The cemetery of the ancient Nazca people is located at the Jauranga archaeological site in the Palpa Valley, in the Ica region of southern Peru.
Lars Fehren-Schmitz, an anthropologist from the University of California, stated in his statement to the science news-focused Live Science platform that the skeleton of a baby suffering from cyclopia (one-eyedness) was found in the cemetery of the ancient Nazca people in the Palpa Valley of Peru, a South American country.
Fehren-Schmitz stated that in DNA analysis, it was determined that the baby who lived approximately 1600 years ago carried an extra copy of the 13th chromosome.
During the examination of the skeleton, it was determined that there was a single eye socket in the middle of the face of the baby's skull. As a result of genetic analysis, it was determined that the chromosomal anomaly known as trisomy 13 was the possible cause of this birth defect.
Fehren-Schmitz said that they could not obtain definitive information about how long the baby lived.
Monocularity is known as a rare birth defect in which a single eye socket is formed in the middle part of the face as a result of the embryonic forebrain (prosencephalon) not being properly separated into the right and left hemispheres during early pregnancy.

Researchers from Canada, Thailand and France discovered a giant rodent species called 'Yakamys sirindhornae', weighing 30 kg, that lived 34 million years ago in the Krabi region of Thailand. The finding offers new insights into the evolutionary history of large rodents.

Physicists from the University of New Hampshire have developed a new gravitational model called 'MAGIC' that prevents time travel paradoxes. Offering an alternative to Einstein's theory, the model provides a new perspective on the mechanisms of preserving the time fabric of the universe.

Researchers at the University of Sao Paulo determined that cats developed the act of meowing as a means of communication towards humans. In the experiment conducted with 38 cats, it was observed that the rate of cats meowing in the presence of humans increased 16 times and they made eye contact.
