Mary W. Marzke was an American anthropologist. Her research focuses on the evolution of the hominin hand. [1]
Mary Marzke was born Mary Walpole in Oakland, California. While in middle school and high school, ski trips with her family friends the McCowns sparked an interest in anthropology as both Professor and Mrs. McCown were physical anthropologists. Professor McCown later went on to serve as one of her Ph.D. supervisors. In 1959, she graduated from the University of California, Berkeley with an A.B. in Anthropology. [2] Following this, she attained her M.A. in anthropology from Columbia University in New York in 1961. [2] Marzke returned to the University of California, Berkeley to earn her Ph.D. in anthropology, completing it in 1964. [2] Her Ph.D. supervisors at the University of California, Berkeley were Professors Theodore McCown and Sherwood Washburn. Marzke died on September 3, 2020, surrounded by family.
Markze began her teaching career by lecturing, then instructing at Hunter Brown College (now Lehman college) in 1963. She then lectured at the University of North Carolina (Chapel Hill) from 1967 to 1969. The following decade, she worked as an acting assistant professor at the University of California from 1976-1977. In 1978, she began working at the Arizona State University as an adjunct visiting professor. Markze has worked at ASU since then, with a 9 year break from 1986 to 1995 when she worked as an anatomist at the Primate Foundation of Arizona. [2] Markze has been a professor at ASU since 2004, most recently teaching courses on primate anatomy and fossil hominins.
Apart from teaching, Markze has done an extensive amount of research throughout her career, with a “special focus on the evolution of the hominin hand and bipedality.” Markze’s research involves “extensive dissections, electromyography, kinematic analysis of joint angle displacement and tendon excursion, and stereophotogrammetry and laser digitizing for 3-D analysis of joint surface areas, angles and curvatures.
Markze has made a number of discoveries including her work that has demonstrated the links between precision gripping, tool behaviors, and hand morphology. Markze used experimental manufacturing of prehistoric hominin tools, behavior studies of chimpanzees, and morphological analysis, to help discern which pre-modern human species were capable of tool-making. [3]
In 2000, Markze conducted a morphological and biomechanical analysis of the early hominin hand found at Olduvai Gorge. Markze's research also addressed “the potential of fossil hominid hands for one-handed firm precision grips and fine precision manoeuvering movements, both of which are essential for habitual and effective tool making and tool use.” [4] In 2008, Markze’s research concluded that "further derived changes to the hands of other hominins such as modern humans and Neandertals did not evolve until after 2.5 Ma and possibly even later than 1.5 Ma." [5] Markze also pioneered the use of 3DGM methods to investigate the evolutionary history of the carpal bones of the hand.
She has appeared on the PBS show Scientific American Frontiers in 2000 in the episode "Life's Really Big Questions". [6]
Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family, which includes all the great apes. This process involved the gradual development of traits such as human bipedalism, dexterity and complex language, as well as interbreeding with other hominins, indicating that human evolution was not linear but weblike. The study of human evolution involves several scientific disciplines, including physical and evolutionary anthropology, paleontology, and genetics.
Homo habilis is an extinct species of archaic human from the Early Pleistocene of East and South Africa about 2.31 million years ago to 1.65 million years ago (mya). Upon species description in 1964, H. habilis was highly contested, with many researchers recommending it be synonymised with Australopithecus africanus, the only other early hominin known at the time, but H. habilis received more recognition as time went on and more relevant discoveries were made. By the 1980s, H. habilis was proposed to have been a human ancestor, directly evolving into Homo erectus which directly led to modern humans. This viewpoint is now debated. Several specimens with insecure species identification were assigned to H. habilis, leading to arguments for splitting, namely into "H. rudolfensis" and "H. gautengensis" of which only the former has received wide support.
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, 2.9 million years ago up until at least 1.7 million years ago (Ma), by ancient Hominins across much of Africa. This technological industry was followed by the more sophisticated Acheulean industry.
Homo rhodesiensis is the species name proposed by Arthur Smith Woodward (1921) to classify Kabwe 1, a Middle Stone Age fossil recovered from Broken Hill mine in Kabwe, Northern Rhodesia. In 2020, the skull was dated to 324,000 to 274,000 years ago. Other similar older specimens also exist.
The Hominini form a taxonomic tribe of the subfamily Homininae ("hominines"). Hominini includes the extant genera Homo (humans) and Pan and in standard usage excludes the genus Gorilla (gorillas).
The flexor pollicis longus is a muscle in the forearm and hand that flexes the thumb. It lies in the same plane as the flexor digitorum profundus. This muscle is unique to humans, being either rudimentary or absent in other primates. A meta-analysis indicated accessory flexor pollicis longus is present in around 48% of the population.
In human anatomy, the abductor pollicis longus (APL) is one of the extrinsic muscles of the hand. Its major function is to abduct the thumb at the wrist. Its tendon forms the anterior border of the anatomical snuffbox.
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.
Anthropology of art is a sub-field in social anthropology dedicated to the study of art in different cultural contexts. The anthropology of art focuses on historical, economic and aesthetic dimensions in non-Western art forms, including what is known as 'tribal art'.
Jane Ellen Buikstra is an American anthropologist and bioarchaeologist. Her 1977 article on the biological dimensions of archaeology coined and defined the field of bioarchaeology in the US as the application of biological anthropological methods to the study of archaeological problems. Throughout her career, she has authored over 20 books and 150 articles. Buikstra's current research focuses on an analysis of the Phaleron cemetery near Athens, Greece.
AL 288-1, commonly known as Lucy or Dinkinesh, is a collection of several hundred pieces of fossilized bone representing 40 percent of a female of the hominin species Australopithecus afarensis. It was discovered in 1974 in Ethiopia, at Hadar, a site in the Awash Valley of the Afar Triangle, by paleoanthropologist Donald Johanson of the Cleveland Museum of Natural History.
Post-canine megadontia is a relative enlargement of the molars and premolars compared to the size of the incisors and canines. This phenomenon is seen in some early hominid ancestors such as Paranthropus aethiopicus.
A hand is a prehensile, multi-fingered appendage located at the end of the forearm or forelimb of primates such as humans, chimpanzees, monkeys, and lemurs. A few other vertebrates such as the koala are often described as having "hands" instead of paws on their front limbs. The raccoon is usually described as having "hands" though opposable thumbs are lacking.
