Historical environmental change in Africa drives divergence and admixture of Aedes aegypti mosquitoes: a precursor to successful worldwide colonization? por Bennett, K.L., Shija, F., Linton, Y., Misinzo, G., Kaddumukasa, M., Djouaka, R.F., Anyaele, O., Harris, Angela, Irish, S., Hlaing, T., Prakash, A., Lutwama, J., Walton, C.

“…As ancestral Ae. aegypti were dependent on forests, this population history is consistent with the effects of forest fragmentation and expansion driven by Pleistocene climatic change. Alternatively, or additionally, historical human movement across the continent may have facilitated their recent spread and mixing. …”
