1. A modern goal of systematics is to create taxa based on similarity of form and function, regardless of evolutionary relationships.
2. An assumption used for molecular clocks is that neutral mutations accumulate at a rapidly increasing rate over time between two species.
3. Alan Cooper, Cécile Mourer Chauviré, Geoffrey Chambers, Arndt von Haeseler, Allan Wilson and Svante Pääbo investigated the evolutionary relationship among some extinct and living species of flightless birds. They used tissue samples from museums and from living birds. This is an example of discovery-based science.
