Life's Dawn on Earth Being the history of the oldest known fossil remains, and their relations to geological time and to the development of the animal kingdom

"Life's Dawn on Earth" by John William Dawson tells the story of a groundbreaking discovery in the world of paleontology. It centers around Eozoon canadense, an ancient fossil found in Canada that was believed to be one of the earliest forms of life on Earth. The book highlights the excitement and debate that followed its discovery, challenging old assumptions that the Laurentian rocks were lifeless, capturing how this fossil offered a glimpse into the very beginnings of animal life and how it connects to geological time-frames and the overall story of the animal kingdom's development. Dawson wrote the volume to share the details of Eozoon within its geological time frame to reach scientists and general readers who were curious about how life first emerged on Earth to educate them about Earth's biological past.
