Question

Any aspect of an organism's phenotype may be used to reconstruct a phylogenetic tree.

True

False

In cladistics, any form of similarity or dissimilarity is suitable for determining evolutionary relationships.

True

False

Cladistics is not always the most effective method of reconstructing evolutionary relationships.

True

False

When different characters evolve at different rates, cladistics is the most effective method of reconstructing evolutionary relationships.

True

False

Statistical methods of reconstructing evolutionary relationships are generally more effective to use than cladistics when the overall evolutionary rate is very high.

True

False

A timeframe cannot be assigned to branching events in an evolutionary tree.

True

False

A molecular clock can be used to find the relative timing of events in a phylogenetic tree, and fossil references can be used to find the timing of evolutionary events also.

True

False

Explanation / Answer

Q1. True. A phylogenetic tree can be constructed based on similarities and differences in their physical or genetic characteristics.

Q2. True. In cladistics, classification is done based on shared derived characteristics that can be traced to a group's most recent common ancestor and are not present in more distant ancestors.

Q3. True. Cladistics is not always effective as there are other factors such as homology, synapomorphies etc are not being accounted for.

Q4. False.

Q5. True.

Q6. True

Q7. True
