相互竞争的假说认为，原始灵长类动物起源于非洲、印度次大陆或东亚，尽管最早明确确定的原始灵长类动物主要来自欧洲和北美。最近我们报道了中国始新世早期发现的Teilhardina asiatica。这一发现构成了来自亚洲的最古老的明确的灵长类动物，代表了已知最原始的omomyid。这一发现表明，欧洲和北美的异形虫很可能起源于亚洲，并为原始灵长类动物的亚洲起源假说提供了新的线索。不能排除在中国南方发现形态上更广义的真灵长类（或原真灵长类）的可能性。
Competing hypotheses maintain that euprimates originated in Africa, the Indian subcontinent, or East Asia, although the earliest unequivocally identified euprimates have been recorded mainly from Europe and North America. Recently we reported the discovery of Teilhardina asiatica from the earliest Eocene of China. This discovery constitutes the oldest unambiguous euprimate from Asia, and represents the most primitive known omomyid. It suggests that European and North American omomyids were probably rooted in Asia, and casts new light on the Asian-origin hypothesis of euprimates. The possibility of finding morphologically more generalized euprimates (or proto-euprimates) in southern China cannot be dismissed.
