MC1R--gene associated (indicate) Neandertals had red hairs, fair skin, and
freckles
FOXP2 -- gene Neandertals had-- used for speech
Neandertal Tool Technology
Mousterian tool tradition is named after the site of Le Moustier,
France --stone tools
○
Flakes were removed from a prepared core using the Levallois
method --compared to acheulean --pitch (sap and resin to glue
spear point to their spears)
○
More complex and sophisticated
○
-
Neandertal subsistence -Neandertal hunting and the role of meat in the
diet
La Cotte de St. Brelade
Jersey Islands, in the England channel--stampeding
§
○
Vindija Cave Site, Croatia
The bones had a high amount of nitrogen 15 in their collagen
§
Depicted that they relied on meat
§
○
El Salt, Spain
Looked at coprolites (feces)--50,000 year old poop--identify
fats ( found fats associated with meats)
§
Two compounds associated with plants--berry diet
§
Found parasites (different kind of "worms")

We will watch part of a video called "Decoding Neanderthals."
The video presents an interesting discussion of recent developments in the
reconstruction and analysis of the Neandertal genome. It highlights the work of
a team of scientists led by geneticist Svante Pääbo and examines the
relationship between Neandertals and modern humans.
Scientists have discovered evidence of interbreeding between Neandertals and
humans. About 1-3% of the human genome of non-African populations is
Neandertal.
Evidence of interbreeding
○
The Denisovans
Discovered at Denisova Cave, southern Russia
○
DNA from a finger bone was analysed and identified as belonging to
an archaic human
group separate from Neandertals and modern humans.
○
Geneticists have discovered Denisovan DNA in the modern human
genome. Represents
about 5% of some populations in East Asia especially Melanesia and
Aboriginal Australian people.
