Did Humans Evolve from Chimpanzees? The Common Ancestor Explanation
False. Humans and chimpanzees share a common ancestor that lived roughly 6–7 million years ago, but humans did not evolve from chimpanzees. The two lineages diverged from the same ancestor — we are evolutionary cousins, not descendants of modern chimps.
"Humans evolved from chimpanzees." is a myth. The scientific consensus is clear, the primary sources are documented above, and the claim does not survive scrutiny. Read on for the full evidence.
"Humans evolved from chimpanzees."
Humans and chimpanzees share a common ancestor. Both lineages diverged from that ancestor roughly 6–7 million years ago and have been evolving independently since. Neither descended from the other.
This is the most common misrepresentation of evolutionary theory, and it is one that evolutionary biologists spend significant effort correcting. The confusion arises from the true fact that humans and chimpanzees are more closely related to each other than to any other living primate — sharing roughly 98.7% of DNA. But genetic closeness is not the same as descent. Understanding why requires understanding what evolution actually claims.
What Evolution Actually Says
Evolutionary theory does not claim that any living species descended from another living species. It claims that all living species descended from earlier, now-extinct ancestors, and that related species share common ancestors at various points in the past. The distinction is critical. Saying "humans evolved from chimpanzees" would mean that at some point in history, a chimpanzee gave birth to a human — which is not what happened and not what the science claims. What did happen is that roughly 6–7 million years ago, there was a population of ape-like primates in Africa from which two separate lineages diverged. One lineage eventually led to modern chimpanzees and bonobos. The other led through a series of now-extinct intermediate species — including Australopithecus and Homo heidelbergensis — to modern humans. Modern chimpanzees were not our ancestors; they are our relatives, descended from the same long-extinct ancestor.
The Common Ancestor
The last common ancestor (LCA) of humans and chimpanzees has not been definitively identified in the fossil record, though several candidates have been proposed. This ancestor was almost certainly an African ape, but it was not identical to modern chimpanzees. Both lineages have been evolving since the divergence — meaning modern chimpanzees are just as "evolved" as modern humans, merely in different directions shaped by different environmental pressures. Genetic analysis has confirmed the divergence date of approximately 6–7 million years ago, with some studies suggesting it may have been more recent (5–6 million years) or involved interbreeding between proto-human and proto-chimpanzee populations for a period after the initial split. Fossil species such as Sahelanthropus tchadensis (~7 million years) and Ardipithecus (~4.4 million years) represent early stages of the human lineage after the split.
Why the Confusion Persists
The misstatement often appears in oversimplified science communication, where "we share 98.7% DNA with chimps" is reported alongside "we evolved from apes" in a way that conflates the two points. It is also fuelled by creationist strawmanning — it is much easier to ridicule "we came from chimps" than to engage with the actual claim about shared common ancestry. A useful analogy: your cousin is not your parent. You and your cousin share grandparents (a common ancestor). Neither of you descended from the other. Chimpanzees are to humans what cousins are to you — related through a shared ancestor, but not the ancestor itself.
The Verdict
Humans did not evolve from chimpanzees. Humans and chimpanzees share a common ancestor that lived 6–7 million years ago, and both have been evolving along separate paths since then. This is not a minor semantic point — it reflects a fundamental aspect of how evolutionary biology works.

Frequently Asked Questions
Did humans evolve from chimpanzees?
No. Humans and chimpanzees share a common ancestor that lived roughly 6–7 million years ago, but humans did not descend from chimpanzees. Both lineages diverged from the same extinct ancestor and have been evolving independently since.
How closely related are humans and chimpanzees?
Humans and chimpanzees share approximately 98.7% of their DNA sequence, making them more closely related to each other than either is to gorillas. They are our closest living relatives. Bonobos (Pan paniscus) are equally close, essentially co-equal relatives alongside common chimpanzees.
Who was the common ancestor of humans and chimps?
The last common ancestor (LCA) has not been definitively identified. It was almost certainly an African ape living 6–7 million years ago, but not identical to modern chimpanzees. Fossil candidates near this branch point include Sahelanthropus tchadensis (~7 million years old) and Orrorin tugenensis (~6 million years old).
Are chimpanzees more evolved than their ancestors?
Yes — just as humans are. Evolution does not stop at any species. Modern chimpanzees have been evolving for the same 6–7 million years that humans have, in response to their own environmental pressures. Neither humans nor chimpanzees represent the "primitive" ancestral form; both are equally evolved, in different directions.
What is the correct way to state the human-chimp relationship?
Humans and chimpanzees share a common ancestor. Alternatively: humans and chimpanzees are more closely related to each other than to any other living primate. Not: humans evolved from chimps, or chimps are our ancestors, or humans are descended from apes (in the sense of any living ape species).
How We Verified This Claim
SmartAss Facts evaluates every popular belief against a three-tier source hierarchy: primary sources (peer-reviewed research, government datasets, and institutional reports), secondary sources (reputable journalism citing the primary), and tertiary sources (general reference). Only primary sources are cited.
For this myth — Humans evolved from chimpanzees. — we reviewed the cited primary sources above, cross-referenced against independent scientific literature, and confirmed the verdict with the consensus position of relevant scientific bodies. Last reviewed: 2026-05-25.
