The so-called alien skeletons on display earlier in September at Mexico's first public congressional hearing on Unidentified Anomalous Phenomena (UAPs) showed no signs of assembly or manipulation, according to doctors.
The scientists performed several tests on the two unusual specimen with procedures that were live-streamed on Jaime Maussan's YouTube channel.
José Zalce Benitez, the director of the Health Sciences Research Institute in the secretary of the Mexican navy’s office, concluded that the alleged alien skeletal remains were all once connected naturally and not pieced together by potential hoaxers.
Benitez added that his team found that one specimen “was alive, was intact, was biological and was in gestation." He suggested that large lumps inside the alleged alien's abdomen could be eggs.
“I can affirm that these bodies have no relation to human beings,” he said previously.
The purported bodies, which were reportedly unearthed in Cusco, Peru, in 2017, feature elongated heads and three fingers on each hand.
Despite those factors, the bodies appear similar to that of a human being, with two arms and two legs each.
According to Maussan, the bodies featured strong, light bones but no teeth. They also had implants of cadmium and osmium, elements that are very scarce on Earth.
“These specimens are not part of our evolutionary history of Earth,” Massaun told Mexican government officials and representatives from the US, according to the New York Post. “They are not beings recovered from a UFO crash. Instead, they were found in diatom (algae) mines and subsequently became fossilized."
“This is the first time [extraterrestrial life] is presented in such a form, and I think there is a clear demonstration that we are dealing with non-human specimens that are not related to any other species in our world."
Maussan, who presented the specimens under oath last week, claimed that they were found in diatom (algae) mines, and later fossilized. He insisted emphatically that the two objects were not part of "our terrestrial evolution."
However, there has been plenty of skepticism of the alleged alien bodies.
Fierro pointed out that some of the details surrounding the specimens "make no sense," and noted that the university does not support the findings.
She also noted that further tests, beyond an X-ray, would be necessary to ascertain if the beings were actually non-human.
A panel of experts assembled by Alexander Sokolov, from the Scientists Against Myths YouTube vlog suggested the alleged aliens were a mere hodgepodge of human and animal bones strung together.

Physics professor Brian Cox is also among the skeptics, saying last week that it's "very unlikely that an intelligent species that evolved on another planet would look like us."
This debate over the alleged alien bodies comes hot on the heels of a report that the National Aeronautics and Space Administration (NASA) announced that it is poised to release its official stance on extraterrestrial life, UFOs and aliens.
Their findings, according to an earlier Knewz.com report, will be based on 800 alleged sightings and subsequent reports spanning 27 years. NASA, not privy to the Pentagon's secrets, has been known to debunk reported UFO sightings rather than support them.
