Fossil record.

The fossil record cannot accurately determine when one species becomes another species. However, two hypotheses regarding speciation also exist. Phyletic speciation suggests that abrupt mutations in a few regulatory genes occur after a species has existed for a long period of time. This mutation results in the entire species shifting to … The Fossil Record The claim that fossils document evolution is simply not true. ICR geologist Dr. John Morris and zoologist Frank Sherwin unearth the evidence of earth’s history and conclude that the fossil record is incompatible with evolution, but remarkably consistent with the biblical account of creation and the great Flood of Noah’s day. paleontology, scientific study of life of the geologic past that involves the analysis of plant and animal fossils, including those of microscopic size, preserved in rocks.

Fossils are the remains of once-living things. They can be plant or animal bodies that have been partially or completely replaced by minerals. They can be impressions that just show the shape of a creature, or tracks left behind by a traveler, or other remnants that testify to the lives of long-gone organisms.

Fossil Record Examples The fossil record is filled with example organisms from Earth's past. The fossil record helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era.
