How often do you check your cell phone or email each day? Use Twitter or Facebook? Can you stand not to “stay in touch” for even one day? We’re used to being able to hear from people anywhere in the world at any time, with just a few taps on a keyboard or telephone pad. Through most of human history people could only communicate when they were within shouting distance. When alphabets came along, our ancestors could create messages on stone or wood and later on parchment (made from animal skin), or paper, made from wood pulp. Then, of course, the message had to get from one person to another by way of a messenger. When public mail came along, it made that process much easier and more reliable. That’s where things stood for a long time. Imagine being a soldier in 1804 joining explorers Meriwether Lewis and William Clark on their epic trek across the west to the Pacific Coast. This was territory almost totally unknown at the time to European Americans. You’ve left behind your family and all your friends. Now you have no way of finding out what happened to those dear to you. Did your father or mother die? Did a sister get married? How many babies were born? Your loved ones get to be a bit luckier, since in the spring of 1805, the keel boat that carried the expedition to Indian villages for the winter is sent back down the Missouri River with a small crew, and you get a chance to write notes to your loved ones, reassuring them that you are okay. A lot can happen during a 2½ year span like the one endured by members of the expedition! Finally, in September of 1806, you and your colleagues return to the St. Louis area and find out that most people assumed you were all dead. Now you must figure out as quickly as possible how to reconnect with family and friends. It won’t be easy, since they don’t know you are alive, and you don’t know where they are after so long. How can you even locate everyone you care about? Think about it: If you didn’t have email or a phone of any kind, whose messages would you miss the most? And who would you most wish you could tell about these events in your life?  The Lewis and Clark Expedition followed the Missouri River through miles and miles of vast prairie like this one, full of amazing wild animals like these bison.  This postage stamp honors the 200th anniversary of the Lewis and Clark expedition. And, no, they could not have used a stamp on a letter to send news home. The first US postage stamps weren't issued until 1847.  Dorothy has written about how the horse changed the lives of the Plains Indians and everything that followed.

Have you ever wondered what it would be like to be a wolf? You’re born in a cozy, dark den under the ground, probably along with at least one brother or sister. Your eyes are closed shut, but you can smell and feel your way over to your mother to drink sweet, warm milk from her teats. Your father and older brothers and sisters bring food from their hunts to feed your mother. Your eyes open in about two weeks, but you can’t see much in the darkness of the den. You nap a lot, snuggled up to your siblings and your mom. Then, about a week later, your mother leads you all out of the den into the sunshine. How different it is up here! Now you explore the wild world, wandering among the trees, lapping water from a creek, wrestling and tumbling with your brothers and sisters. After you get bigger and stronger, you and your family leave the den and move to a safe outdoor area. It’s scary at first, being in a strange new place with no dark den for comfort. An older brother or sister watches over you and the other pups while the rest of the family, or pack, goes hunting. When the hunters return you rush up and lick their faces and they share the meat they got on the hunt. All the older wolves in the pack let you climb all over them and nip their ears and tails while they take care of you, protecting you from danger. All that good meat helps you grow into a big, strong wolf, with thick, shiny fur. In the fall, you go along on the hunt and learn how to find game and how best to catch it. Hunting is exciting but dangerous. You or other family members might get kicked by a deer or stomped on by a moose. But if you get injured, the other wolves take care of you until you recover. You are family, and family is what matters.  Grey wolf. © Dorothy Hinshaw Patent, 2014

If I asked you what grain is the most harvested in the world, you’d probably answer either wheat or rice. But the answer is actually corn, more accurately called ‘maize.’ This nutritious crop that originated in Mexico feeds not only people but also animals around the world. We’re used to the wonderfully tender sweet corn harvested in late summer and early autumn, but most maize is actually field corn, more starchy than sweet and used as animal feed or to make cornmeal and flour. For a long time, biologists puzzled about the origins of this important crop. There is no wild plant that looks anything like modern corn, which is actually a giant grass. The closest relative is a scrawny branching plant with hard dark seeds called teosinte. It seems a huge jump from teosinte to corn, yet geneticist George Beadle found in the 1930s that corn and teosinte have the same number of chromosomes and could be crossbred to produce hybrids. With the limited tools available at that time, Beadle deduced that only about five genes were involved in creating the differences between teosinte and corn. Fast forward to modern times, when scientists can look directly at DNA and analyze every detail of its structure. We now know that Beadle came very close to the truth—about five regions in the DNA seem to control the major differences between teosinte and corn. For example, these two plants look so very different, yet just one single gene turns a branched plant into a single stalk, like a stalk of corn. Another single gene controls one of the most dramatic and certainly most important traits for farmers—the nature of the seeds and their stalk. In teosinte, each seed has a hard covering. Just one gene eliminates the hard covering and produces a stalk bearing exposed seeds, like an ear of corn. Scientists now use maize as a perfect example of two major ways evolution happens. One way is through major sudden jumps, like the change from a branching plant to a single stalk. The other is the more gradual kind of change that has led to the thousands of different kinds of maize grown by farmers today. There are probably hundreds of varieties of sweet corn and thousands of varieties of field corn. Think about that the next time you bite into a nice crunchy taco made from a corn tortilla.
 Here you can see the major differences between a teosinte plant and a corn plant.
