Human development greatly depends on climatic conditions. There is a 50,000-year-old record of the human body, which shows that the human brain has already shrunk by 10 percent. Jeff Morgan Stibble, a scientist at the Natural History Museum in California, studies how humans cope with a changing climate.
In his study paper, he writes that it is not easy to understand the effect of climate change on the human brain. Although its brain is shrinking and getting smaller. This is affecting their behavior as well. This study has been done on the brains of 298 humans. These are fossils of the brain of ancient humans, which are from 50 thousand years ago. This was compared by adding to the rainfall and heat data.

The study is published in the journal Brain, Behavior and Evolution. It has been found that the average brain size tends to decrease when the weather is hot, while it tends to increase in winter. According to Jeff Morgan, the human mind changes from time to time. Jeff said that while the brains of many species have evolved over the past few million years, the reverse is happening with humans. 373 measurements of 298 human skulls have been examined, as well as the climate of the geographic location where they were found. It was calculated according to the season by dividing it into different year categories.
Brain has become 10 percent smaller, is it due to global warming
