Solved in 2 steps
- Some organisms that appear very closely related on a phylogenetic tree may not actually be closely related. Why is this?Do you find it easy to interpret phylogenetic trees? What aspects are the most challenging or what aspects of the tree can be easily misinterpreted? What strategies can students use to correct or avoid these common misinterpretations? Do you consider phylogenetic trees to be reliable indicators of evolutionary relationships? Include a reference.Define parsimony. How is it used to build phylogenetic trees?
- When constructing phylogenetic trees, what is the purpose of applying maximum parsimony? Parsimony allows the researcher to "root" the tree. For trees based on morphology, the most parsimonious tree requires the maximum evolutionary events. The outgroup roots the tree, allowing the principle of parsimony to be applied. For trees based on morphology, the most parsimonious is the one that uses the simplest explanation of evolutionary events.Why is it so important for scientists to distinguish between homologous and analogous characteristics before building phylogenetic trees?Which statement is usually true about phylogenetic trees? a) nodes represent points when traits have evolved b) branch tips that are next to each other are more closely related c) the branching pattern describes the hypothesized evolutionary relationships between the taxa d) the order of the branch tips (left to right) indicates which taxa are more advanced evolutionarily
- Why are paraphyletic groups considered as bad groups in a phylogenetic tree?Examine the following phylogenetic tree illustrated in Figure shown in the first picture. In general, what does a phylogenetic tree illustrate? How do you compare the relationships of organisms BB, CC, and DD? Given the following organisms in the Table in the second picture, number them in terms of which is relatively closest and distant. Number 1 refers to closest.What is the difference between a cladogram and a phylogenetic tree? Given a cladogram for a group of species, what additional interpretation is needed to obtain a phylogenetic tree?
