How do shared derived characters help cladistic taxonomists determine phylogenetic relationships?
34
A paleontologist studying two modern species finds a 7-million-year-old fossil organism with a morphology similar to the modern species and concludes that it is an ancestor of both. A molecular biologist studying the amino acid sequence of a particular protein in both modern species concludes that the two species last shared a common ancestor 12.5 million years ago. Suggest possible reasons for the discrepancy in the two conclusions.
