The images below exhibit Y-5 molars. The left comes from a chimpanzee and the other is a zoomed-in image of Y-5 molars in a human. Why do these primates share the trait for Y-5 molars? Mark the best answer. Group of answer choices Unclear, cannot determine from the information given. Both inherited this trait from their common ancestor, which also had Y-5 molars. Convergent evolution, since both separately evolved Y-5 molars to adapt to dietary pressures. Random mutations, since having Y-5 molars is abnormal in these species of primate.
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
Which of the following characteristics are indicative of primates only? homodont teeth post-orbital bar/closure heterodont teeth
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 best describes the evolution of smell in chordates? A) Ancestrally, jawless fish had few ancestral scent genes that coded for receptors resembling a combination of water and air receptors. Subsequently these genes were duplicated and specialized through natural selection either for use in water or air. B) Ancestrally, all olfactory receptors where specialized for water as the ancestor of all vertebrates was aquatic. Only once did olfactory genes become duplicated and specialized and this was in the transition to land for receptors that work in air. C) All chordates share the same number of scent receptor genes. However, they have become variously deactivated through natural selection due to either unuse or a tradeoff for sight genes. D) None of the above.
What makes Archeopteryx an important fossil evolutionarily? This species has a mix of characters that suggest it was a "transitional" species between two large groups, dinosaurs and birds. This species is the oldest known, universally agreed upon, fossil of life, and therefore tells up what the common ancestor to all living things might have been like. This species is thought to be the last common ancestor between chimps and humans, and therefore is the root of our own specific group (homonins). This species has a mix of characters that suggests is was a "transitional" species between two large groups, fish and amphibians.
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
From this lab, one might conclude that certain trends can be detected, trends from ancestral features (those that arose early in the evolution of animals) to more derived traits (those that arose later). However, animals with ancestral characteristics still successfully exist on Earth today. Why is this so? Why have the animals with derived traits not completely replaced the ones with ancestral traits? Use examples from the lab to illustrate your answer. examples cephalochordata jawless fishes jawed fishes tetrapods rat
Human embryos have tails which become tail bones before birth. Tails also appear in fish, reptiles, amphibians, birds, and mammals Humans also have hair and produce milk to nourish the young, which is unique to mammals. What does this indicate? a close evolutionary connection between humans and many other mammals a very distant evolutionary connection between humans and many other mammals a very distant evolutionary connection between humans and many other reptiles a close evolutionary connection between humans and many other reptiles
Which of the following is NOT true about the Homo floresiensis fossil remains? Group of answer choices Were likely afflicted with a severe growth defects May have evolved from ancestors that left Africa before Homo erectus They were recovered in Liang Bua Cave on the island of Flores, east of Java have been affectionately named "the Hobbits" Were contemporary with modern humans 25 kya
A bird, from a modern phylogenetic systematic perspective, is properly classified as a member of all of the following except Group of answer choices Archosaur Gnathostome Amniote Synapsid
The two primates shown below both exhibit large eye orbits. One is a tarsier, the other is an owl monkey (the only nocturnal platyrrhine). Why do these primates share the trait for large eyes? Mark the best answer. Group of answer choices Random mutations, since having large eyes is abnormal in these species of primate. Convergent evolution, since both separately evolved large eyes to adapt to a nocturnal activity pattern. Both inherited this trait from their common ancestor, which was also nocturnal with large eyes. Unclear, cannot determine from the information given.
