Saxitl

The inhabitants of Yalhuaca are descendants of Homo Sapiens, and are known as Homo Yalhuacensis, or the Saxitl. They have evolved to eat a largely, if not entirely, herbivorous diet consisting mostly of agriculture and foraged goods. With a longer intestinal tract and ability to absorb vitamin B12 from the large intestines in a way similar to many ruminants, though significantly less efficiently. Fermented foods and mushrooms are important to the diet of Homo Yalhuacensis because they provide necessary B12, vitamin D and other vitamins that can be difficult to otherwise get without animal products. Large livers store B12 when it is consumed, so an average Saxitl will not be deficient in any of these nutrients. Some smaller differences include bright blue eyes that can see very well in the dark, and taller height (average 5'8 for females, 6'0 for males). They live on average around ~95 years.

The two main groups of people are the Interior Sixatl and the Coastal Sixatl.

The Coastal Sixatl live in generally cloudier and shadier regions lining the coast, and are better equipped for wet conditions and require a lot of water to survive. They are somewhat more equipped for omnivory. Due to less direct light from the top, they have wavy or slightly curly hair.

The Interior Sixatl live in generally sunnier and less shady regions in the interior western savannah and forest. They have significant adaptations for low water conditions and are more geared toward total herbivory. They have very curly hair to protect their scalps from the sun, and epicanthic folds which historically protected against sandstorms when that was more common.
