal problems, I have been despairing that my desire to push for a natural history museum and more evolution education seemed not as important. But it struck me today that it is perhaps one of the most important things we need to do. There are a lot of misunderstandings about evolution, even among people who accept it, that hinder our ability to get along in the world. Understanding two important truths of evolution will go a long way towards healing our societal divides. What are those truths? 1. We are all the same, and that is a good thing. 2. We are all different, and that is also a good thing. These may seem contradictory, but if you understand how they are meant, they make perfect sense.
- We are all the same, and that is a good thing.
When you start really studying life on this planet, it quickly becomes inescapable that we are all connected. We are all part of the same family. Strip off the skin from humans and we see essentially the same underneath. We all share the same skeletons, our muscles and organs are the same, there are no important differences in our brains. Sure, there are differences, but no matter what way we try to divide humans, especially by skin color or nationality, we find that the differences within the groups are greater than the differences between groups. What this means is that the dividing lines are arbitrary and have no biological basis.
When we go beyond humans and look at all vertebrates, we see the same thing. If we compare skeletons, we see the same bones over and over again. Every animal that has four limbs shares the same bone structure. They may look different, but the bones are all the same. All of our front limbs have a humerus, an ulna, and a radius. We all have the same number of fingers and toes. They may look different, they may lose some as they grow from fetus to adult, but they are all there. As we get farther and farther away from direct ancestry and relationships, the superficial differences start piling up, but the core is always the same.
Going even farther, we all share the same base code. We all use essentially the same DNA and RNA. The sequences may be different, but just as all computer programs are different, they all share the same underlying coding language. We all share metabolic pathways, from bacteria to humans.
Why do we see all these similarities? Because we all share an ancestor. Somewhere down the line, we are all related. We are one family. It may be a very extended family, but we are all together. All life on Earth is connected. Through that life, we are all connected to the very rock upon which we stand. Life has shaped the surface of the Earth. It has shaped the air we breath. We all sprang from the same roots. When you look at someone from a different culture, someone with a different skin color, you are not seeing an other, you are seeing a long separated family member. Embrace that connectedness. Now, I know that no one can get more under your skin and angry than a close family member, but at the end of the day, we don’t generally let that tear us apart. No matter how much we may disagree with our family, we still recognize they are family. Just take that feeling and extend it to recognize that every living thing on Earth is also part of your family.
2. We are all different, and that is a good thing.
So if we are all essentially the same, how can we all be different? No matter how closely we are related to someone, there are always differences. Even identical twins are not completely identical. Our DNA and life experiences mean that each and every one of us is different in some way from everyone else. While we all share the same basic body plan and organization, there are always some differences.
Those differences are important. Ask any agricultural scientist and they will tell you that one of, if not the biggest danger in our food supply is the monoculture crops we grow. When everything is the same, that means they also share all the same limitations and vulnerabilities. Monocultures only work when there is no change. But they do not handle change well. And if there is one thing we know about life, it is that change is inevitable. These days, we are pushing change faster than ever before, so this vulnerability to change is deadly.
Purity is the death of a species. We need diversity to weather changes. As new diseases crop up, as weather becomes more unpredictable and changeable, we will need the diversity to be able to handle whatever is thrown at us. The more diverse the population, the more changes we can tolerate. In a diverse population, there will always be some fraction of the population that is prepared for anything that happens. Those people will make sure that we continue. Moreover, they will help those of us unprepared for the changes make it through. When a new disease appears, those that are naturally immune will be key to developing medicines that will allow the rest of us to survive. Those that can handle climatic changes will be the ones to build the structures and infrastructure that will allow the rest of us to weather the storms. We need diversity. If we try to homogenize our culture and our people, we will die.
We need evolution education and a natural history museum.
So how do we get people to understand this? First of all, on a broad scale, we need to teach people a proper understanding of evolution and evolutionary theory. But we have to do it in a way that exemplifies its importance in our everyday lives. We need to get people to understand why they need to understand it. Evolutionary theory affects us every day. People need to understand how.
We need natural history museums for a multitude of reasons, but two very important ones apply here. First, they will stand as storage houses of information. They are a public recording of the changes that have taken place and are taking place. Secondly, they are a way to teach people who are not in school. Even if they don’t pay that much attention to the details in the museum, they will see a record of the changes. Museums can be designed to showcase the importance of evolution, the advantages of diversity, and the dangers of reducing that diversity. Museums are one of the most trusted sources of information. We need to leverage that to showcase both the interconnectedness of life on Earth and its diversity and why that has allowed its continued existence. It also can showcase what happens when that diversity is not there.
One may argue that history museums would be better at this. The advantage of history museums is that it makes it personal and easy to make it easy for people to relate to it. The disadvantage is that it makes it personal and easy for people to get defensive about it. Natural history museums can teach these lessons on a canvas that people can view and learn from more dispassionately, without it feeling like a personal assault upon their culture that can often happen in history museums.
To be sure, many people will feel that any mention of evolution is an assault upon their worldview, so I am not advocating the idea the natural history museums are inherently better. Instead, I am advocating the view that all types of museums work better when there is a diversity of museums that can tell the stories from different angles. Without a natural history museum, we lack an important viewpoint in the public arena. By building a museum network, we can spread the ideas much more effectively. A natural history museum will not hurt other local museums. It will help all of them. We don’t need just a natural history museum. We need a natural history museum, a local history museum, an international history and cultural museum, an art museum, and other museums. In Arkansas, we have some of the history, art, and culture, but we do not have a natural history museum. As such, we lack that long and broad view that can only come from an understanding of natural history.
