The color on the tail fins of species B and C is best described as the result of evolutionary reversal. O b. The dorsal fin coloration seen in species A and C is likely due to convergent evolution. Oc. The presences of spots on species A and C is best explained by homology. Od. The color of the pectoral and pelvic fins in species A, B, and D is best explained by homoplasy.

Megan, a paleontologist, is working with a new fossil collection of trilobites from the paleozoic era. Part of her research is figuring out how many species of trilobites are in this new collection. What species concept will Megan not be able to use while doing her work?

Which of the following is true regarding vestigial traits? A) They represent transitional character states for example between the presence or absence of a feature. B) They help to support proposed phylogenetic placement. C) They are likely present because there is no fitness cost to their retention or because they are in the process of being removed due to light selective pressure. D) All of the above. E) None of the above.
10. Refer to the figure shown. Species Stripe Color 1 2 3 B. C R The figure shows the phylogeny of seven species of beetles (A-G) and whether the beetles have (?) or do not have (x×) one of three stripes. It also indicates the color of the beetle (R for red and G for green). Based on the phylogenetic tree and the principle of parsimony, the absence of stripe in species is most likely O 1; E and F; an evolutionary reversal O 2; E and F; due to convergent evolution O 2; E and F; a synapomorphy O 1; E and F; a synapomorphy O 1; E andF; due to convergent evolution
Part I: Construct a phylogeny Below is a list of seven hypothetical, currently-living species (A-G), and eleven of their character states (i.e., traits). You will use these traits to construct your tree.

To test evolutionary hypotheses, you make a phylogeny of a group of organisms based on six traits. You suspect tree dwelling evolved to allow for nest building A В 4 C 1 2 E F 5 3 2 1= singing 2= nest-building 3= short legs J K 4 4 = hollow snout M 5= crest 9- N 6=tree dwelling a) Based on your phylogeny, did tree dwelling evolve to allow nest building? Explain your answer. b) Your friend wants to put all of the species that have short legs into a single taxonomic group. Is this a good taxonomic group? Explain your answer. CO
Choose True for yes and False for no, for each of the statements 1) If fossil evidence of the most recent common ancestor of A and B (10 million years ago) was found on both sides of the river (that formed 20 million years ago), then the distribution of A and B is best explained by vicariance. True or false 2) Is It possible that species C will speciate ? True or false
3. Module 1. Ecomarobs a. Observe the morphologies of the eight different lizard species. For now, assume that you have just discovered these lizards and you don't even know if they are 8 different species or 1 species or some other number of species. You just have 8 lizards, 4 from each island. b. Following the module, group the lizards by morphology. i. How many groups did you find?_ ii. What sorts of traits or characters did you use to group the lizards? c. Then take some more careful measurements as shown and regroup them if needed. i. Did your measurements match the reference set? ii. Compare Lamellae Count, Relative Hindlimb Length, and Relative Tail Length among your specimens, and regroup your species based on these characters. iii. Did your groupings change? If so, how? iv. Watch the video to see if your conclusions match those of Dr. Losos d. Now. If this is all you knew about these lizards, how many "species" would you conclude there are? e. What sort of species definition…
