Precambrian micro‐organisms and evolutionary events prior to the origin of vascular plants

TLDR: The nature of the early Palaeozoic life was a fertile subject for speculation as mentioned in this paper, however, evidence of this development remained largely undeciphered ; the nature of Precambrian life was also fertile subject to speculation.

Abstract: The nature of the Precambrian biota-its antiquity. composition and evolutionand the well-known faunal discontinuity near the beginning of the Palaeozoic. have long been recognized as particularly puzzling problems in palaeontology . The evolutionary continuum well-documented in Phanerozoic sediments and the diversity and complexity of the early Palaeozoic biota augur well for a substantial period of Precambrian evolutionary development . Until recently. however. evidence of this development remained largely undeciphered ; the nature of Precambrian life was a fertile subject for speculation. essentially unfettered by the poorly known fossil record . The past few years have witnessed a renewed interest in these classic problems and a marked proliferation of available data; this increased activity has resulted in the
