I read about this in another thread but I couldn't find an explanation for it, Does anyone know where it may have came from?

A lack of ancient samples from both Libya and Tunisia make that question hard to answer, it will be interesting to see the admixture results of ancient Libyans if they had some sort of proto natufian component.

I believe this admixture drove in from Eastern Maghreb to western Maghreb. I’ll have a little look over the paper again and see if we have an explanation for it.

Consistent with previous results, when Taforalt, KEB, and Guanches (f3 = 0.2196) are excluded, IAM shares more drift with ancient Levantine populations, such as Epipaleolithic communities (Natufians; f3 = 0.2296) and Pre-Pottery Neolithic individuals (f3 = 0.2167) (Fig. 3 and SI Appendix, Supplementary Note 10), than with any other ancient population. This confirms previous results for Taforalt (17) indicating a Levantine intrusion in North Africa in Paleolithic times.
