Consequently, it is argued the species represents a unique ontogeny unlike any extant ape. 18. Scientific studies have focused on their ontogeny , biomechanics and ecology, among other subjects. 19. One big point of discussion with regard to the claustrum has been on the ontogeny . 20. Luttrell ( 1951 ) studied ascomal ontogeny and hamathicial development in " Glonium stellatum"
