The controversy over Atacama & # 39; Alien & # 39; deepens



LONDON – A mysterious 6-inch skeleton found in Chile's Atacama Desert has puzzled scholars and audiences since its discovery more than a decade ago.

With its tiny stature and features that both human and somehow do not appear, many speculated that the abandoned mummy might be extraterrestrial.

A study published this year seemed to finally lift the case after the researchers carried out skeletal and genomic analysis on the remains, concluding that "ata" is actually a human girl with genetic abnormalities, including "accelerated Bone Aging "

However, research encountered immediate backlash as many questioned the findings and ethics of the study itself.

A new effort led by an international team of researchers is now questioning the work, claiming that the genome analyzes are unjustified and that the skeleton, at about the 1

5-week point, is actually that of a typically developing fetus ,

The mysterious Mum y, nicknamed Ata, was found in 2003 in the Atacama Desert and eventually landed in the hands of a Spanish collector before it became the subject of a documentary and later studies by Stanford University researcher Garry Nolan [19659002] The latest study, published last March in the journal Genome Research, sparked such an immediate debate that the authors, including Nolan, published a statement just days later.

According to the Chilean government and scientists criticizing the work the skeleton was illegally brought out of the country, and the subsequent studies should never have been carried out.

A new study questions research even more, citing concerns about both ethics and skeletal and genomic analyzes There was no scientific rationale for performing genomic analyzes of Ata, as the skeleton is normal, It is known that oncology patients are strongly associated with skeletal pathologies that would affect the skeleton at that age, "says Prof. Sian Halcrow of the University of Otago for bioarchaeologists.

This case study shows how experts from osteology and medicine come together Archeology, history and genetics are essential for accurate scientific interpretations and for taking into account the ethical implications of genomic analysis.

A nuanced understanding of skeletal processes and kultu It is essential for accurate scientific interpretation and control of the ethics and legality of such research.

The international team broke off previous research on a series of seemingly problematic issues surrounding the methods and claims of age, development, and related mutations of the skeleton.

The authors, for example, pointed out the fact that Ata However, as the new study finds, these so-called "floating ribs" may not yet have started at this stage.

It also casts doubt on the seemingly "elongated skull." "and argues that it seems normal for a liberated preterm infant."

"Taken together, none of the methods or findings presented by Bhattacharya and colleagues regarding Ata's skeletal age fulfill the standards accepted for age /stern/magazin/…0/index.html […] biographical, forensic or pediatric / obstetrical technique, "argue the authors of the ne work.

Researchers report that these are likely to be miscarriages that may date from the recent past. 19659002] "This mummy is a sad loss to a mother in the Atacama Desert," says Dr. Bernardo Arriaza, bioarchaeologist of the University Tarapacá in Chile.

The controversy raises important questions about the ethics of the archa on eological and genomic research, especially in situations where the legality of the samples is unclear.

"We caution DNA researchers against engaging in cases where the context and legality are not clear or the remains are left in private collections," says Halcrow
