Climate change changes people's creativity

The Live Science website said on May 21 that there was evidence that the favorable climate period was also when humans invented new tools, and began to use symbolic images, the foundation for writing.

Studies show a close relationship between climate change and changes in human progress.

'We provide the first evidence of the emergence and disappearance of human-related innovations in climate change,' said study author Martin Ziegler, a scientist on Earth. at Cardiff University, Wales, said.

Prior to this stage of development, humanity was still in a rather primitive state, with the main tools being made available from nature, not yet sophisticatedly built, Ziegler said. But during the wet and humid periods of abundance, more modern tools of bone and stone appeared, along with pictures of symbols appearing on the walls of the cave, showing that there was development. language.

Archaeologists also found the first evidence of the cultivation areas built during this period, along with shellfish used as jewelry, Ziegler said. The stages this study covers are about 71,000 years ago and another period between 64,000 and 59,000 years ago.

In the study, Ziegler recreated the climate in South Africa in the last 100,000 years. They collected data by analyzing fossil samples in the southernmost tip of Africa to understand climate change. Chemicals in fossils show regional rainfall over time, according to Ziegler, as well as other weather indicators.

The general analysis showed that during this lush and wet period in South Africa, the rest of the sub-Saharan region suffered from severe drought, while the Northern Hemisphere was very cold, Ziegler said. Research shows that it is related, but not necessarily, the causal relationship between wet weather and human creativity. It may also be during this period that the drought in North Africa has pushed more people to the south.

The study was published in Nature Communications magazine on May 21.
