The Human Evolution Timeline
Primates includes all lemurs, monkeys, and apes, along with their extinct relatives. Traits: forward-facing eyes, large brains relative to body size, and opposable thumbs.
800,000 Generations Ago The last common ancestor with humans and gibbons lived around 20 mya. Great Apes LCA candidate: Proconsul, an inhabitant of the Miocene forests in East Africa, stands as a landmark in the evolutionary journey toward self-awareness. This early ape lacked a tail and exhibited a mixture of arboreal and terrestrial traits, providing […]

Not us: Other hominin species lived in niche spaces along side our ancestors. Species like Paranthropus aethiopicus, Paranthropus boisei, and Paranthropus robustus, dating from about 2.7 to 1.2 million years ago. These species are characterized by robust craniodental features, likely related to their diet. A contemporary genus to early Homo.

116,000 Generations Ago This genus is more directly ancestral to humans and includes several species, such as Australopithecus afarensis (famously represented by “Lucy”), Australopithecus africanus, and others. Australopithecines show a greater commitment to bipedalism and have features more closely resembling modern humans, although they still retained some adaptations for climbing. This genus is known for

320,000 Generations Ago Last Gorilla-Chimp-Human ancestor: The last common ancestor of gorillas, chimpanzees, and humans likely lived about 8 to 10 million years ago. Both the Nakalipithecus and Chororapithecus genuses are candidates. Genus Nakalipithecus: This “might” be the leading plausible candidate. From Kenya, they are dated to about 10 million years ago. Location: Emerged in Western

As various great ape species fill niche areas around the globe, branches emerge. The last common ancestor of all known great apes, including humans, lived about 16.5 mya. That branch leads to modern orangatans, which split off again about 12.5 mya. The last known split of the modern orangatan was about 400,000 years ago. Orangutan

After the split of great apes and humans about 16 mya, and the split of the chimpanzee branch from humans about 7 mya, the two modern pan species split: chimpanzees and bonobos. Around 1.5 to 2 million years ago, the evolutionary branches of ancient primates led to the distinct emergence of what we now recognize

2,600 Generations Ago (from 2020 CE) Long before the sails of European explorers dotted the horizon, the Australian continent witnessed the arrival of its first human inhabitants. Archaeological evidence, such as ancient tools and cave art, suggests that people arrived in Australia at least 65,000 years ago, marking one of the earliest known human migrations

76,000 Generations Ago Homo erectus is a direct ancestor of modern humans and represents a key point in human evolution where evidence of a truly omnivorous diet becomes clear, including the use of tools for hunting and processing both plant and animal foods. This species shows significant brain enlargement and other adaptations indicative of complex

12,000 Generations Ago Neanderthals and denisovans in the genus Homo had a common ancestor about 370,000 BCE (current estimates range from 250,000 to 500,000 BCE). Though neanderthals, denisovans, and sapiens share a common ancestor, they didn’t evolve directly from each other. That common ancestor from which all three evolved from was likely a later Homo

Denisovan: This bracelet dates from 70,000 to 40,000 BCE. It was discovered inside the Denisova Cave beside ancient human remains. The Denisova Cave is a cave located in Siberia, Russia. Other cave finds include woolly mammoth and woolly rhino bones. Scientists say there is evidence that the bracelet’s maker used a drill. This is the

7,000 Generations Ago All humans today share a single grandma, circa 175,000 BCE. We know this because all humans alive today share our ancestor’s haplogroup L genes — from our X chromosome. She was one of many thousands of women living in eastern Africa. Many maternal lines survived for many generations but ultimately over time
11,000 Generations Ago All humans today share a single grandpa, circa 275,000 BCE. We know this because all humans alive today share our ancestor’s haplogroup A genes — from our Y chromosome. He was one of many thousands of men living in eastern Africa. Many paternal lines survived for many generations but ultimately over time

The “out of Africa” migration took place in many waves of which two are widely recognized: 130,000 to 100,000 BCE, and the Southern Dispersal around 70,000 to 50,000 BCE. Through genetic DNA testing we know that none of the genetic differences prior to circa 70,000 BCE exist in today’s humans.

14,000 Generations Ago Homo heidelbergensis: Long spears made hunting large animals more safe. The oldest wooden spears found so far were found in Germany and dates to circa 400,000 BCE. In fact, they are currently the oldest known wooden artifacts. The find included 3 wooden spears, stone tools, and the butchered remains of more than

60,800 Generations Ago Species: Likely Homo erectus, our direct ancestor. The footprints found in Ileret, Kenya represent the oldest undisputed evidence of hominins walking upright in an efficient manner characteristic of modern humans. Our style of upright walking, which Homo erectus appears to have shared, is energy-efficient and adapted for long distances. It involves a

260,000 Generations Ago CHLCA candidate: Often considered one of the earliest potential hominins, Sahelanthropus tchadensis, best known from the “Toumai” skull found in Chad, exhibits features that suggest bipedalism but remains debated due to limited fossil evidence. With two human anatomical traits, small canine teeth, and a spinal cord hole in the cranium further forward

Genus Homo: Rapid brain growth in our human ancestors started about 800,000 BCE. Now, by rapid brain growth we mean about 600,000 years! Larger complex brains helped early humans to survive. They interacted with each other and their surroundings in new and different ways.

The earliest known stone tools date back to at least 3.3 million years ago. They are identified by their purposeful flaking patterns, sharp edges, and location with other more identifiable artifacts or fossils. They are then verified with microscopic analysis confirming repetitive use.
1,200 Generations Ago Humans used bone and ivory needles like these about 28,000 BCE to sew warm, closely fitted garments. These bone needles are from Xiaogushan, Liaoning Province, China, and are dated to about 28,000 to 21,000 BCE.

31,600 Generations Ago Burned flint tools dated to circa 790,000 BCE were discovered at Gesher Benot Ya’aquov, Israel. Control of fire is one of the key traits of the genus Homo.
