In a phylogenetic analysis of several bird species, a researcher uses a species of reptile as an outgroup. Which of the following is the main reason for including an outgroup in the analysis? To identify ancestral traits shared by the bird species To determine the overall genetic diversity of the bird species To establish a new monophyletic group including both bird and reptile species To analyze the convergent evolution of bird and reptile species

Recent reconstructions of evolutionary history are often dependenton assigning divergence in terms of changes in amino acid ornucleotide sequences. For example, a comparison of cytochromec shows 10 amino acid differences between humans and dogs,24 differences between humans and moths, and 38 differencesbetween humans and yeast. Such data provide no information asto the absolute times of divergence for humans, dogs, moths, andyeast. How might one calibrate the molecular clock to an absolutetime clock? What problems might one encounter in such acalibration?

How, specifically, is the concept of ALLOMETRY relevant to the phylogenetic position of Homo floresiensis? Because if allometry explains the anatomy of Homo floresiensis then we can conclude that it is not separate species but instead a member of our species. Although most mammals on islands go through a process of getting smaller, Homo floresiensis evolved from a smaller ancestor to be bigger, meaning that allometry is an important factor. Mutations in the allometry allele are associated with many of the characteristics of Homo floresiensis. Because Homo floresiensis is so much smaller than other members of the genus Homo, it is important to determine how shape changes associated with smaller size impacted the species. Because Homo floresiensis had both small- and large-bodied forms, variation within the species is in large part dictated by allometry.
On the right is a phylogeny depicting the relationship among eight animal species (A to H). Next to the species names are the tooth morphology of each species. For example, species A has prominent molar teeth, thus likely a herbivore. On the other hand, species C has prominent canine tooth, thus likely a carnivore. Which of the following statements is correct? O The most recent common ancestor for species A to H is probably a carnivore: O The most recent common ancestor for species A to H is probably a herbivore OIt is impossible to tell what the main food source is for the most recent common ancestor of species A to H. O For species C, D, E, F, G, there are four evolutionary events that lead to the evolution of canine tooth morphology If the common ancestor of species C, D, E, F, G is a carnivore, then the molar teeth for species D is a plesiomorphy.

Which of the following conclusions is most consistent with the information in the evolutionary tree shown below? Each branch point represents the common ancestor of the two lineages diverging from that point. Lungfishes Amphibians Mammals Digit-bearing limbs Lizards and snakes Amnion Crocodiles A hatch mark represents a homologous characteristic shared by all the groups to the right of the mark. Ostriches Feathers Hawks and other birds O Mammals are more closely related to birds than to amphibians. O Lizards and crocodiles (both of which have legs) are more closely related to each other than either is to snakes (which lack legs). O Crocodiles are more closely related to hawks than to lizards. O Modern lungfishes are the common ancestor of modern tetrapods. Tetrapods Amniotes Reptiles Birds
A phylogeny of 5 species of birds is shown below with values for three different phenotypic traits for each species shown in the rows above (e.g., species A has a wide, long beak and red tail, while species C has a narrow, very long beak and a green tail). DNA sequencing of tissue samples found buried in a freezer confirms that an extremely rare and reclusive species (D) is a sister species of E, but preserved samples of entire individuals of species D have been lost, the original collector of the samples has passed away, and no individuals of species D have subsequently been seen in the wild. In other words, we have no idea what species D looks like. Employing the principle of parsimony, which of the following conclusions is MOST appropriate for the likely values of these traits in species D? Beak width: wide wide ?? narrow narrow Beak length: long long ?? long very long Tail colour: red blue ?? green green A E a) wide beak, very long beak, green tail b) narrow beak, long beak, all…

What is the function of including an outgroup in this phylogeny? After all, the point of the phylogeny is to see which Galapagos finch species are most closely related to each other.
A 2015 article in Nature has summarized the early history of jawed vertebrates using highlights from recent discoveries and how they have changed our understanding of vertebrate evolution. https://www.sciencedaily.com/releases/2014/04/140416133336.htm Question: Given these recent discoveries, how should the cladogram below change? Describe it. It will likely be helpful to reference a synapomorphy noted on the cladogram.
Which of the following is true regarding the way we define clades with characters? Select one: a. Autapomorphies are good characters to use because they describe every lineage of the clade and no other lineages b. Plesiomorphies are good characters to use because they describe every lineage of the clade and no other lineages c. Synapomorphies are good characters to use because they describe every lineage of the clade and no other lineages Please give me the correct answer quickly I will give you upvote
