The Neanderthal Connection: Morning People Inherited Faster Body Clocks

A new study suggests that being a morning person may be linked to Neanderthal ancestry. Researchers analyzed Neanderthal DNA in modern human genomes and found that certain genetic variants associated with circadian genes were more prevalent in individuals who tend to be morning people. This adaptation likely provided an evolutionary advantage for early humans living in regions with shorter winter days and scarce food resources. While being a morning person is not solely determined by Neanderthal genes, further research will explore the effects of these genetic variants on other adaptive traits.

Ancient Genome Sequences Reveal Europe's Earliest Settlers

Researchers have sequenced the genomes of ancient modern humans from the Buran-Kaya III site in Crimea, dating back 36,000 to 37,000 years. The study reveals that these individuals had recent Neanderthal ancestry, suggesting interbreeding between modern humans and Neanderthals in Europe during the Upper Paleolithic period. The findings contribute to our understanding of the genetic history and interactions between different human populations during this time.

"Scientists Reveal Face of Oldest Human Ever: A Glimpse into Life 45,000 Years Ago"

Scientists have used a digital model of a broken skull to reveal the face of what may be the oldest human to have lived, a woman who lived 45,000 years ago. The fossilized remains, found in Czechia, are only a portion of the skull, as researchers believe she was consumed by an animal after death. Using recorded measurements and reference images, the international team of academics recreated her face, revealing her dark features. The woman, known as Zlatý kůň or golden horse, was among the first Homo sapiens to live in Eurasia after our species migrated out of Africa and carried about three percent Neanderthal ancestry.

"Unveiling the Remarkable Resemblance of Zlatý kůň, the World's Oldest Genetically Sequenced Human"

A facial approximation of the Zlatý kůň woman, the oldest modern human to be genetically sequenced, has been created using data from computed tomography scans of her skull. The woman lived 45,000 years ago and her genome carries roughly 3% Neanderthal ancestry. The facial approximation reveals a woman with dark, curly hair and brown eyes, and a robust jawline that is more compatible with Neanderthals than modern humans. However, much about her remains a mystery, and the approximation provides only a speculative representation of her soft tissues.

"Unveiling the Remarkable Resemblance of Zlatý kůň, the World's Oldest Genetically Sequenced Human"

Researchers have created a facial approximation of the Zlatý kůň woman, the oldest modern human to have her genome sequenced. The woman lived 45,000 years ago and her DNA revealed that she had roughly 3% Neanderthal ancestry. Using existing CT scans of her skull and statistical data, researchers reconstructed her face, noting her robust jawline and larger endocranial volume compared to modern humans. The lifelike image depicts a woman with dark, curly hair and brown eyes, providing insight into her possible appearance. However, much about her remains a mystery, as genetic data cannot accurately determine facial characteristics.
