According to the scientific consensus, in the last 6 million years, the size of the human brain increased roughly three times in parallel with the appearance of various new, increasingly complex activities, and then reached its maximum 10-15 thousand years ago, which is considered yesterday in the evolutionary time scale.

The organ's size has actually held steady over the past 300,000 years, according to new research that reassessed data on brain evolution.

The 12th century BC, when humans were forging great empires and developing new forms of written text, did not coincide with an evolutionary reduction in brain size.

Did the 12th century B.C.E. -- a time when humans were forging great empires and developing new forms of written text -- coincide with an evolutionary reduction in brain size? Think again, says a UNLV-led team of researchers who refute a hypothesis that's growing increasingly popular among the science community.

Last year's study was sharply criticized by a team of scientists from UNLV, who found many ambiguities in it.

New research has demolished previous theories about evolution, as researchers find that human brains did not shrink 3,000 year ago.

In previous research released in Frontiers in Ecology and Evolution, experts asserted that the human brain shrank amid a transition to modern urban societies nearly 3,000 years ago.

It happened on Monday, July 25, 2022. Alerted by a visitor, park rangers from the Lake Mead Ecological Reserve found 25 human bodies in the bed of the main lake in the protected natural area. Due to extreme drought, which has plagued the United States for at least five years, the drops in the water level has reach historic lows. In response, local authorities stated that, "they are on site and have established a perimeter to recover remainds."

A third set of human remains were found in Nevada's Lake Mead on July 25 as water levels have receded to historic lows during a drought fueled by climate change.

The remains were spotted by a witness at Swim Beach on Lake Mead during the afternoon of July 25, the National Park Service announced. Investigators retrieved the remains, the park service said. They are at the least the third set of remains found as the drought-stricken reservoir, which supplies water to 25 million people across the Southwest, has receded to unprecedented levels.
