The field of archaeology is undergoing a series of reformations at present, and one of those changes includes a push for archaeology and archaeologists to be more mindful in assisting local communities.  This is where Larry Zimmerman and Jessica Welch come in as they are pioneering and leading the way forward with the archaeology of homelessness.  Their archaeological work is providing new and greater insights into homeless communities, and it is their hope that this research can and will be used to better assist local homeless populations and resident communities.  This blog post will discuss their research and what specifically the archaeology of homelessness is.

The archaeology of homelessness is an area of inquiry involving the use of archaeological methods to identify and interpret the material culture evidence of homeless populations.  This is a field of study that Zimmerman happened upon by accident when he was working on a historic period site in St. Paul, Minnesota.  The site had been taken over by homeless groups for many years, and through systematic and required excavations to get to the historic site Zimmerman discovered years of evidence of the homeless occupation of the area.  Rather than discard the material as trash he noticed specific trends in the homeless populations' artifacts that very closely resembled other sites he had previously excavated. This piqued his interests into the possible research avenues of such an inquiry.

When Zimmerman moved onto a job in Indianapolis, Indiana, he began a more substantive research project into the archaeology of homelessness.  He included Jessica Welch in the project partially because she had been homeless for a period of time and her knowledge and experience could be useful in the project.  She later became a permanent member of the team, providing greater understanding to the creation the project and interpretation of its results. 

Zimmerman and Welch’s partnership resulted in the creation of a typology/classification system of various homeless sites throughout Indianapolis.  These sites are classified by use and chronology, demonstrating either temporary or permanent use as well as individual or larger group utilization.  Zimmerman and Welch also observed the material culture evidence left behind at these sites and made some startling realizations that shatter many stereotypical views about homeless individuals.  First, there was an abundance of a variety of food and alcoholic containers but very little evidence of drug use.  The food containers present at the site are most often fast food containers, which demonstrates that these are easy to obtain resources and also illustrates the ease of access homeless individuals have to these resources compared to food available in grocery stores.  When canned goods were present they were often unopened or crudely opened.  The reason was not due to a lack of interest or desire to consume them but the practicality of not being able to.  Many homeless people do not have a can opener or other means of opening the cans of food provided to them.  Zimmerman and Welch have advocated for the distribution of can openers if groups feel compelled to distribute canned goods, although they also point out the issues related to cooking such foods in certain places based on their site analyses. 

Another interesting discovery is the number of travel sized personal hygiene products found at the sites.  This demonstrates a desire among homeless individuals to maintain personal hygiene, but the majority of these items were unopened.  Again, the reason for this was a lack of resources to use them.  Without regularly available running water (let along clean running water) these items are appreciated but not able to be used by the homeless.  This demonstrates another need among the homeless and a better means of assisting them with cleanliness.

Zimmerman and Welch also identified a series of cached items, which are items stored while individuals make short term trips away from their base camps.  This is a system regularly utilized by foraging groups, of which homeless populations most resemble culturally.  These caches contain items of personal value to the homeless, such as photos and private possessions, as well as utilitarian items, such as personal medications and extra clothing.  These caches most often resemble piles of trash and are often collected and discarded by well meaning citizens or government agents meant to clean up public spaces.  Zimmerman and Welch oppose such disposal practices as they often cause further harm to the person and dignity of homeless individuals who lose their access to necessary medications or links to their pasts and present identities.

Ultimately, the information gained through Zimmerman and Welch’s work is opening up new information about homeless populations and more effective means of assisting them, which can be used by a variety of organizations and individuals that assist homeless individuals.  Zimmerman and Welch advocate for further research in urban and rural areas frequented by homeless populations as a means of better assisting those populations, particularly as these populations are diverse and there is no universal solution to aiding all of them.

Extending the Family Tree: Recent Discoveries on the Denisovans Expand Our Knowledge of Human Evolution


On May 1, 2019 a startling new discovery was announced.  This announcement had been over 30 years in the making, and the wait was well worth it because this new information expands our current knowledge of hominids and human evolution.  Today’s blog post will discuss the implications of the discovery of a mandible fragment found in the Himalayan Mountains.

In 1980 a Tibetan monk discovered the fragment of a mandible (lower jaw bone) in the Baishiya Karst Cave in Xiahe, China.  This piece was eventually donated to the Lanzhou University, where it came into the possession of scholars Fahu Chen and Dongju Zhang.  They began studying the piece, and eventually they teamed up with researchers Svante Pääbo and Jean-Jacques Hublin of the Max Planck Institute.  Together and with respective teams of colleagues in China and Germany this group launched a study on the mandibular fragment. 

When initial DNA analyses failed (due to a lack of usable DNA in the specimen) they turned to protein analysis to determine the species to which this piece belonged.  They were successful with this analysis, isolating several proteins that they used to determine the origin species.  This led to the discovery that this mandible belonged to a member of the Denisovan species, which had only been previously identified through DNA of a lone finger bone.  They also were able to determine, through dental aging methods, that this individual was most likely an adolescent at their time of death.

These pieces of information are remarkable in and of themselves, but there was even more gleaned from this information.  The initial place of discovery, the Baishiya Karst Cave high in the Himalayan Mountains, meant that Denisovans were well adapted to high altitude living, which had until recently been associated solely with archaic Homo sapiens.  The presence of the Denisovan fossil at this location, as well as the discovery of a specific gene that allows for such adaptations (the EPAS1 allele) in Denisovan fossils, means that our hominid ancestors were far more advanced that previously thought.

This was not the only surprising discovery, however.  Previous work had demonstrated that modern Tibetans and various other human groups carry with them DNA from Neanderthal, Denisovan, and four yet to be identified hominid species.  This means that our hominid ancestors were not isolated species, as previously thought, but instead were different breeds of the same species or closely related species that were not only able to but were regularly interbreeding.  This process led to the passing on of many beneficial genes that continue to exist among modern humans today. 

Together, all of this information is creating quite the stir in the paleoanthropological and human evolution communities.  Once previously believed ideas and paradigms are shifting or being abandoned in the face of new evidence, and this additional knowledge is demonstrating how complex evolutionary relationships are.  It also demonstrates how advanced our hominid ancestors were, making way for new ideas and realizations about what it means to be human.

Endangered Language Profile: Basque


Biotzetik Basque Choir



Language and culture are closely tied together, and when one disappears the other is sure to follow (if it continues to exist at all).  There is a great deal of importance in preserving languages and cultures, as a result, and today’s blog post highlights one such language that is considered endangered: the Basque language.  This blog post will discuss what the Basque language is and the means of preserving and revitalizing its use among not only those who identify as Basque but also by enthusiasts.

The Basque language, also commonly referred to as Euskara, is a language spoken by the Basque people, who hail originally from northern Spain and southern France but large populations of Basque are scattered throughout the Western United States (specifically Nevada and Idaho).  The Basque language is unique as it is considered a language isolate, meaning it is not similar to any modern-day European languages.  Instead, Basque is considered to have been influenced by various languages spoken in Europe throughout history, including languages now long extinct (e.g. Celtic, Latin, and Gascon).  

The Basque language is identified as an agglutinative language, which is defined by the use of multiple prefixes or suffixes on a root word to change the meaning of the phrase or sentence.  This language type is common throughout the world.  The Basque language, however, does have some unique aspects to it, specifically in that the language has no Æ’ consonant and no simple r sound.  Additionally, there is no consonant after the initial s and no consonant clusters within the language. These are features, however, found within Castilian Spanish, a dialect of Spanish spoken throughout northern Spain.  It is believed that Castilian Spanish and Basque borrowed lexicons and grammar from each other.

While the Basque people have undergone a series of grave events throughout their history (e.g. extermination under Franco’s dictatorship in Spain and modern-day governmental interventions throughout Spain and France) the Basque are determined to keep their language alive.  Special language courses in Basque are provided throughout Europe and the US to native Basque and those interested in learning the language.  These programs have been very successful in revitalizing the Basque language.  As one Basque individual living in the US noted this success may be credited to the special status given to Basque language speakers, who are considered more prestigious than people who are simply Basque.
