What is the fossil record?

Amniotes evolved ~340 million years ago, but the oldest known fossilized amniote eggs are from the Late Triassic, over 200 million years later. Preservation probably played a large role in the hiatus between evolution and preservation, as some kinds of eggshell are more easily fossilized than others.

The fossil record of the past 6 million years reveals the transition from chimp-like species with smaller average brain sizes to species that are increasingly human-like in appearance (i.e., bipedal), with larger average brain sizes (see also the speciation section of this chapter).

The use of temporal information from the fossil record as data in phylogenetic inference has been criticised however, with concerns ranging from the incompleteness of the geological record to the non-clocklike evolution of morphology .

Jun 12, 2020 · The fossil record of early eukaryotes traditionally has been dismissed as useless for reconstructing eukaryogenesis, in part because the important transitions involve characters which are typically not preserved (e.g. the nucleus, mitochondria, cytoskeleton), and in part because the prevailing view of early eukaryote evolution assumes these ...

There is little fossil evidence for the divergence of the gorilla, chimpanzee and hominin lineages. 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. Unfortunately, most early life forms are too small to be preserved in the fossil record.
