A illustration of how Retrogrades are created.
Returners to Ancestry or "Retrogrades" are rare Madararui that are born from two ape-men with Madararui ancestors. When Ape-Men have a child (even with a Madararui), it comes out as an Ape-Man, bu when there is a Madararui in previous generation, occasionally a non-monkey (Madararui) is born. That is a Returners to Ancestry or Retrograde. They can have Madararui children while retaining a monkey's fertility, because they are Madararui with monkey characteristics. Kunimasa calls them "the most rare of the rare. The premium."
