DRAW IT (a) Draw a phylogenetic tree based on characters 1- 5 1n the table below. Place hatch marks on the tree to md1cate the origin(s) of characters 1-6. (b) Assume that tuna and dolphins are sister species, and redraw the phylogenetic tree accordingly. Use hatch marks to indicate the origin(s) of characters 1–6. (c) How· many evolutionary changes are required in each tree? Which tree is most parsimonious?

- The phylogenetic tree for 12 cat species (Felidae) reproduced at right was assembled from molecular sequence data. Which species is the domestic cats closest relative? Which clade is the sister taxon to tigers? Are bobcats more closely related to cougars or to ocelots? Source: From Warren E. Johnson et al. 2006. The late Miocene radiation of modern Felidae: A genetic assessment. Science 311:7377.arrow_forwardImagine that you have the DNA sequences fromthe intron of a gene in three species called A, B,and C. Species A and B are most closely related,while C is more distantly related. The sequencesof A and B differ by 18 base pairs, A and C differby 26 base pairs, and B and C differ by 28 basepairs. Fossils show that species A and B divergedabout 1.2 Mya, but there is no fossil evidence asto when the most recent common ancestor ofall three species lived. Use the genetic data toestimate that date. What assumptions are youmaking to get this estimate?arrow_forwardFigure out the order of evolution of each character. You have been given reason to believe that, based on the fossil record, Xenite A is the ancestral species. Create your cladogram for the Xenites. Identify which derived characters were homologies or analogies. Explain the evolutionary history of the organisms shown by your tree. How did you use evidence to create your cladogram?arrow_forward
- Along comes Dr Phil Bell and deep in the mines of Lightning Ridge, finds an amazingly preserved pterosaur that preserves feathers. He hypothesises that this means that feathers must have evolved before the origin of dinosaurs and therefore must have been primitive. Test this hypothesis using phylogenetic framework and provide a brief explanation of your process and whether or not you support Dr Bell's hypothesis.arrow_forwardMichael Bunce and his colleagues in England, Canada, and theUnited States extracted and sequenced mitochondrial DNA from fossilsof Haast’s eagle, a gigantic eagle that was driven to extinction 700 yearsago when humans first arrived in New Zealand (M. Bunce et al. 2005.PLOS Biology 3:44–46). Using mitochondrial DNA sequences fromliving eagle species and those from Haast’s-eagle fossils, they createdthe accompanying phylogenetic tree. On this phylogenetic tree, identify(a) all nodes; (b) one example of a branch; and (c) the outgroup.arrow_forwardBased on the results, what is the most probable phylogenetic tree(s) for these three beetles? A. the left phylogenetic tree because it has the fewest evolutionary events B. the middle and the right phylogenetic trees because they have the most evolutionary events C. the middle phylogenetic tree because the mutations caused Species I and III to develop similar coloring D. the right phylogenetic tree because the mutations caused Species II and III to develop a ridged body texturarrow_forward
- 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.arrow_forwardMake a list of at least 10 morphological characters that you might use to generate a phylogenetic tree of the Caminalcules. Ignore the numbers found next to each Caminalcules- they do not represent who evolved first, second, etc. 2.Construct a phylogenetic tree of relationships (Hint: it may be easiest to cut out the critters so you can move them easily and then paste on them on a paper and draw the branches accordingly). 3.Identify at least 2 recent common ancestors and write at least three critical morphological changes along the branches on which they occurred. For example, did the claws appear (or disappear) as the different species evolved? 4.Take a picture of your phylogenetic tree and submit it with this document. ***Please note, this lab can be frustrating because you are “creating” the evolutionary story of how these critters evolved and who is more closely related to who (or not) along the way. There is no wrong answer since every student will focus on different…arrow_forward7) Examine the image of the relatedness of vertebrates represented in this phylogenetic tree. Select all the statements that are supported by this tree. A) Gray whales are the common ancestor of the Blue and Humpback whales. B) Blue and humpback whales diverged more recently than either did from the gray whale. C) The Bryde's whale shares a more recent common ancestor with the Sei whale than with the Fin whale. D) The blue and the Bryde's whale have more traits in common with each other than with any other two species, E) Southern minke whales and Northern minke whales have more traits in common with each other than with any other species.

- Draw a phylogenetic tree based on characters 1-5 in the table below. Place hatch marks on the tree to indicate the origin of characters 1-6.

Figure out the order of evolution of each character. You have been given reason to believe that, based on the fossil record, Xenite A is the ancestral species. Create your cladogram for the Xenites. Identify which derived characters were homologies or analogies. Explain the evolutionary history of the organisms shown by your tree. How did you use evidence to create your cladogram?arrow_forwardWhen I first studied hominin evolution, they had found "Lucy", an Australopithecus afarensis, and everyone thought her species was an early ancestor of Homo sapien. The picture is much more complicated, with lots of hominins living in close proximity for millions of years...much different than our now singular species. Look at the phylogenetic tree and use it as a guide to briefly describe hominin lines in Africa up to Homo. Do not discuss Homo.Just discuss a sense that you generally can grasp what was going on in Africa with our Genus for 6 or 7 million years!arrow_forward
