Two versions available, for grades 5-8 and 9-12; adapatable to grades K-4.Fossils Key to Both Views . Strangely enough, scientists in both camps cite the fossil record as evidence to support their views. Proponents of punctuated equilibrium point out that there are many missing links in the fossil record. If gradualism is the correct model for the rate of evolution, they argue, there should be fossil records that show …Hippos likely evolved from a group of anthracotheres about 15 million years ago, the first whales evolved over 50 million years ago, and the ancestors of both these groups were terrestrial. These first whales, such as Pakicetus, were typical land animals. They had long skulls and large teeth that could be used for eating meat. First Published:  22 February 2010. Abstract. PDF.

Fossils can also be used to date rocks. Through the process of evolution, different kinds of fossils occur in rocks of different ages, enabling geologists to use fossils ...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 ...But while fossils are trapped in ancient rocks, the fossil record is far from written in stone.

However, interpretations of fossil record diversity patterns have been much debated, with a traditional focus on global diversity through time. ...Some of these features, such as grazing dentition, appear abruptly in the fossil record, rather than as the culmination of numerous gradual changes. Eohippus , moreover, gave rise to many now-extinct branches of the horse family, some of which differed substantially from the line leading to the modern equines. 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 stochastic nature of the fossil record means that the gap size between FADs and true divergence times will be heterogeneous in size, which becomes relevant ...Introduction. The fossil record of chondrichthyans from the Florida Platform has been a major gap in paleodiversity studies.
