About This Book

The author surveys fossil evidence for primordial life preserved in the oldest rock formations, tracing the chain of life backward through Cambrian, Precambrian, and Laurentian strata. He describes and analyzes key specimens, including stromatolitic and calcareous remains, and combines microscopic study with field observations to interpret their form and affinities. Chapters examine geological settings and preservational processes that enable organic traces to survive, while appendices review technical debates and criticisms surrounding identifications. The work weighs competing hypotheses about the origin and early evolution of life and proposes directions for further investigation.

Transcriber Note

In order to accommodate placement of illustrations and footnotes, many paragraphs were split where it seemed reasonable. Minor typos were corrected. A web search shows that the anchorless Footnote on page 139 appears to reference the quoted text on page 140. Therefore, the Footnote was placed after the quoted text.

On page 174, Footnote 36 referred twice to Figure 8 and to a "Microscopic slice" as Figure 61 which does not exist. It is assumed the intent was to refer to Figures 7, 7a, 8 and 59 and has been altered to point to those figures. The caption for Fig. 7 also refers to "Fig. 61, p. 310" and has been updated to "Fig. 59, p. 237".
