Which of the following is not a known bias in the fossil record? Fossils from well-studied areas are more likely to appear in the fossil record More abundant species are more likely to be found and in the fossil record Mammals preserve better than birds. Shells and skeletons preserve better than soft-bodied animals.

Which of the following is the most likely organism to fossilize and be found in the fossil record? The earliest forms of bacteria A jellyfish with a soft body An octopus with a soft body A crustacean with a hard exoskeleton
Which statement is true? Fossils can provide information about when life forms existed. Fossils cannot provide information about life cycles and behaviors. Fossils cannot provide information about relatedness of life forms. Fossils can provide information about the entire evolutionary process of life forms.
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!"
Which one of the following statements is not true? Speciation is the process of creating new species There have been five mass extinctions preserved in the fossil record All living things can be classified into one of four taxonomic domains Some bacteria are autotrophs Current rates of extinction are higher than background extinction rates
You are examining the fossil record and notice a dramatic decrease in species diversity that seems to span across multiple groups of organisms within a very short period of time. This could most likely indicate: The beginning of a new geologic period A mass extinction event A major evolutionary breakthrough An artifact of poor fossil preservation adaptive radiation
Which of the following statements is incorrect in the context of fossilization? Minerals dissolved in the water gradually replace minerals in bones Sediments that slowly accumulate on top of the site extert increasing pressure Extreme pressure transforms the mineralized remains into rock. Impressions form detailed imprints of only external structures. Mineral particles settle out of the groundwater and crystallize inside cavities.
The number and location of bones within fossilized vertebrate skeletons are similar to those in living vertebrates. Most biologists explain this fact by saying that extinct and modern vertebrates had similar needs had different genes both struggled for existence both share a common ancestor 1 3 4 Next
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.
Which organism is most likely to fossilize? A tropical frog A forest dwelling lizard All animals have the same probability of leaving fossil behind A marine snail A jellyfish
Which of the following can be used to uniquely identify killer whale indivdiuals? saddle patch pigmentation patterns all of the options are correct notches in dorsal fin variation in dorsal fin shape oval scars Which of the mass extinctions in the past (before humans dominated the earth) was the most severe? Permian Triassic Devonian Cretaceous none of the options are correct
Transitional species are species important in helping scientists determine the evolutionary path that species have taken over long periods of time. Lobe-finned fishes are the ancestors of amphibians and have fossils that are found in rocks that are at least 380 million years old. Fossils of the oldest amphibian-like vertebrate animals with true legs and lungs are found in rocks that are approximately 363 million years old. Paleontologists have found a sample of rock that is approximately 370 million years old which contains what seems to be a link between lobe-finned fishes and amphibians. Which of the following is a characteristic that you would not expect to see in this transitional fossil? Question options: Skeletal structures that indicate the development of legs. An intermediate structure between lungs and gills. Teeth that are intermediate to the lobe-finned fishes and amphibians. A neck that is more flexible than lobe-finned fishes.
Which statement is true? Recent remains of plants or animals on topsoil are fossils. Imprints of leaves or footprints in sedimentary rock are fossils. Insects preserved in hardened tree sap are not fossils. Petrified skeletal bones from an ancient mammal are not fossils
