Creative research and development, tell me how to write.

For a long time, scientists have always believed that it was not until 40 thousand years ago that early humans began to break through the unchanging mindset. However, archaeological discoveries in recent years reveal that our ancestors were already generating the fire of wisdom before this. As early as hundreds of thousands of years ago, human creativity was promoted by biological and sociological factors.

From the Mona Lisa and Mozart's famous songs to the spacecraft on the launch pad of NASA, this only shows a small part of the long history of human creation-human beings have the ability to create new things and constantly improve their designs and skills. "Modern humans are extraordinary inventors, and our skills are getting higher and higher." Christopher Henhilwood, an archaeologist at the University of Witwatersrand in South Africa, said.

How do we get this seemingly infinite creativity? This is a hot spot in scientific research. We don't always have such keen creativity. Although humans appeared in Africa about 6 million years ago, in the first 3.4 million years, there were few visible new inventions left by early Terran members. Sometime later, migrants began to hammer pebbles with stones in the water to make cutting tools. There is no doubt that this is an ingenious invention, but it is followed by a long bottleneck period-there are few inventions in this period. Our distant ancestors used the same stone axe10.6 million years, and the improvement was extremely limited. "These tools are really out of date." McBree Atind, an archaeologist at the University of Connecticut, said.

So, when did the human brain begin to produce some innovative ideas in science and technology and art? Until recently, most researchers believed that 40,000 years ago, when mankind just entered the late Paleolithic period, Homo sapiens triggered a sudden upsurge of invention in Europe-fashionable shell necklaces, exquisite murals painted with European bison and other ice age animals on the cave walls, and a series of new stone and bone tools. These findings promoted a popular theory, that is, random gene mutation at that time made a sudden leap in human cognition and ignited a "great change" in innovation.

However, some emerging evidences question the catastrophe theory. In the past ten years, archaeologists have unearthed a series of ancient evidence that art and advanced technology exist (of course, the advanced technology here is relative), which shows that the time for human beings to produce innovative ideas is much earlier than we expected: even before Homo sapiens appeared, that is, 200,000 years ago, the human brain had this ability. However, although our innovative ability appeared very early, it took thousands of years to be transformed into the fire-making ability in Africa and Europe. These evidences reveal that our innovation ability did not suddenly erupt in the late stage of human evolution, but only appeared after hundreds of thousands of years of accumulation and a series of complex biological and sociological factors.

When did mankind start to break through the conventional thinking, and what factors finally ignited the fire of human wisdom? To answer this question, we need to grasp several key clues like reading detective novels, and then start this exploration journey from the clues that show the origin time of human creativity.
