Kapangidwe kameneka, kamene kamakhulupirira kuti ndi chimodzi mwa zida zakale kwambiri zopangira anthu ku Europe, adamangidwa ndi osakasaka a Stone Age.

Zaka 10,000 zakale zodabwitsa zomwe zidafukulidwa pansi pa Nyanja ya Baltic 1. — Mtundu wa 3D wa gawo lalifupi la mwala wa miyala monga momwe likuwonekera pansi pa Nyanja ya Baltic. Ngongole ya Zithunzi: Philipp Hoy, University of Rostock / chitsanzo: Jens Auer, LAKD MV

Tangoganizani mzere womwe ukutambasula pafupifupi kilomita imodzi kudutsa pansi pa nyanja - uku ndiko kukula kwa zinthu zodabwitsazi. Anatchedwa "Blinkerwall" ndi ofufuza, ndi miyala pafupifupi 1,500 ndi miyala yokonzedwa bwino motsatana. Khoma la pansi pamadzi ili silinamangidwe kuti lizikongoletsa; akukhulupirira kuti adathandizira kwambiri moyo wa alenje.

Zaka 10,000 zakale zodabwitsa zomwe zidafukulidwa pansi pa Nyanja ya Baltic 2. — Undersea morphology ya dera, yosonkhanitsidwa pogwiritsa ntchito galimoto yakutali. Mu chithunzi chachitatu, mivi yoyera imaloza ku Blinkerwall. Ngongole ya Zithunzi: Geersen et al., PNAS (3)

Nanga bwanji? Ofufuza akuganiza kuti inali imodzi mwa njira zosaka nyama. Mpweya, zomwe zinali chakudya chambiri kwa anthu oyambirirawa, ziyenera kuti zinkawetera kukhoma. Mzera wa miyalayo uyenera kuti unkakhala ngati chotchinga kapena chotchinga, zomwe zinapangitsa kuti alenje azitha kupha nyama zawo mosavuta.
