Based upon the figure above, the phylogenetic tree 1. depicts uncertainty about the evolution within the Stramenopiles, as well as the relationships between the Excavata, SAR clade, Archaeoplastida, and the Unikonta. 2. depicts an evolutionary hypothesis 3. includes polytomies 4. indicates that the Excavata are more closely related to Archaeplastida than any other clade A) 1, 3, and 4 B) 1, 2, and 3 C) 1 and 3 D) 1 and 2 22.) W hich of the following is not true of all horizontally oriented phylogenetic trees, where time advances to the right? A) Each branch point represents a point in absolute time. B) The more branch points there are, the more taxa are likely represented. C) The more branch points that occur between two taxa, the more divergent their DNA sequences are likely to be. D) The common ancestor represented by the rightmost branch point existed more recently than the common ancestors represented at branch points located to the left.Explanation / Answer
Ans 19 )
The salamender lineage is a basal texon.
Ans 20) b three
A monophyletic group can be separated from the root with a single cut, whereas a non-monophyletic group needs two or more cuts.
Ans 21)a. 1,3,4
Ans 22) d. The common ancestor represented by the rightmost branch point existed more recently in time than the common ancestors represented at branch points located to the left.
