• It is impossible to know when hominids began to use fire, since fires often occur naturally, and early hominids probably made use of this. However, we know that Homo erectus was a fire-user.
• In the Zhoukoudian caves in China, burned bones and stones, thick ash beds, and charcoal have been found, showing that fire was being used 500,000 years ago.
• In the cooler climate of Eurasia, fire would have provided much-needed warmth. It could also be used for cooking.
• Charles Darwin was a British naturalist who in 1859 wrote a very important book called the Origin of Species.
• Darwin had realized that animals and plants change over long periods of time because they compete for food and mates.
• Only the “best” or “fittest” creatures survive, and those alive today are the result of millions of years of evolution. This is called natural selection.
• Darwin caused a furor in 19th-century England by applying his theories to humans; the discovery of Neanderthal fossils proved that humans are also the product of evolution.
