Which of the following is true: Clades are groupings that reflect levels of adaptation or overall similarity and not necessarily actual evolutionary relationships. A grade is a grouping of organisms that reflect a branch of the evolutionary tree, Prosimii and Anthropoidea are an alternative grade-based classification Genetic evidence suggests that Tarsiers are more closely related to Lemurs and Lorises than they are to haplorhines None of the above

Which of the following is a correct statement about the evolutionary relationships among vertebrates? Group of answer choices Mammals are more closely related to amphibians than amphibians are to snakes Mammals and snakes are more closely related to each other than either are to amphibians Crocodiles are more closely related to lizards than they are to birds Birds are more closely related to mammals than they are to crocodiles
Consider the following traits: Opposable thumbs, forward-facing eyes, nails, tactile fingerpads, large brain, and protective bony eye orbits. All of these are examples of: Group of answer choices Ancestral traits of primates shared with the mammalian common ancestor. Traits lost by primates that were present the mammalian common ancestor. Derived traits of primates not present in the mammalian common ancestor. Derived traits of primates shared with the mammalian common ancestor.
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.
Which of the following does not represent a shared derived homologous trait, in other words, which IS an example of an analogous trait? Group of answer choices bony vertebrae of rabbits and monkeys five digits on the end of the limbs of a whale and human wings of both a bird and insect forward facing eyes in chimpanzees and humans
Which of the following data sets is the one that scientists had to evaluate carefully since it made the artiodactyl phylogenetic tree less parsimonious? DNA sequence similarity between hippos and whales was the highest compared to other artiodactyls fossil evidence of animals that had traits of both whales and land mammals anatomical comparison between whales, other mammals, and fish presence of an astragalus bone in artiodactyls but not whales
Using the terms listed below, answer all the parts to this question regarding the cladogram for the frogs Anatomy of a Cladogram Sympleisiomorphies—shared ancestral states Synapomorphies—shared, derived character states Autapomorphies—unique, derived character states Homoplasies—the result of parallel or convergent evolution where 2 or more organisms independently acquire the same character state (could be the result of a reversal—when, in a particular lineage, a character reverts from a derived back to an ancestral state). Similarity in appearance, but not origin. Monophyletic group—group of all descendants of a common ancestor Paraphyletic group—group of some, but not all, descendants of a common ancestor Polyphyletic group – group of individuals that descend from more than one common ancestor Polytomy—3 or more taxa emerging from a single node who do not share the most common ancestor Homologies—Similarities resulting from descent from a common ancestor Analogies - Similarities…

The presence of tiny hairs, called setae, on the toe pads of some geckos is associated with the ability to adhere to smooth surfaces. This ability allows geckos to climb in areas where many predators cannot. Scientists studying the evolution of setae have identified three closely related species of gecko, only one of which can adhere to smooth surfaces. A model of the evolutionary relatedness between these species is represented in the figure. Which of the following statements is an accurate interpretation of the labeled branch points on the model?
According to the traditional classification of vertebrates, class Reptilia is a paraphyletic group because it does not include all descendants of a common ancestor. Which group has been left out of the classification but is really part of the reptile clade? Group of answer choices Birds Fish Amphibians Mammals
When comparing traits between two organisms in order to determine evolutionary relationships, the wings of birds and the wings of butterflies is an example of which of the following? Group of answer choices analogous traits traits useful in constructing cladograms shared derived traits homologous traits
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.
