"How Incomplete Is The Fossil Record?<quoted text>Nothing besides the fossil record, genetics, comparative anatomy, biogeography, and 150 years of science work all supporting it.
But I guess that's not much compared to...a book that a primitive people wrote.
Darwin clearly thought the fossil record was very incomplete, and it probably is; the vast majority of species that must have lived on earth are not recorded in the fossil record. This isn’t really surprising. The chances of an organism becoming a fossil are slim, usually only hard materials are preserved, even then the dead organism has to avoid decay, scavengers, erosion by wind and rain, and must be covered in sediment and fossilised. Once a fossil has formed, over the millions of years following, the chance is very small that it will not be destroyed by; the immense pressure of the rock above it, the heat of the earth’s mantle below it, the heat and pressure as continental plates collide, or the processes of erosion which shape the earth’s surface! If a fossil does survive to the current day it has to be found and identified. Undoubtedly there are amazing fossils out there still undiscovered, certainly many new species of extinct species are described every year"
