The phylogenetic tree to the right showsthe evolutionary relationships of taxa A –H. The shapes represent character statetrait changes. A. Which traits (shapes) would individualsin taxa D have? Draw the collection oftraits. B. Is the triangle a synapomorphy orpleisomorphy (circle one)? C. Is the circle a synapomorphy orsympleisomorphy (circle one)?
In cladistic analysis, (a) ancestral characters are used to reconstructphylogenies (b) characters must be homoplastic (c) polyphyletic groups are preferred (d) outgroup analysis is rarely used (e) shared derived characters are the preferred evidence for relatedness
A- species A and B are considered sister taxa B- A trait unique to species G is best described as a plesiomoephy among all taxa C- A trait unique to species K and L is best described as an apomorphy among all taxa D- A trait in common between species E, F, and G would make them a monophyletic group
In a paraphyletic group a. all species are more closely related to each other than they are to a species outside the group. b. evolutionary reversal is common. c. polyphyly also usually occurs. d. some species are more closely related to species outside the group than they are to some species within the group.
Paraphyletic groups... A. represent the most recent common ancestor and all of the descendants B. Are a potential consequence of secondary loss of a trait C. Are often created when attempting to build phylogenies for species that have undergone convergent evolution D. Are more likely when making trees using the biological species concept
Which is a criticism of sympatric speciation? A.) many cases of sympatric speciation are actually microallopatry B.) allopatric speciation is less common and scientists should focus more attention on locating additional examples C.) sympatric speciation is only associated with changes in ploidy, a process so rare that it's relatively unimportant D.) since most examples of sympatric speciation involve post zygotic isolation, hybridization nearly always results in their reversal
The group designated as A+B (which includes the immediate internal node of each descendant) represents the smallest monophyletic grouping in this radiating cladogram. But a group designated as E+F+G - A. would be paraphyletic. B. would be polyphyletic. C. would also be monophyletic. D. cannot be determined.
Which of the following factors would not contribute toallopatric speciation?(A) The separated population is small, and genetic drift occurs.(B) The isolated population is exposed to different selectionpressures than the ancestral population.(C) Different mutations begin to distinguish the gene pools ofthe separated populations.(D) Gene flow between the two populations is extensive.
Two different monophyletic groups that share common ancestry with each other more recently than either does with other taxa are known as?
In a phylogenetic tree, Species 1 and 2 are distantly related to one another but are both darkly pigmented. Species 3 which is unpigmented is a sister taxon to Species 2. The common ancestor to all three species is darkly pigmented; thus, this trait in the phylogeny is considered to be a - A. homoplasy. B. synapomorphy. C. apomorphy. D. symplesiomorphy.
In interpreting a cladogram, (a) we can identify the specific ancestor of each taxon by tracing each branch back to the node closest to the root (b) taxa on the right side of a cladogram have evolved from the taxa on the left side (c) the relative placement of smaller branches allows us to determine the number of years since a particular taxon has evolved (d) we can determine relationships by tracing along the branches back to the most recent commonancestor (e) we must first identify horizontal gene transfer
