At a glance
- A new archive of ancient human brains has been created by UK researchers, providing insights into early human evolution and ancient diseases.
- The brains in the collection date back up to 12,000 years old and were found in various sites worldwide, representing a rare soft tissue preservation.
- Preserving entire organs, like brains, without deliberate intervention is unusual, making this archive a significant discovery.
- Researchers have uncovered patterns in environmental conditions associated with brain preservation, shedding light on the biomolecules preserved in these ancient brains.
- The emergence of language around 1.6 million years ago in eastern or southern Africa played a crucial role in human evolution, enabling early humans to survive and colonize the world.
The details
A new archive of ancient human brains has been created by UK researchers, providing valuable insights into the early evolution of humans and ancient diseases.
The collection includes samples from Egyptian and Korean royalty, British and Danish monks, Arctic explorers, and war victims, with many of the brains dating back up to 12,000 years old.
These brains were found in various sites such as Stone Age Sweden, an Iranian salt mine, and Andean volcanoes, representing a rare preservation of soft tissue in the geological record.
The preservation of entire organs like brains is unusual without deliberate intervention such as embalming or freezing, making this archive a significant discovery.
The brains offer researchers the opportunity to analyze the early evolution of humans, challenging the rarity of brain preservation among skeletonized remains.
A new study published in the Proceedings of the Royal Society B highlights the importance of this archive, representing the largest study of archaeological literature on preserved brains to date.
Researchers have uncovered patterns in environmental conditions associated with preservation modes, revealing more than 1,300 brains as the only soft tissues preserved.
The oldest brains in the archive date back to the last Ice Age, with the mechanism of preservation for these ancient brains remaining unknown.
Proteins and fats fusing in the presence of elements like iron or copper may play a role in the preservation of nervous tissues, shedding light on the biomolecules preserved in these brains.
By exploring these ancient biomolecules, researchers aim to learn more about the lives and deaths of our ancestors.
In a separate study, British archaeologist Steven Mithen suggests that early humans developed rudimentary language around 1.6 million years ago in eastern or southern Africa.
This challenges previous beliefs that humans only started speaking around 200,000 years ago, with evidence suggesting that the birth of language occurred between two and 1.5 million years ago.
The increase in human brain size from 2 million BC, coupled with the evolution of structures like Broca’s area in the brain, contributed to the development of speech.
The emergence of bipedalism and changes in the human skull shape around 1.8 million years ago also played a role in the evolution of language.
The language was crucial for group planning and coordination in hunting large animals, enabling early humans to survive in different ecological and climatic zones.
The birth of language marked the beginning of linguistic development, with some aspects of the first linguistic development 1.6 million years ago potentially surviving in modern languages.
This linguistic development allowed humans to colonize the world around 1.4 million years ago, demonstrating the significant impact of language on human evolution and civilization.
