Can someone TL;DR? What does this mean? It just made me think, whether it's related or not, shouldn't the "natural" resting position of human heads be "upwards" like the rest of the animal world? I mean if you consider the worm/fish template, it's
where "o" is the "tail end" and ">" is the head. It points in the "direction" of the body. All other mammals and birds are also
whereas we weirdos are

No. We’re talking about axial twist that occurred very early in vertebrate evolution. The hypothesis aims to explain why each brain hemisphere is associated with the opposite side of the body, including the eyes, in vertebrates (but not in invertebrates). |
