Marriage to Kathy Schick

In the summer of 1976, Toth met Kathy Schick while the two were working together on an archaeological dig in Ohio. With similar interests and both attending graduate school in Anthropology, they soon began collaborating on their research. Toth and Schick went on to attend graduate school at the University of California, Berkeley and were married during that time. Their marriage was followed by extended periods of fieldwork at

where they conducted research for the next four years under the direction of Berkeley professor Glynn Isaac and
Richard Leakey of the
National Museum of Kenya.
This period was the beginning of a long-term research collaboration between Toth and Schick which has continued for decades.

. From 1982 to 1986 he was a post-doctoral research scientist at the
Institute of Human Origins in Berkeley, Ca., directed by paleoanthropologist
Donald Johanson. From 1986 to the present he has been a faculty member in the College of Arts and Sciences at Indiana University, Bloomington, in the Anthropology Department and the Cognitive Science Program, and has served as an adjunct professor in the Biology Department and the Department of Earth and Atmospheric Science.
In 1986 he co-founded, with Kathy Schick, the Center for Research into the Anthropological Foundations of Technology (CRAFT) at Indiana University, and together they continue as co-directors of CRAFT. In 2003, the couple founded the Stone Age Institute, a non-profit education and research facility located in Indiana and dedicated to research into human origins. Toth and Schick continue as co-directors and executive board members of the Stone Age Institute.
Over the course of his career Toth has participated in public education programs which help provide children and adults access to educational materials and related media on subjects such as human evolution, archaeology, anthropology, and big history. One such program is a big history project with Kathy Schick titled
Origins: From the Big Bang to the World Wide Web which began in 2010 with a multi-year museum installation at the
Mathers Museum of World Cultures as well as the permanent, multifaceted educational website which has been running since 201
Another example of Toth's public education projects are the video courses he created for the
Big History Project, which is a public education program created by
Bill Gates and
David Christian. Toth's courses for the project include one title
''Introduction to'' ''Archaeology''and another titled

During investigations at Gona, Ethiopia in 1999, Toth discovered the fossil cranium of a Homo erectus individual which dates to about 1.2 million years ago.
In his decades of experimental research into the manufacture and use of early stone tools, Toth has replicated thousands of Oldowan and Acheulean artifacts, many of which he has used in controlled experiments involving such things as cutting through thick hides and the butchering of large animals (all animals used in these studies had died of natural causes, no animals were killed for the purposes of this research). This research revealed that the most important tools to the early stone tool makers may have been the sharp-edged flakes that were removed from the choppers and pebble tools, rather than the
choppers and pebble tools themselves, as had been previously supposed. Flake assemblages had been a largely ignored part of archaeological collections from sites of this time period because they were thought to have been a by-product of the manufacture of the more formal choppers and other pebble tools. Toth’s research supported the idea that these flakes were the simple, highly effective base of early stone tool technology.
Research with Kanzi
In 1990, Toth began a long-term collaborative research project, along with Kathy Schick and psychologist
Sue Savage-Rumbaugh, to observe the bonobo Kanzi as he learned to make and use stone tools. Over the course of this research, Toth and Schick worked together to teach Kanzi, by example, to flake stone and use the sharp flakes produced to cut a length of rope that would allow access to a desired food reward. The goal of this research was to compare the products of human tool makers to those of our prehistoric counterparts (which we can see archaeologically through the tools they produced), as well as to those of non-human primates who have not evolved to make stone tools. This research would allow the scientists to investigate what, if any, cognitive and biomechanical adaptations required for stone tool technology may be present in modern day primates.
Given a supply of
chert for flaking and stone to use as a hammerstone, Kanzi was able to learn to flake stone, yielding sharp flakes that he was able to use to cut through rope and obtain his edible reward. The flakes and
cores produced by Kanzi’s efforts were less sophisticated than the earliest stone tools recognized by archaeologists, suggesting that there is probably an earlier stone tool technology that is not recognized archaeologically.
Olduvai Gorge Coring Project
In 2014, Toth, along with three other principal investigators including Kathy Schick, Jackson Njau, and Ian Stanistreet, began the Olduvai Gorge Coring Project to extract geological cores around the gorge in order to increase our knowledge of the geological history of the Olduvai Gorge area. This coring project is the first of its kind to take place at Olduvai and the project has resulted in the extraction of more than 600 meters of geological cores from 3 different locations around the gorge, with the deepest core resulting in 236 meters of recovered core material. This project more than doubles the known stratigraphic sequence at Olduvai, adding 400,000 years of deposits dating as far back as 2.4 million years ago. The coring project is ongoing, with further coring planned and a variety of researchers analyzing the extracted core material.
