Study finds human brains did not shrink 3,000 years ago



  • Largely accepted concept is that size of human brain changed 3,000 years ago.
  • It is posited that group thinking caused brain to shrink.
  • New paper refutes concept, says human brain remained “remarkably stable over last 300,00 years”.

Refuting a common and largely accepted concept, a new paper published in Frontiers in Ecology and Evolution argues that the size of the human brain did not change 3,000 years ago — or ever, for that matter.

Anthropologist Brian Villmoare from the University of Nevada and scientist Mark Grabowski of Liverpool John Moores University have responded to a paper by Jerome DeSilva of Dartmouth College and colleagues in 2021.

The 2021 paper suggested that in the Iron Age, the human brain lost up to 150 cubic centimetres of its volume, which is nearly the size of a lemon. 

DeSilva’s team posited that “self-domestication” and more group thinking than individual thinking caused the brain to shrink.

While DeSilva’s study analysed 10 million years of evolution including apes, Villmaore said that it was useless and pointless to compare sapiens’ brains to any other species.

One reason was the lack of sufficient fossils of other human species. The author explained that we have been entirely different species.

Villmaore told Haaretz they doubted the statistical treatment of data in DeSilva’s paper. Therefore, the no shrinkage study used the same data as they found it “the most complete”. 

However, their statistical methodology was different and so were their conclusions, eventually.

“The point was that we need to toss all this stuff about human devolution out,” he said. “It is just not true.”

Their study concluded that the size of the human brain had remained “remarkably stable over the last 300,00 years” and that shifting to agriculture and community did not affect brain size.

Responding to DeSilva comparing ants and human societies saying that collective intelligence reduced size in both the clades, the no shrinkage paper pointed out differences between the two.

Villmaore said that humans were a competitive species, unlike ants who are mostly just slaves. Vertebrae, he said, make alliances, are aggressive, social and have larger brains.

He said that we could compare elephants and rhinos as the former live in herds while the latter does not.

“The elephant brain is six times bigger than that of the rhino,” he said.

He also pointed out another flaw. He said that DeSilva said that the shrinking occurred globally while tying it with the agricultural revolution.

However, this revolution would have taken place at different times in different parts of the planet. This does not explain all human brains shrinking in the world.

TikTok plans to introduce an image search capability in order to directly compete with Google.




TikTok, a Chinese short video platform, is now conducting a trial of a novel functionality that enables users to capture or submit images in order to discover comparable products within the TikTok Shop, as reported by TechCrunch.

TikTok, the current leader in social media, is now aiming to enter Google’s domain in the field of search, indicating a direct competition against Google’s control in visual search.

The functionality, originally observed by user Jonah Manzano, is presently accessible to users residing in the United States and Southeast Asia. Users that have access to the feature will see a camera symbol that is integrated.
This feature allows users to effortlessly search for products by capturing or uploading photographs, eliminating the requirement for written descriptions.

For example, if you are eating at a restaurant and like the dish that is presented on a certain plate, you can take a fast photo using the TikTok app to discover comparable goods that you can buy.

Similarly, if you come across an expensive item while shopping online, you can save its image and use TikTok’s image search feature to locate similar, more affordable options.

Although TikTok Shop has previously utilized conventional search methods, this new advancement represents a notable deviation by harnessing the capabilities of visual search, similar to Google Lens.

TikTok’s decision is a calculated maneuver aimed at not only attracting users’ interest in finding new products but also promoting sales within its e-commerce network.

This development is not only a criticism of Google or Amazon; it is a more extensive effort to rival other participants in the field of visual search and e-commerce, such as Klarna and rising businesses like Cherry.

TikTok’s shift towards e-commerce is apparent in its recent announcement that TikTok Shop accommodates more than 15 million vendors worldwide, including a significant presence in the United States.

The company has made significant investments in platform safety, dedicating more than $400 million and establishing a staff of 7,500 personnel to guarantee the integrity of TikTok Shop.

TikTok continues to pursue its e-commerce goals, while encountering regulatory obstacles, especially in the United States.

TikTok’s momentum remains unaffected by President Biden’s recent measure, which indicates a possible prohibition if ByteDance does not divest the platform.

However, the corporation regards e-commerce as a strategic source of income and a method to maintain consumer involvement within its ecosystem.

TikTok is continuously expanding and improving its TikTok Shop to encourage more user interaction and spending. This will help establish TikTok as a strong competitor in the e-commerce industry.
