Early life and education

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.

Career

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]

<span class="mw-page-title-main">Human evolution</span> Evolutionary process leading to anatomically modern humans

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.

<i>Homo habilis</i> Archaic human species from 2.1 to 1.5 mya

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.

<span class="mw-page-title-main">Oldowan</span> Archaeological culture

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.

<i>Homo rhodesiensis</i> Species of primate (fossil)

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.

<span class="mw-page-title-main">Hominini</span> Tribe of mammals

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.

<span class="mw-page-title-main">Hand</span> Extremity at the end of an arm or forelimb

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.
