    Study Notes

    Oldowan Tool Kit

    • Simple stone tools, typically one or a few flakes chipped off a core stone.
    • Used during the Lower Paleolithic period (2.9 - 1.7 million years ago).
    • Found across much of Africa, providing early hominins with evolutionary advantages in food access and raw material processing.
    • Named after Olduvai Gorge in Tanzania, a significant site for paleoanthropological discoveries.
    • 2023 discovery in Kenya suggests tools may be up to 3 million years old, potentially the oldest known.
    • Tools found alongside Paranthropus fossils challenge the assumption that only Homo species used stone tools.
    • Tools were made using least-effort flaking strategies, utilizing fissile rocks like volcanic stones and quartzites.

    Paranthropus robustus

    • Robust australopithecine species from the Early and Middle Pleistocene of South Africa (2.27 - 0.87 million years ago).
    • Characterized by heavily built skulls, high bite forces, and inflated cheek teeth.
    • First remains (partial skull and jawbone) discovered in 1938 at Kromdraai cave, South Africa.
    • 2021 discovery of the DNH 155 cranium in Drimolen Cave, South Africa, dated to 2 million years old – the oldest, best-preserved specimen.
    • Extinct 1 to 1.4 million years ago.
    • Considered a cousin of Homo sapiens, not a direct ancestor.
    • Co-existed with Homo erectus around 2 million years ago, representing divergent evolutionary paths.
    • DNH 155 cranium provides evidence of microevolutionary change in Paranthropus robustus over a short time and limited geographic area, potentially due to climate change.

    Oldowan Tool Kit

    • Oldowan tools (Mode I), simple stone tools made with flakes chipped off a core, were used in the Lower Paleolithic (2.9-1.7 million years ago) across Africa.
    • These tools, though crude, offered significant evolutionary advantages, providing access to new food sources and allowing processing of other materials.
    • The Oldowan industry's name comes from Olduvai Gorge in Tanzania, where many artifacts and fossils were discovered by the Leakeys.
    • A 2023 discovery in Kenya revealed Oldowan tools potentially dating back 3 million years, the oldest yet found.
    • These tools were found alongside Paranthropus fossils, suggesting tool use wasn't exclusive to Homo ancestors.
    • Oldowan toolmaking involved hitting a fissile core (e.g., volcanic stone, quartzite) with a hammerstone to create sharp flakes.

    Paranthropus robustus

    • Paranthropus robustus, a robust australopithecine, lived in South Africa's Cradle of Humankind from 2.27 to 0.87 million years ago.
    • Robust australopithecines are characterized by heavily built skulls, strong bite forces, and large cheek teeth.
    • The first P. robustus remains (TM 1517) were discovered in 1938 at Kromdraai cave.
    • In 2021, the DNH 155 cranium, a 2-million-year-old, well-preserved P. robustus skull, was found in Drimolen Cave, South Africa.
    • P. robustus went extinct 1-1.4 million years ago; it's considered a cousin of Homo sapiens, not a direct ancestor.
    • P. robustus coexisted with Homo erectus around 2 million years ago, representing divergent evolutionary paths.
    • The DNH 155 cranium provides evidence of microevolutionary changes in P. robustus over a short timescale and limited geographic area, potentially due to climate change.

    • Makers utilized least-effort flaking strategies with fissile rocks (cores) like volcanic stones and quartzites, struck with hammerstones to create sharp flakes.

    Paranthropus robustus

    • Species of robust australopithecine from South Africa (Cradle of Humankind).
    • Existed between 2.27 and 0.87 million years ago.
    • Characterized by heavily built skulls, strong bite forces, and large cheek teeth.
    • First remains (partial skull) discovered in 1938 at Kromdraai cave by Gert Terblanche.
    • DNH 155 cranium, a 2-million-year-old specimen, is the oldest and best-preserved P. robustus fossil.
    • Went extinct approximately 1-1.4 million years ago.
    • Considered a cousin of Homo sapiens, not a direct ancestor.
    • Coexisted with Homo erectus around 2 million years ago, showcasing divergent evolutionary paths.
    • DNH 155 cranium provides evidence of microevolutionary change within the species over a short timescale, potentially due to climate change.
