General
This scientific field is defined as the study of non-human primates, including their anatomy, genetics, behavior, and ecology.
What is Primatology?
Discovered in 1974, this famous 3.2-million-year-old partial skeleton of Australopithecus afarensis was named after a popular Beatles song.
What is Lucy?
This form of locomotion involves moving exclusively on two legs, a defining characteristic of the hominin lineage.
What is bipedalism?
Grooming
What is this widespread social behavior that involves animals picking through each other's fur to clean it, which helps reduce tension and reinforce social bonds within a group?
Fossils
What are these preserved remains, impressions, or traces of once-living organisms provide scientists with direct physical evidence or prehistoric life?
This 18th-century Swedish botanist who created the modern system of binomial nomenclature to classify living organism.
Who is Carolus Linnaeus?
This anatomical term describes a condition where the lower face or jaw projects forward, a trait prominent in early hominins but reduced in modern humans.
Ilium
What is the large flaring upper portion of the hip bone that became short and broad over hominin evolution to support upright balance?
This general term refers to how a primate group is organized in terms of the number of adult males and females living together, such as one-male/multi-female or multi-male/multi-female.
What are primate residence patterns?
This remarkable 3.6 MYO volcanic ash trail in Tanzania preserves the earliest direct evidence of hominin bipedalism.
What are the Laetoli footprints?
Paleoanthropology
What is subfield of anthropology focuses on the study of early humans and their ancestor through the recovery and analysis of the fossil record?
This genus of hominins is frequently referred to as the robust australopithecines due to their massive chewing muscles and large grinding teeth.
What is Paranthropus?
Sagittal crest
What is this ridge bone running along the top midline of the skull serves as an attachment site for massive chewing muscles, found on robust hominins like Paranthropus?
Polygynandry
Taphonomy
Jane Goodall, Dian Fossey, and Britue Galdikas were famously given this collective nickname by Louise Leaky for their groundbreaking work with great apes.
What are the Trimates?
This species lived around 4.4 MYA in Ethiopia and possesses a unique grasping big toe alongside bipedal adaptations.
What is Ardipithecus ramidus?
What is foramen magnum?
This specific behavior is often observed in chimpanzees and baboons when a mother refuses to abandon her deceased baby, sometimes holding it for weeks.
Occurring roughly 66 MYA, this massive global event wiped out the non-avian dinosaurs and marked the transition into the Cenozoic era.
What is the K-T extinction?
Discovered in 1912 and exposed as an elaborate hoax in 1953, this fraudulent skull set back the study of human evolution by tricking scientists into believing early humans had massive brains but ape-like jaws.
What is the Piltdown Man?
This 6-to-7-MYO fossil from Chad is widely considered one of the earliest known hominin species, boasting a remarkably flat face for its geological age.
What is Sahelanthropus tchadensis?
This large socket in the pelvic bone receives the head of the femur to form the hip joint, transferrring weight efficiently during bipedal walking.
Solitary
Paleoanthropologists rely on this specific field of science to reconstruct past environments, weather patterns, and ecosystems using data from ice cores and fossilized pollen.
What is paleoclimatology?
