The excavation and analysis of human remains has long been a staple in archaeology. Archaeologists can learn a lot about a civilization from the remains that they have left and how they take care of their remains. You can tell a lot about the values of a civilization based on their burial rituals and treatment of their own remains.  And through the use of forensic archaeology, human remains can be used to give insight into more recent events. With forensic archaeology, more recent remains can be used as evidence in criminal cases. Although the use of excavated remains is a fundamental part of archaeology, and has provided a great deal of information to archaeologist it does not come without controversy. Many people object to the excavation of remains because it does not show respect to the person who died.

Forensic Archaeology is a subset of archaeology that uses artifacts in order to help solve criminal cases. In forensic archaeology, human remains are very important. Archaeologists utilize human remains to determine information about a deceased person from before the person dies. This information age, sex, time of death, method of death, etc. can be crucial to a criminal case. In many cases criminals would have gotten away without being caught without the use of forensic anthropology. But does the good that comes from the use of human remains outweigh the negatives? Some say no.

Since the first excavations of human remains have been conducted there has been controversy. In many cultures, people are taught to show respect to the dead. It is disrespectful to disturb the remains of an already buried person. This can be trouble for archaeologists who need to use human remains to gather information about things. There have been many instances of clashes between archaeologists and people who believe that the use of human remains is wrong. This has occurred many times pertaining to the excavation of ruins belonging to indigenous peoples. Many descendants of Native American tribes are against the excavation of burial sites. A recent example of archaeologists clashing with people who oppose the use of human remains occurred in Britain. People have called for the reburial of the body of a young girl whose body had been excavated 80 years ago to pay respect to the girl. Archaeologists argue that the body is needed to conduct research.

In the end there are both positives and negatives to excavating human remains. The information obtained from human remains gives us great insight into events in both the past and the present, but it is also very controversial. I believe that if the correct respect is given when excavating the remains, that the use of human remains is fine and is an integral part to archaeological discoveries.

Studying human remains reveals unique information to archaeologists about a civilization’s customs and traditions.  In addition to cause of death, archaeologists can create a complete profile of the body’s lifestyle based on physiological features combined with intense critical thinking. Similarly, the remains of animals in the area can also provide great insight into a society’s culture by helping archaeologists gain a better understanding of the type of environment that the people lived in.  What kind of predators threatened their safety?  Did they domesticate animals and train them to perform actions to benefit the entire community?  A group of archaeologists used animal remains to analyze a unique aspect of Mayan culture—the interaction between different social and economic classes based on the distribution of animal resources.

This stone-carved depiction of a social-elite seizing resources from a lower class member of Mayan society serves as one of the few examples of art depicting social-class division.

Very little was known about the political and economic systems of Mayan society, as compared to archaeologists’ extensive knowledge of their advances in art and astronomy.  The way animal resources were distributed offered clues to the ways in which different social classes interacted, and archaeologists learned that their societies were not homogeneous by any means.  Instead, there were complicated systems in place to regulate trade relations, food distribution, and accessibility to species.  Because animals were used so widely for hides, tools, jewelry, and musical instruments, studying the geographic distribution of these resources revealed that there were elite classes that controlled a majority of the valuable resources.  But surprisingly, the middle classes used the widest variety of animals, as the wealthiest people only used exotic animals, such as jaguars and crocodiles, and the poorest could only afford to use inexpensive animals, such as a variety of fish and shellfish.

These animal bones, teeth and a cut jaw bone from a tapir, are an example of the ways Mayans used animal bones to create tools and instruments for daily use in society.

The study of animal bones has provided insight into the way Mayan cities interacted with surrounding villages through trade and commerce and has provided such extensive information because Mayan culture relies so heavily upon animal resources accomplish.  I am amazed by the amount of information that the archaeologists were able to infer about human cultures and tendencies from the examination of seemingly-unrelated artifacts.  Similar observations and critical thinking are applied when analyzing human remains as when uncovering truths about a society and their culture.  In the case of the Mayan civilization, the discovery of specific animal remains led archaeologists to believe that there were stricter class boundaries than previously thought.  The emergence of social hierarchy is an aspect of the “big picture” of Mayan civilization and social structure.  Without the creative approach to this investigative archaeology, they would be missing evidence of a significant aspect of Mayan culture which serves as further evidence of the often-overlooked sophistication of the ancient American civilizations.

Forensic archeology, to my surprise, is not what we often see on television. Although it involves people who have already passed away, often times we only have remnants of them left – maybe only a bone or two or small pieces of different bones. However, this branch of archeology is much more important than we give it credit for. It serves as a means of bringing about closure to the immediate families of the deceased, whether it is through a proper burial or information regarding their passing. As such, this branch of archeology is much more humanitarian in nature and can be thought of as a way of giving back to society. As we have learned, respect for the dead (often times in terms of a proper burial) is something that we hold to be very important and this dates back to circa 60,000 years ago, so this need for closure is not something new and we finally have a way of obtaining it in cases such as the one written here.

In this article from 2010, we see that forensic archeology was used to find a member of the Disappeared, people who were killed and had their bodies hidden during The Troubles, a period of thirty years marked by violence in Ireland. Unlike in television, this is not an easy process. It involves working with many parties, such as ICLVR and the family of the deceased, using tools like LIDAR, and a painstaking amount of time (months to years) on the field and mapping possible locations of the bodies. However, this work does pay off. The primary archeologist in the article said the following about his experience finding the body of one of the Disappeared, Charlie Armstrong:

“I’ve got to know Charlie’s widow, Kathleen, and their children very well over the years and know how much it means to them to bring Charlie home and give him a proper burial in consecrated ground. I feel proud that the team has helped them bring their many years of waiting to an end.”

While television often spreads misinformation on forensic archeology, it brings the field into the eyes of the public, much like The Big Bang Theory does. Personally, I would not be interested in physics if it weren’t for the introduction to The Big Bang Theory and Michio Kaku (a physicist and public advocate of science). And in both fields, we see an increase in enrollment of students.

Understanding the environment is an essential aspect of an archaeologist’s job to understand the context in which societies formed and lived and artifacts are found.  More specifically, trees can serve as valuable records that describe the climate of an area over the period of hundreds or thousands of years.  Researchers in Southern Africa are using the analysis of radiocarbon dating and tree rings in Baobab trees to interpret how the climate has changed in Southern Africa over the past thousand years, and to use these interpretations to try to form ideas about the societies that developed in these areas.

Since tree growth is dependant upon the environment, it can be a good indicator of the climate at a specific time.  Tree growth is a complex process, but temperature and soil moisture temperature can be the leading factors contributing to tree growth, thus tree growth can tell us a lot about the temperature and soil moisture of an area at a specific time period, among other things.  

Radiocarbon dating is a common process of evaluating the age of a tree, and radiocarbon samples can also be taken from a tree and can be used to determine such things as the moisture and temperature of tree cellulose at a given time period.  Radiocarbon dating works by measuring the amount of carbon-14 in an object relative to other carbon isotopes in the object and measuring the amount it has decayed over time.  

Tree rings can also usually be used to determine the age of tree, and act as a record of the quality of the tree’s health throughout its lifespan.  Tree ring growth varies with the climate, and thus it can be strong in the spring or weak in the winter and used to determine differences in tree health and of the wider climate’s condition at specific time spans.

Researchers analysed the Baobab trees from Northeastern South Africa for the amount of waterfall in the region and included the timeframe of the Kingdom of Mapungubwe in the period of time they studied.  The group of researchers from Britain, Romania, and South Africa determined that, “The wettest period was AD1075 or [1075CE] in the Medieval Warm Period, and the driest periods were AD1635, AD1695 and AD1805 during the Little Ice Age.”1

The data collected can also be used to try to better understand the region at the time the first Bantu-speaking farmers settled the land.  Better understanding the environment in which these farmers developed their land can be valuable knowledge in determining the political and economic systems of the area, of which were based upon the success of agriculture to allow for specialization at the time.2

Recognizing the importance of evaluating the environment in interpreting the context in which people lived and artifacts are found can help better fathom our perceptions of an area at a specific time.  The analysis of radiocarbon dating and the use of tree rings are important tools that researchers can use in their experiments, and this reality is manifested in the importance researchers placed on their analysis of Baobab trees to understand how the climate changed – and how people might have adapted to its change – in the South Africa.

The environment can reveal a lot about a culture. If the environment is favorable for agriculture, people take up a sedentary lifestyle. If it is the opposite, or people have access to additional resources, agriculture is less likely to be a focus. Yet this general rule is challenged by the Inca Empire, and their persistence to pursue agriculture in a region unfavorable to crops.

The basic process of creating terraces.

Mountain climates do not inherently support agriculture. Little precipitation falls in the Andes. Steep slopes also prevent growth of plants as what little precipitation that does fall erodes soil and thus washes plants away. Mountain temperatures fluctuate, often becoming much colder at night and shortening the growing season.
However, the Incas found a way around these problems, with terrace agriculture. By cutting flat planes into the mountain, the Incas were able to create areas of suitable farmland. Bounded by stone walls, these areas are able to withstand the problems associated with Mountain climates. Along with domesticated species of plants suited to harsh conditions, the Incas were able to farm.
Yet why would the Incas put in the tremendous amount of work to make an area unsuitable for sedentary life, suitable? The answer lies within the environment. Cultures that struggle with agriculture often have earlier examples of rock art (signs of praying to the Gods). As religion is spurred by a harsh environment, it becomes even more central to the culture.
In the case of the Incas, religion played a huge role in their culture, likely due to the environment. As to why they would have stayed, or even continued higher; (major areas like Machu Picchu and Cuzco are over 7,000 ft. above sea level) this is likely due to being closer to heaven (the Inca highly revered their sun God, Inti). As religion led to the Incas moving up in altitude, the environment only became tougher for a sedentary lifestyle. Yet the practice of terrace farming shows the Incas dedication to their lifestyle, and persistence as a people.

Though harsh in terms of climate, the Andes region is bountiful concerning precious medals. The existence of the precious metals gold and silver would have confirmed that they were in a holy area of the world, and that their connection to their Gods would only be improved as they increased in altitude. The use of these metals in Inca throne rooms and temples shows the influence the environment had upon their lives.
Through just the knowledge of the environment, a lot can be seen about a culture. What environmental challenges are presented determine what kind of lifestyle inhabitants will lead. In the case of the Incas, their harsh conditions resulted in creativity and adaptation against the natural environment, so as to pursue their religious lifestyle. Understanding how environmental conditions pressure and shape a human life is imperative to understanding a culture.
