从常染色体上看北非、南非的现代人起源主要是“连续进化附带杂交”还是“东非起源”？

阿特拉斯山脉以北的北非沿海和南非西南部在冰河时代一直与热带非洲之间存在地理隔离。那么从常染色体上看，北非、南非的现代人起源主要是“连续进化附带杂交”还是“东非起源”？旧石器时代晚期古老型人类在北非、南非的残存情况如何？是否存在像纤细型南猿在南非一直和能人并存到200万年前这样的情况?

北非南非东非的现代人并非一个时空上的单一种群，最早留存的种族可能是科伊桑人，班图人强大起来后，科伊桑人被挤压到南非博茨瓦纳一带，科伊桑人很可能与东亚人的起源有关联。

北非沿海直到1.5万年前西亚R1b群体进入前的2万年前，都还生活着比同时期欧洲人更像尼人的土著居民。

我感觉还是“连续进化附带杂交”的观点更靠谱一些。

Although modern populations in the Maghreb speak languages belonging to the Afro-Asiatic family, which is associated with the Capsian culture, it has been hypothesized that the Capsians' predecessors, the Iberomaurusians, may have spoken a language(s) from a different phylum. This was inferred from the likelihood that the Iberomaurusians existed prior to the advent of the Proto-Afro-Asiatic language, as well as from the presence of what appears to be an older, pre-Afro-Asiatic population substratum in parts of the Atlas Mountains.
