James F. O'Connell is Distinguished Professor Emeritus of Anthropology at the University of Utah. He is a member of the National Academy of Sciences of the United States of America and is on the editorial board of the Proceedings of the National Academy of Sciences. [1] [2]
The University of Utah is a public research university in Salt Lake City, Utah, United States. As the state's flagship university, it offers more than 100 undergraduate majors and more than 92 graduate degree programs. The university is classified among "Doctoral Universities – Very High Research Activity" with "selective, higher transfer-in" admissions. Graduate studies include the S.J. Quinney College of Law and the School of Medicine, Utah's first medical school. As of Fall 2018, there are 24,735 undergraduate students and 8,251 graduate students, for an enrollment total of 32,994.
O'Connell was born in San Francisco, California. He became interested in natural history as a child, facilitated by the California Academy of Sciences in Golden Gate Park, which was near his family home. After graduating from St. Ignatius College Preparatory, he undertook coursework at University of San Francisco for two years before he moved across the bay to attend the University of California at Berkeley.
San Francisco, officially City and County of San Francisco and colloquially known as SF, San Fran, or "The City", is the cultural, commercial, and financial center of Northern California. San Francisco is the 13th most populous city in the United States, and the fourth most populous in California, with 883,305 residents as of 2018. It covers an area of about 46.89 square miles (121.4 km2), mostly at the north end of the San Francisco Peninsula in the San Francisco Bay Area, making it the second most densely populated large U.S. city, and the fifth most densely populated U.S. county, behind only four of the five New York City boroughs. San Francisco is the 12th-largest metropolitan statistical area in the United States, with 4,729,484 people in 2018. With San Jose, it forms the fifth most populous combined statistical area in the United States, the San Jose–San Francisco–Oakland, CA Combined Statistical Area.
The California Academy of Sciences is a research institute and natural history museum in San Francisco, California, that is among the largest museums of natural history in the world, housing over 46 million specimens. The Academy began in 1853 as a learned society and still carries out a large amount of original research. It is California's oldest museum.
Golden Gate Park, located in San Francisco, California, United States, is a large urban park consisting of 1,017 acres (412 ha) of public grounds. It is administered by the San Francisco Recreation & Parks Department, which began in 1871 to oversee the development of Golden Gate Park. Configured as a rectangle, it is similar in shape to but 20 percent larger than Central Park in New York City, to which it is often compared. It is over three miles (4.8 km) long east to west, and about half a mile (0.8 km) north to south. With 24 million visitors annually, Golden Gate is the third most-visited city park in the United States after Central Park and the Lincoln Memorial.
O'Connell earned his undergraduate and postgraduate degrees at UC Berkeley. Working with Robert Heizer, his PhD dissertation examined the prehistoric archaeology of Surprise Valley, California. [3] After graduation, he took a post at the University of California at Riverside for three years before accepting a research fellowship at the Australian National University (ANU). There he undertook ethnoarchaeological work with Alyawarra and Anmatjere speakers (dialects of Arrernte) near Bendaijerum station in the Northern Territory of Australia. Though originally planned as a study of site structure, O'Connell had been recently influenced by Robert MacArthur's Geographical Ecology, [4] which led him to undertake quantitative observations of subsistence behavior [5] in addition to studies of material remains. [6] After several years at ANU, O'Connell accepted a position at the University of Utah.
Robert Fleming Heizer was an archaeologist who conducted extensive fieldwork and reporting in California, the Southwestern United States, and the Great Basin.
The Australian National University (ANU) is a national research university located in Canberra, the capital of Australia. Its main campus in Acton encompasses seven teaching and research colleges, in addition to several national academies and institutes.
Since arriving at Utah in 1978, O'Connell has continued to undertake ethnoarchaeological and archaeological research in Western North America and Australia. He also started additional projects in Africa, most notably his research with Hadza hunter-gatherers in Tanzania. Collaborating with Kristen Hawkes and Nicholas Blurton Jones, research has sought to explain the evolution of human life histories, [7] Plio/Pleistocene hominid hunting strategies [8] and the emergence of the genus Homo [9] from an evolutionary ecological perspective.
The Hadza, or Hadzabe, are an indigenous ethnic group in north-central Tanzania, living around Lake Eyasi in the central Rift Valley and in the neighboring Serengeti Plateau. There are, as of 2015, between 1,200 and 1,300 Hadza people living in Tanzania, however only around 300 Hadza still survive exclusively based on the traditional means of foraging. Additionally, the increasing impact of tourism and encroaching pastoralists pose serious threats to the continuation of their traditional way of life.
Homo is the genus which emerged in the otherwise extinct genus Australopithecus that encompasses the extant species Homo sapiens, plus several extinct species classified as either ancestral to or closely related to modern humans, most notably Homo erectus and Homo neanderthalensis. The genus is taken to emerge with the appearance of Homo habilis, just over two million years ago. Genus Homo, together with the genus Paranthropus is probably sister to A. africanus in the genus Australopithecus, which itself had previously split from the lineage of Pan, the chimpanzees.
To date, he has published over 150 journal articles and book chapters, including seminal work applying evolutionary ecology to human behavior, [10] novel ethnoarchaeological work linking behavioral ecological explanations of human behavior to its material consequences [11] and applying these insights to prehistory. [12] Applications of the latter include recent work directed toward understanding the Pleistocene colonization of Sahul (Pleistocene Australia/New Guinea). [13] [14]
Evolutionary ecology lies at the intersection of ecology and evolutionary biology. It approaches the study of ecology in a way that explicitly considers the evolutionary histories of species and the interactions between them. Conversely, it can be seen as an approach to the study of evolution that incorporates an understanding of the interactions between the species under consideration. The main subfields of evolutionary ecology are life history evolution, sociobiology, the evolution of inter specific relations and the evolution of biodiversity and of communities.
Ethnoarchaeology is the ethnographic study of peoples for archaeological reasons, usually through the study of the material remains of a society. Ethnoarchaeology aids archaeologists in reconstructing ancient lifeways by studying the material and non-material traditions of modern societies. Ethnoarchaeology also aids in the understanding of the way an object was made and the purpose of what it is being used for. Archaeologists can then infer that ancient societies used the same techniques as their modern counterparts given a similar set of environmental circumstances.
A hunter-gatherer is a human living in a society in which most or all food is obtained by foraging. Hunter-gatherer societies stand in contrast to agricultural societies, which rely mainly on domesticated species.
The Oldowan was a widespread stone tool archaeological industry (style) in prehistory. These early tools were simple, usually made with one or a few flakes chipped off with another stone. Oldowan tools were used during the Lower Paleolithic period, 2.6 million years ago up until 1.7 million years ago, by ancient Hominin across much of Africa, South Asia, the Middle East and Europe. This technological industry was followed by the more sophisticated Acheulean industry.
Evolutionary anthropology is the interdisciplinary study of the evolution of human physiology and human behaviour and the relation between hominids and non-hominid primates. Evolutionary anthropology is based in natural science and social science. Various fields and disciplines of evolutionary anthropology are:
The grandmother hypothesis is a hypothesis to explain the existence of menopause in human life history by identifying the adaptive value of extended kin networking. It builds on the previously postulated "mother hypothesis" which states that as mothers age, the costs of reproducing become greater, and energy devoted to those activities would be better spent helping her offspring in their reproductive efforts. It suggests that by redirecting their energy onto those of their offspring, grandmothers can better ensure the survival of their genes through younger generations. By providing sustenance and support to their kin, grandmothers not only ensure that their genetic interests are met, but they also enhance their social networks which could translate into better immediate resource acquisition. This effect could extend past kin into larger community networks and benefit wider group fitness.
Colin Peter Groves was a British-Australian biologist and anthropologist. Groves was Professor of Biological Anthropology at the Australian National University in Canberra, Australia.
Meave G. Leakey is a British paleoanthropologist. She works at Stony Brook University and is co-ordinator of Plio-Pleistocene research at the Turkana Basin Institute. She studies early hominid evolution and has done extensive field research in the Turkana Basin. She has Doctor of Philosophy and Doctor of Science degrees.
The term Plio-Pleistocene refers to an informally described geological pseudo-period, which begins about 5 million years ago (mya) and, drawing forward, combines the time ranges of the formally defined Pliocene and Pleistocene epochs—marking from about 5 mya to about 12 kya. Nominally, the Holocene epoch—the last 12 thousand years—would be excluded, but most Earth scientists would probably treat the current times as incorporated into the term "Plio-Pleistocene"; see below.
Tim D. White is an American paleoanthropologist and Professor of Integrative Biology at the University of California, Berkeley. He is best known for leading the team which discovered Ardi, the type specimen of Ardipithecus ramidus, a 4.4 million-year-old likely human ancestor. Prior to that discovery, his early career was notable for his work on Lucy as Australopithecus afarensis with discoverer Donald Johanson.
Glynn Llywelyn Isaac was a South African archaeologist who specialised in the very early prehistory of Africa, and was one of twin sons born to botanists William Edwyn Isaac and Frances Margaret Leighton. He has been called the most influential Africanist of the last half century, and his papers on human movement and behavior are still cited in studies a quarter of a century later.
The Middle Stone Age was a period of African prehistory between the Early Stone Age and the Later Stone Age. It is generally considered to have begun around 280,000 years ago and ended around 50–25,000 years ago. The beginnings of particular MSA stone tools have their origins as far back as 550–500,000 years ago and as such some researchers consider this to be the beginnings of the MSA. The MSA is often mistakenly understood to be synonymous with the Middle Paleolithic of Europe, especially due to their roughly contemporaneous time span, however, the Middle Paleolithic of Europe represents an entirely different hominin population, Homo neanderthalensis, than the MSA of Africa, which did not have Neanderthal populations. Additionally, current archaeological research in Africa has yielded much evidence to suggest that modern human behavior and cognition was beginning to develop much earlier in Africa during the MSA than it was in Europe during the Middle Paleolithic. The MSA is associated with both anatomically modern humans as well as archaic Homo sapiens, sometimes referred to as Homo helmei. Early physical evidence comes from the Gademotta Formation in Ethiopia, the Kapthurin Formation in Kenya and Kathu Pan in South Africa.
Jisk'a Iru Muqu is a pre-Columbian archaeological site 54 kilometers (34 mi) south-east of Puno, Peru. The site lies in the mountains at elevation 4,115 meters (13,500 feet), in the Aymara community of Jachacachi, adjacent to the Ilave River drainage, of the Lake Titicaca Basin, Peru. Occupation of Jisk'a Iru Muqu spans from the Late Archaic to the Formative.
Environmental anthropology is a sub-specialty within the field of anthropology that takes an active role in examining the relationships between humans and their environment across space and time.
The sexual division of labour (SDL) is the delegation of different tasks between males and females. Among human foragers, males and females target different types of foods and share them with each other for a mutual or familial benefit. In some species, males and females eat slightly different foods, while in other species, males and females will routinely share food; but only in humans are these two attributes combined. The few remaining hunter-gatherer populations in the world serve as evolutionary models that can help explain the origin of the sexual division of labor. Many studies on the sexual division of labor have been conducted on hunter-gatherer populations, such as the Hadza, a hunter-gatherer population of Tanzania.
Hominid dispersals in Europe refers to the colonisation of the European continent by various species of hominid, including hominins and archaic and modern humans.
Robert Laurens Kelly is an American anthropologist who is a Professor at the University of Wyoming. As a professor, he has taught introductory Archaeology as well as upper-level courses focused in Hunter-Gathers, North American Archaeology, Lithic Analysis, and Human Behavioral Ecology. Kelly’s interest in archaeology began when he was a sophomore in high school in 1973. His first experience in fieldwork was an excavation of Gatecliff Rockshelter, a prehistoric site in central Nevada. Since then, Kelly has been involved with archaeology and has dedicated the majority of his work to the ethnology, ethnography, and archaeology of foraging peoples, which include research on lithic technology, initial colonization of the New World, evolutionary ecology of hunter-gatherers, and archaeological method and theory. He has been involved in research projects throughout the United States and in Chile, where he studied the remains of the Inca as well as coastal shell middens, and Madagascar, where in order to learn about farmer-forager society, Kelly has participated in ethnoarchaeological research. A majority of his work has been carried out in the Great Basin, but after moving to Wyoming in 1997 he has shifted his research to the rockshelters in the southwest Wyoming and the Bighorn Mountains.

Evolutionary psychology has traditionally focused on individual-level behaviors, determined by species-typical psychological adaptations. Considerable work, though, has been done on how these adaptations shape and, ultimately govern, culture. Tooby and Cosmides (1989) argued that the mind consists of many domain-specific psychological adaptations, some of which may constrain what cultural material is learned or taught. As opposed to a domain-general cultural acquisition program, where an individual passively receives culturally-transmitted material from the group, Tooby and Cosmides (1989), among others, argue that: "the psyche evolved to generate adaptive rather than repetitive behavior, and hence critically analyzes the behavior of those surrounding it in highly structured and patterned ways, to be used as a rich source of information out of which to construct a 'private culture' or individually tailored adaptive system; in consequence, this system may or may not mirror the behavior of others in any given respect.".
Evolutionary biologists have developed various theoretical models to explain the evolution of food-sharing behavior—"the unresisted transfer of food from one food-motivated individual to another"—among humans and other animals.
