    Study Notes

    • Approximately seven million years ago, the human lineage split from that of chimpanzees, marking the beginning of humanity's evolution.
    • Over 20 early human species or hominins emerged, with some becoming extinct and others potentially being ancestors to modern humans.
    • These hominins displayed varying degrees of human-like physical and behavioral traits, such as large brains, small teeth, bipedality, and tool use.
    • Early humans are divided into three major groups: early hominins, australopithecines, and the homo genus.
    • Early hominins, who lived between seven and 4.4 million years ago in Africa, retained many ape-like traits but showed early human-like characteristics like small canines.
    • Australopithecines, living between 4.4 and 1.4 million years ago, showed a significant shift towards human-like traits, particularly consistent bipedal locomotion.
    • Homo species, dating back over two million years ago, became increasingly human-like with larger cranial capacity, sophisticated stone tool technology, and control of fire.
    • Homo species were the first to migrate out of Africa and explore the rest of the world.
    • Only one hominin species remains today: Homo sapiens, shaped by millions of years of evolution and embarked on a journey of exploration and industry.
