The fossil record is incomplete. Of the small proportion of organisms preserved as fossils, only a tiny fraction have been recovered and studied by paleontologists. In some cases the succession of forms over time has been reconstructed in detail. One example is the evolution of the horse.
Bones, shells, feathers, and leaves can all become fossils. Fossils can be very large or very small. Microfossils are only visible with a microscope. Bacteria and pollen are microfossils.
The fossil record, however, is quite incomplete. Here's one major reason why: Sediment has to cover an organism's remains in order for the long fossilization process to begin. Most organisms decompose before this can happen.
Because not all animals have bodies which fossilize easily, the fossil record is considered incomplete.
So, the correct answer is 'Limulus'
What is NOT true about the evidence that fossils provide? All fossils contain intact DNA that can be sequenced. Why don't we have a complete fossil record of all life that's ever lived? Fossil formation requires a rare mix of physical and biological conditions.
The fossil record is incomplete because most organisms never became fossils. And, many fossils have yet to be discovered. Scientists know more about organisms that had hard body parts rather than a soft body because hard body organisms favored fossilization.
fossil record. information about past life, including the structure of organisms, what they ate, what ate them, in what environment they lived, and the order in which they lived. extinct.
Since then, fossils have been considered among the most important evidence for biological evolution,” Hannisdal explains. However, in his book on the origin of species, Darwin argued that the fossil record was far too incomplete to give a reliable picture of evolution.
For many reasons, the fossil record is not complete. Most organisms decomposed or were eaten by scavengers after death. Many species lacked hard parts, which are much more likely to fossilize. Some rocks and the fossils they contained have eroded and disappeared.
Organisms that live where sediment is actively being deposited (e.g., beaches, swamps) are more likely to fossilize than are organisms in other habitats. Some organisms (e.g., those with hard parts such as bones or shells) are more likely to decay slowly and leave fossil evidence.
The results show that out of all the geological factors, only the area of preserved rock drives biodiversity. Therefore, the other geological factors -- counts of fossil collections and geological formations -- are not independent measures of bias in the fossil record.
