Origin of Life: "For at least three-quarters of the book of ages engraved in the earth’s crust the pages are blank." - The World We Live In
"The initial steps . . . are not known; . . . no trace of them remains." - Red Giants and White Dwarfs
Many-Celled Life: "How many-celled animals originated and whether this step occurred one or more times and in one or more ways remain difficult and ever-debated questions that are . . . 'in the last analysis, quite unanswerable.'" - Science
"The fossil record contains no trace of these preliminary stages in the development of many-celled organisms." - Red Giants and White Dwarfs
Plant Life: "Most botanists look to the fossil record as the source of enlightenment. But . . . no such help has been discovered. . . . There is no evidence of the ancestry." - The Natural History of Palms
Insects: "The fossil record does not give any information on the origin of insects." - Encyclopædia Britannica
"There are no fossils known that show what the primitive ancestral insects looked like." - The Insects
Animals With Backbones: "Fossil remains, however, give no information on the origin of the vertebrates." - Encyclopædia Britannica
Fish: "To our knowledge, no 'link' connected this new beast to any previous form of life. The fish just appeared." - Marvels & Mysteries of Our Animal World
Fish Becoming Amphibians: "Just how or why they did this we will probably never know." - The Fishes
Amphibians Becoming Reptiles: "One of the frustrating features of the fossil record of vertebrate history is that it shows so little about the evolution of reptiles during their earliest days, when the shelled egg was developing." - The Reptiles
Reptiles Becoming Mammals: "There is no missing link [connecting] mammals and reptiles." - The Reptiles
"Fossils, unfortunately, reveal very little about the creatures which we consider the first true mammals." - The Mammals
Reptiles Becoming Birds: "The transition from reptiles to birds is more poorly documented." Processes of Organic Evolution
"No fossil of any such birdlike reptile has yet been found." The World Book Encyclopedia
Apes: "Unfortunately, the fossil record which would enable us to trace the emergence of the apes is still hopelessly incomplete." - The Primates
"Modern apes, for instance, seem to have sprung out of nowhere. They have no yesterday, no fossil record." - Science Digest
Ape to Man: "No fossil or other physical evidence directly connects man to ape." - Science Digest
"The human family does not consist of a solitary line of descent leading from an apelike form to our species." - The New Evolutionary Timetable
"The initial steps . . . are not known; . . . no trace of them remains." - Red Giants and White Dwarfs
