Step by Step
1
Who Neanderthals were and where they lived
Neanderthals lived in Europe and western Asia from roughly 400,000 to 40,000 years ago — overlapping in time and geography with early modern humans.
2
Physical adaptations
A stocky build suited to conserving heat in cold climates, large nasal passages (likely for warming and humidifying cold air before it reached the lungs), and a pronounced supraorbital torus (a bony ridge above the eyes).
3
Brain size and tools
Neanderthal brains were equal to or even larger than modern human brains on average (~1,500cc). They made Mousterian stone tools, a more refined tradition than earlier tool types.
4
Evidence of Neanderthal culture
Use of ochre pigment, feather ornaments, and — notably — burial of the dead, as seen at the Shanidar cave site. These findings pushed back against the old stereotype of Neanderthals as unsophisticated "cavemen."
5
The genetic revolution: Svante Pääbo
Svante Pääbo led the effort to sequence ancient DNA, successfully sequencing the Neanderthal genome in 2010 — work that earned him the Nobel Prize in 2022. This confirmed that non-African modern humans carry roughly 1–4% Neanderthal DNA, direct evidence of historical interbreeding between the two groups.
Applied Walkthrough
1
Picture a Neanderthal burial site like Shanidar: a body deliberately placed in the ground, with evidence suggesting flowers or ochre pigment may have accompanied it — behavior once assumed to be uniquely "modern human." Now picture a lab decades later, where Svante Pääbo's team extracts and sequences DNA from ancient Neanderthal bone fragments.
2
The result: if you have non-African ancestry, somewhere between 1% and 4% of your own genome likely traces back to Neanderthals — meaning some of your ancestors and some Neanderthals, at some point, had children together.
Exam Application
Exams test whether you can state where and when Neanderthals lived, name the scientist behind the Neanderthal genome sequencing and what prize he won, and what percentage of Neanderthal DNA modern non-African humans carry.
⚠ Common Trap
Don't say Neanderthal DNA appears equally in all modern human populations. The 1–4% figure specifically applies to non-African populations, reflecting interbreeding that occurred after early modern humans left Africa and encountered Neanderthals in Eurasia.
