About a million years before steak tartare came into fashion, Europe’s earliest humans were eating raw meat and uncooked plants. But their raw cuisine wasn’t a trendy diet; rather, they had yet to use fire for cooking, a new study finds.
How did humans make fire?
The first stage of human interaction with fire, perhaps as early as 1.5 million years ago in Africa, is likely to have been opportunistic. Fire may have simply been conserved by adding fuel, such as dung that is slow burning. … The next stage was to gain the ability to start a fire.

Chris – But we didn’t know they were cutting hair though – did we? … Margarita – Well we know humans lost their body hair, their fur effectively, about 2.5 to 3 million years ago when they moved from more forest habitat into open savannah and, in order to be able to hunt effectively in the hot climate, they lost fur.
How did cavemen die?
Hypotheses on the fate of the Neanderthals include violence from encroaching anatomically modern humans, parasites and pathogens, competitive replacement, competitive exclusion, extinction by interbreeding with early modern human populations, natural catastrophes, and failure or inability to adapt to climate change.
What killed Neanderthal?
One model postulates that habitat degradation and fragmentation occurred in the Neanderthal territory long before the arrival of modern humans, and that it led to the decimation and eventual disappearance of Neanderthal populations.

Nails start in the nail root, hidden under the cuticle. When cells at the root of the nail grow, the new nail cells push out the old nail cells. These old cells flatten and harden, thanks to keratin, a protein made by these cells. The newly formed nail then slides along the nail bed, the flat surface under your nails.

How did cavemen make fire?
Neanderthals living in France roughly 50,000 years ago regularly started fires by striking flint with hard minerals like pyrite to generate a spark, according to a paper published in the scientific journal Nature.
Why do fingernails smell when you cut them?
When you cut your nails, you’re breaking very strong bonds called “Disulfide bridges” which are sourced from cysteine (one of the amino acids which make up keratin). And keratin has a lot of cysteine (thus a lot of sulfur) which gives it that distinctive smell when it is cut.
