Chapter 19.2, Problem 1TYK
Summary Introduction
Introduction:
Fossils are the dead remaining traces of the living organism. There are many processes of fossilization, but most of them are formed due to the embedding of the organism inside the rocks and under the ground.

- The Fossil Record is used to help explain the progress of evolution of species over the geologic time scale. Large gaps exist within the fossil record, however, because . Group of answer choices Fossilization is a very rare phenomenon, so not all species that existed are preserved in the fossil record Natural disasters, such as earthquakes, have destroyed many fossils that would have otherwise helped to fill in the gaps Scientists have failed to find all the fossils that are trapped within the Earth's crust There is only one Indiana Jones, and he can't possibly find all the artifacts "that belong in a museum!"arrow_forwardWhich of the following statements about ancestral and derived traits are true? Ancestral traits are shared by taxa due to common ancestry (e.g., the ancestor had that trait). Derived traits are present in all members of a phylogeny Derived traits are new characteristics that evolved in a lineage after divergence from a common ancestor with an ancestral trait. Ancestral traits are unique to a single species.arrow_forwardWhich of the following is evidence that supports Darwin's theory of common descent? (Choose all that apply) There are patterns in the fossil record that suggest some species have diverged from a single ancestral species There are biogeographic patterns in the distribution of species, for instance, distinct bird species on an island tend to resemble one another, s ancestor There are common stages in the early embryological development of organisms in several distinct vertebrate groups. Anatomical structures, such as forelimbs, in different groups appear to be modified versions of structures that might have been present in a co Similar anatomical features in different organisms always indicated close common ancestryarrow_forward
- Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects? All these organisms require oxygen to survive. The earliest fish fossils are found in the lowest strata of sedimentary rocks, followed by insects, and then humans. The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans. Fossils of ancient fish and human ancestors have been discovered in the same sedimentary rock layers.arrow_forwardWhich of the following does NOT provide evidence for the theory of evolution? the existence of homologous and vestigial structures structural and chemical homologies recorded observations of an individual organism in a population fossils presence of DNA in all organismsarrow_forwardBoth humans and chimpanzees have large brains and well developed eyes.
