What is a potential problem with the parsimony approach to reconstructing evolutionary history?
What is a potential problem with the parsimony approach to reconstructing evolutionary history?
- It assumes the most complex explanation is the correct explanation.
- Evolutionary reversals may make a trait appear and disappear again (correct)
- DNA data might conflict with the fossil data
- It assumes that evolution occurs gradually but perceptively
