Bizarre skeletal remains with just three fingers and three toes could be alien - despite having many similarities to humans, it is claimed.
The mysterious remains, which were found in Peru alongside a nine-month-old baby mummy, have been named Maria by a research team.
Tests reportedly reveal that Maria is humanoid - because she does have 23 chromosomes - but she does have a number of things that mean she is not human.
Professor Konstantin Korotkov, from the Russian National Research University says he has also seen four other male mummies found by colleagues in Peru, which date back as far as 6,500 years.
He told Sputnik News: "Each of the little mummies has two arms, two legs, a head, a pair of eyes and a mouth.
“Tomographic scans reveal their skeletons.
“The tissue has biological nature and their chemical composition indicates that they are humans.
“Their DNA features 23 pairs of chromosomes, just like we have.
“All the four of them are males, each with a Y-chromosome.
"They appear human but they are not.
“Their anatomic structure is different.”
The team researching Maria's remains have been investigating since last year.
Conspiracy theory website Gaia.com has featured videos suggesting the discovery could be a being closely related to humans and still from outer space.
And professor Korotkov appears to agree: "They could be extraterrestrials or bio robots.
"Maria and [baby] Vavita could have been representatives of a certain race which had possibly reached a stage of advancement much earlier than we did.
"Maybe thousands of years earlier.”
