Pre-hominid human evolution all the way back to LUCA.
The last common ancestor with humans and orangatans lived around 16 mya. Great Apes LCA candidate: Kenyapithecus is an extinct genus of great ape that lived in Kenya from around 16 to 14 million years ago. It is considered a potential candidate for the last common ancestor of all great apes, including humans, chimpanzees, gorillas, […]

660,000 Generations Ago The Last Common Ancestor (LCA) of the Great Apes, a.k.a. the Hominidae family, marks a pivotal point in our evolutionary history, encompassing the origins of orangutans, gorillas, chimpanzees, and humans. This ancestor species, likely existing between 15 to 19 million years ago, represents the shared lineage from which all modern great apes

CHLCA candidate: This genus includes Ardipithecus ramidus (like “Ardi”) and possibly earlier species like Ardipithecus kadabba. Ardipithecus shows a mix of bipedal traits and adaptations for climbing, reflecting a transitional form in human evolution.

CHLCA candidate: Known from Kenya, Orrorin tugenensis is another early form, with femoral evidence suggesting bipedality, indicating it was likely an early walker.
Discovered in 2016 in the Panama Canal area, Panamacebus transitus has been identified as the earliest known monkey to have reached the Americas, dating back approximately 21 million years. This find significantly alters our understanding of primate migration and geographical distribution during the Miocene epoch. This arrival in the Americas is a remarkable testament to

48,000 Generations Ago NSLCA Candidate: This ancient human species challenges traditional views by suggesting that some of our human ancestors bore a closer resemblance to modern humans than previously believed. Homo antecessor, which existed long before Homo sapiens and Homo heidelbergensis, displayed distinctly modern human-like features, including a flatter face and a more refined nose,

In the verdant landscapes of Laetoli, Tanzania, beneath a layer of volcanic ash from a nearby eruption, a remarkable story is preserved. Dating back 3.66 million years, a series of footprints capture a fleeting moment in time when early hominins walked across the wet ash. These footprints, attributed to Australopithecus afarensis, represent one of the

Speculative branch of humans. Maybe a long lost hybrid: In the evolving tapestry of human history, the emergence of Homo naledi represents a captivating mystery that challenges traditional narratives of linear progression. Positioned within the intricate web of human evolution, Homo naledi could exemplify a complex branch woven from ancient threads. Imagine a scenario where

Homo heidelbergensis lived in Africa, Europe and Asia from 700,000 to 200,000 years ago. They coexisted with humans in Africa, Europe, and Asia from our emergence around 315,000 years ago until their extinction about 200,000 years ago. Imagined Image: A Homo heidelbergensis campsite a few thousand years before they went extinct, set in a lush European

Discovered in 2013 and first dated in 2017, Homo naledi and humans coexisted in South and East Africa from our emergence around 315,000 years ago until their extinction about 236,000 years ago. It is possible that we share a common ancestor with them, but research is pending. Homo naledi lived in South Africa from 335,000 to

Discovered in 2019, Homo luzonensis inhabited the Luzon area north of Manila in the Philippines from at least about 67,000 to about 50,000 years ago. While current evidence suggests that Homo luzonensis may have become extinct before the documented arrival of Homo sapiens around 35,000 to 40,000 years ago, the exact timing of their extinction

Discovered in 2003, Homo floresiensis (also known as the “Hobbit”) inhabited the island of Flores in Indonesia from 190 to 50 thousand years ago. Humans arrived about 50,000 years ago and may be the reason for their extinction. Lineage: Most likely not a Homo heidelbergensis, but a descendant species from an earlier ancient human. Perhaps

Denisovans and humans coexisted in Siberia from about 194,000 to around 40,000 years ago. While their exact cause of extinction remains debated, competition with modern humans and climate change are thought to be contributing factors.

Just as human looks vary widely, Neanderthals did too. This

When Homo sapiens first emerged, their population in Africa was likely just a few hundred thousand, while the total hominin population, including other species like Neanderthals and Homo heidelbergensis, may have ranged from 1.1 to 2.1 million. During this period, Homo sapiens were primarily found in Africa, while other hominins occupied broader ranges across Eurasia,

Cognitive Revolution By 70,000 BCE. Population range: 500,000 to 2.5 million. Given the uncertainties and lack of direct data, the following are speculative estimates. Africa-Middle East: 50-60% or 600,000 to 1 million people Africa, being the origin of modern humans, likely had the highest population density at this time, particularly in Sub-Saharan regions which were

Earliest known agrarian society in the Americas zone: In Oaxaca, Mexico, the site of Guilá Naquitz provides evidence of early plant domestication, particularly of squash, around 8000 BCE, with subsequent developments including maize and beans.

Deep orange or reddish-brown atmosphere: The second atmosphere’s formation was crucial and occurred just before or alongside the formation of Earth’s oceans, which directly supported the evolution of organic molecules and prebiotic microenvironments. The second atmosphere began to develop around 4.5 to 4 billion years ago, as volcanic outgassing released gases trapped in the Earth’s
