WebIt is possible that the Makganyene glaciation played a role in the evolution of eukaryotes and the Marinoan glaciation in the achievement of multicellularity in (microscopic) animals. However, the fossil record provides no support for close correlations in time and causal links are entirely speculative. Webglaciation in the Proterozoic appear correlated with significant changes in the evolution of life (8, 12–14) and atmospheric oxygen level (15–19). The Paleoproterozoic Makganyene glaci-ation occurred approximately between 2.3 and 2.2 Ga, and at least two other low-latitude glaciations occurred during the http://snowballearth.org/when.html the color kapper
