After returning to TBI from an exciting camping trip, we spent the afternoon relaxing and knapping! We used the raw material we had collected in the field: though everyone put their initials on the material collected, some students decided to share what they had collected (our students were so thoughtful, but whatever happened to survival [...]
We left TBI Turkwel Monday morning for our camping trip, from which we would be returning on Wednesday afternoon. We would be camping for two nights near the village of Nariokotome; the famous hominin site of Nariokotome boy, KNM-WT 15000, is only a few minutes away! On our drive to Nariokotome, we would be making [...]
On Friday, we traveled to the Holocene site of Napaget, a massive and artefact-rich sand dune that overlooks the beautiful Lake Turkana. The site is about an hour away (as the lorry drives), and on the way we passed some truly impressive termite mounds, almost big enough for a person to live in (I wonder [...]
The next morning in class, we were introduced to archaeological vocabulary, necessary to accurately understand and describe stone artefacts. We learned how to describe the physical characteristics, such as: ventral (internal) and dorsal (external) sides of a flake; cortex, or the external skin of the original rock; and negatives (signs of a flake removal) and positives [...]
Because of the successful end of our last excursion in the field, we returned to the same site to try to find other remnants of this ancient primate. When we got back, we did a hill crawl to cover the area below the find, with the thought that over time the fossil skeleton may have [...]
In Human Evolution this week, we discussed how animals with different diets will have coinciding differences in their teeth morphology as well as in other cranial areas, such as the zygomatic and mandible. Similar dietary morphology patterns are observed in hominins as well, which can tell us a lot about both the environment they were living in [...]
Following our first two days of class in the lab, we spent the day in the field Wednesday visiting the site of an important hominin discovery. In an attempt to beat the heat, we boarded the lorry at 7 a.m. to get an early start, arriving in Area 10 by 7:45. Sale and Apolo lead [...]
The second week of Paleontology was primarily spent in the field: for four of the six class days this week, we spent the entire day in the field, using what we learned in the previous week to find and identify fossils. Though a majority of the time was spent prospecting, we also learned the methods [...]
We started the Paleontology module from a broad perspective, making sure to cover a brief history of life on earth as well as the history of evolutionary theory, including the work of such academic greats as Mayr, Simpson, and Dobzhansky. With such a solid base under our belts, we can now start learning mammalian anatomy! To [...]
Map of the Koobi Fora Region As an educational and celebratory culmination to the geology module, we went on a geology-based camping trip to the Koobi Fora region, particularly close to where Richard Leakey established the Koobi Fora Base Camp in 1968. In the early 1970s Richard and Meave Leakey led a crew [...]
Throughout the history of the Turkana Basin, the dominant hydrographic systems that have fluctuated throughout the basin have been fluvial and lacustrine systems. While this fluctuating environment has been a main theme throughout most of the Geology module, students are now turning to studying current day environments to better understand sediment accumulation in past environments. While [...]
For this module, titled Sedimentary Geology and Geochronology of the Turkana Basin, Professor R. Linda Martin will be leading the students back in time as we reconstruct the past landscapes of the Turkana Basin. Professor Martin is currently the Academic Director for the Origins Field School and has been conducting research in the Turkana Basin since 2011. [...]
One of the final concepts we learned about in ecology was the relationships between organisms. Specifically, the relationship between intimacy (a measurement of the proximity in which these animals interact) and lethality (how harmful the relationship is). For example, a lion and a zebra would have low intimacy and high lethality, because they spend very [...]
On Tuesday, the field school explored near the edge of Sibiloi National Park to learn more about adaptive strategies of vegetation in such an arid environment. In particular, we focused on the desert rose, Adenium obesum, a rather amazing tree. The desert rose is an incredibly slow growing tree, growing an average of 1 millimeter [...]
The field school spent a few days learning about vectors, parasites, and the effect they have on people and the communities in the Turkana Basin. A vector is an animal that actively or passively transmits a pathogen from one organism to another; the most obvious example would be the mosquito, whose diverse family is known [...]
On Monday and Tuesday, we had the opportunity to learn from Mpala researcher Kimani Ndung'u who specializes in vegetation studies and is currently investigating the effects of termite mounds on the locale-specific environment. He is also a part of a project (www.forestgeo.si.edu/site/mpala) run by the Smithsonian Tropical Research Institute where they are collecting data for the only savannah plot in their global network.
