The rarity of bipedalism and the specific anatomical traits observed in UFO occupants suggest they are part of the hominin lineage rather than evolved from other planetary life forms.

“based on the definition of a hominin an upright walking primate we in the primate order we stand up on two limbs we're not only the only primate that does that we're the only mammal on this planet that habitually walks on two limbs”

Human biology and parental roles evolved to favor group-based care, meaning children thrive when they have multiple inputs beyond just the mother.

“The reason why human fatherhood evolved is because children evolved to be brought up by a group of people. And part of that group of people was a father figure.”

Close evolutionary relationships between species do not guarantee similar social behaviors.

“one of the things your work highlights and this has been the case with other primatologists particularly more recently is that because you just mentioned that species that are even very closely related can have radical differences in their fundamental behaviors”

Ancient indigenous oral traditions often contain vital kernels of truth regarding history and pre-history.

“oral tradition a lot of times ends up being correct so oral tradition and this case alludes to some kind of acid being used to build structures”

Indigenous societies possessed a rhetorical and social structure that effectively criticized European materialism and lack of freedom.

“they seem to have a governance they seem to have a very rhetorical governance structure and it's all sunshine and rainbows but you can also look through the history and be like okay well the the Inca the Aztec the Maya these are all really bloody brutal societies”
