what changes did climatic shift bring about in the ancient man's life
Answers
Answer:Fire has long played a role in myth—from Prometheus in ancient Greece, who stole fire from the heavens and earned the wrath of the gods, to Raven in the Pacific Northwest, whose feathers turned black as he brought fire to the world.
But even though fire has been pivotal in human history, much remains unknown about the steps by which our ancestors learned how to use it. A new study suggests this may have been catalyzed by a prolonged pattern of climate change that occurred as humans were first evolving, and made their habitats more prone to wildfire. Early humans may then have learned to exploit the increasingly common fires around them for cooked meals and other benefits, researchers say.
Humans are the only animals known to create and control fire. This has not only helped people stay warm, see in the dark and practice metalworking; much research suggests it influenced the shape of the human body itself. For example, cooking makes it easier to chew and digest many foods, and analyses of reductions in tooth and jaw size suggest that human ancestors may have learned how to cook as early as nearly two million years ago.
