Early tool-makers/geologists

In the fields of paleoanthropology and archaeology we are not just searching for bones of our early ancestors. Instead we are seeking knowledge of our biological and technological origins and how these characteristics have changed over time. Presently, the earliest fossil bipedal hominins are between 4- 7 million years old (discussed more in the next [...]

Human activity from the Recent Past

In the last 100,000 years, human behavior evolved to a lifestyle with trading, burying their deceased, fishing, more cooked food, and the creation of figurative art and better-made tools. At the end of the last glacial period (~11,700 years ago), humans were adjusting to changing environments from an overall shift in global climate. During this, [...]

Monkey see, monkey do…monkey is hungry!

In the study of archaeology, interpreting the behavior and lives of early humans and their ancestors is based on an examination of material they left behind.  Guiding the TBI students in their learning this module is Dr. Sonia Harmand, an experienced field archaeologist with expertise on early stone tools. But why would anyone study stone [...]

Lothagam – a geologist’s wonderland

Lothagam- basaltic lava flows, lahars, faulting, volcanic ash, erosion, river channel deposits, muddy floodplains and ancient soils, lake deposits, shell beds, oyster reefs, more volcanic ash, more faults, more erosion, more deposition, and so much more! Day 1 Dylan's gazes out of the lowry as we approach Lothagam. Camping spot. [...]

Lakes in the Turkana Basin – past, present, and future

When the Turkana Basin was not dominated by river systems, the rock record indicates several paleo-lakes occupied the region and sometimes reached over 100 kilometers away from the present lake margin. Instead of just recording the depositional environments that have occurred, a field geologist will try to determine the causes of such changes in order [...]

Rivers- past and present

Interpreting and reconstructing depositional environments of the past involves an understanding of modern processes acting on the Earth surface that can form a particular rock and/or sequence of rock layers. In the Turkana Basin, the bulk of the last 4 million years are made up of ancient river deposits. One river in particular, the Omo, [...]

Map it!

The rock record of the Turkana Basin contains a history of tectonic movement, volcanic activity, and climatic alterations that have all affected precipitation patterns, river systems, lake levels, and more. Understanding these morphological changes provides a more complete picture and possible factors that have affected early life in this region. Vital to this research are maps and [...]

Local Turkana students visit researchers at TBI

The Turkana Basin Institute (TBI) is not only a non-profit organization interested in scientific research in the Lake Turkana region, in addition, TBI works closely with local communities on health and education. The vast majority of the people (population near 900,000) that live on this semi-arid, harsh environment are nomadic pastoralists with cares focused on [...]
