Phylogenetic trees are constructed from evidence drawn from:
APhysical form alone
BMultiple disciplines
CA single experiment
DOne fossil only
Answer & Solution
Correct answer: B. Multiple disciplines
1. No one line of evidence settles a deep evolutionary relationship.
2. Scientists often construct phylogenetic trees based on evidence drawn from multiple disciplines.
3. Morphology, genetics and the fossil record all contribute.
4. Using several independent lines is what makes a tree trustworthy.
