What is a transitional fossil? Transitional fossils were poorly adapted to their environments. O Transitional fossils have features that are intermediate between ancestors and descendants. Transitional fossils only existed for a short period of time. A transitional fossil is in the middle of a direct lineage stretching from ancient forms to organisms alive today

Even though paleontologists and anthropologists are continually finding new fossils, there is still a lack of fossils overall. Explain.
by studying the limbs and fossils of different animals, such as a horse leg and a human leg, scientists have noticed that there are similarities in their bone structures. this is evidence that their bone structures and limbs may have evolved in similar ways. The scenario is describing a relationship known as causation . The scenario is describing intermediate fossils . The scenario is describing a relationship known as correlation . The scenario is describing transitional fossils .
Fossil A is found closer to the surface compared to Fossil B. Which of the following conclusions can be made based on this statement ? Fossil B is most likely older than Fossil A The species of Fossil A evolved from the species of Fossil B. Fossil A is from an older species than Fossil B. The species of Fossil A existed at the same time as the species of Fossil B.
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 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
What are the two ways of finding the age of a fossil? Describe how relative dating works. What does absolute dating do? Why is the element carbon-14 important for paleontologists? . Developmental Biology - Embryology Many scientists use what an organism looks like as an embryo, or embryology, as evidence for evolution. The embryos of most vertebrates look very similar and have similar structures. For example, fish, bird, rabbit, and human embryos are similar in appearance in early stages. They all have gill slits and a tail with muscles to move it. Later as the embryos develop, they become less and less similar. What does the study of embryology show when comparing most vertebrates?
Many of the morphological differences (e.g. bigger brains, shorter limbs, greater robustness) observed in Neandertals compared with other hominin fossils have been explained as being a result of... Group of answer choices speciation lack of technological advances adaptations to high altitudes adaptations to cold environments island dwarfism
Why are simpler structures considered ancestral when we study phylogeny? * 1 point Complex structures often evolve from simpler ones. Time element is a major consideration. The presence of a character state among some members of a lineage and an outgroup indicates that the character is ancestral. Simpler structures were more likely to be found in fossil records.
Derived characters are traits that characterize the last common ancestor that a particular collection of species share. evolved after the last common ancestor that a particular collection of species share. are less suited to the environment than ancestral characters. are more complicated than ancestral characters.
