Figure 26.12b Lancelet (outgroup) Lamprey Bass Vertebral column Frog Hinged jaws Turtle Four limbs Amnion Leopard Hair (b) Phylogenetic tree 2017 Pee tocaton, In the tree above, which is a derived trait between frogs and bass but is a shared ancestral trait among frogs and leopards? a) Hinged jaws b) Four limbs c) Amnion (egg) d) Hair e) All of the above

In the figure, what does the node indicated by the red dot represent? Lampreys Cartilaginous fishes Ray-finned fishas Lobe-finned fishes Amphibians Mammals Snakes Turtles Crocodilians Birds ) The most recent common ancestor of birds and crocodilians ) The last descendent of turtles The most recent common ancestor of all tetrapods O A population that would result from the hybridization of birds and crocodilians

Examine the image of the relatedness of vertebrates represented in this phylogenetic tree. Which statements are correctly inferred from this tree? Select all that apply.   A) The mammals are the outgroup in this tree.     B) Birds and dinosaurs share a recent common ancestor.     C) Mammals and birds are more closely related than any other species.     D) Turtles are equally as diverged from lizards and snakes as they are from crocodiles.     E) Lizards and snakes are more recently diverged from each other than they are from crocodiles.

How is the traditional animal family tree similar or different from the  phylogeny reflecting molecular data?

3. The table below lists four characteristics of the shrimp, silverfish, dragonfly, beetle, and butterfly. For each animal, (+) indicates that the character is present and (-) indicates the character is absent.

The tree below shows a proposed phylogeny of the three broadest mammal groups. monotremes marsupials eutherians Figure 1: Phylogenetic relationsbips between defrent ypes of mammals. a. Which group of mammals branched off the earliest? b. Which letter designates the common ancestor to monotremes and marsupials? c. Indicate where on the tree (short perpendicular line) each of the following characters arose. 1. long-lived placenta 4. internal gestation (rather than in egg) 2. body hair 5. long-term gestation 3. production of milk for young 6. live birth (rather than egg laying e. Which of the above characters are shared ancestral characters of eutherians? List all that apply.

Lobe finned fishes are considered to be an evolutionarily important group because;  (bubble both that apply) Group of answer choices 1) They have bones and musculature in their fins 2) They have a little bit of lung tissue 3) They lay an amniotic egg 4) They are tetrapods

4) What makes Archeopteryx an important fossil evolutionarily? A)This species has a mix of characters that suggest it was a "transitional" species between two large groups, dinosaurs and birds. B)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. C)This species has a mix of characters that suggests is was a "transitional" species between two large groups, fish and amphibians. D)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).

Which of the following is not correct?   A. The lung in the frog is homoplasious to the lung in the land snail   B. The arm bones of Barak Obama are homologous to those of Donald Trump   C. The hair of the tarantula is homoplasious to the hair on a platypus   D. Bilateral symmetry in the frog and the snapdragon flower is homoplasious   E. The dorsal fin of a shark and the dorsal fin of a dolphin are homologous.
