- 1. can be used for sexual, asexual, and fossilized organisms2. Many measurements are possible and quantitative
- 1. Widely applicable 2. Based on testable criteria (if DNA is obtained)
- How does random chance cause genetic change?
- 1. Group must be the subject of phylogenetic study (there must be data to analyze)2. Easy for study to OMIT rare, geographically isolated, or difficult-to-catch species
- 1. Clear criterion- reproductive isolation 2. Some degree of relatedness can be inferred 3. Highlights species' biology
- more numerous between different species because of their isolation from gene flow
- 1. NOT applicable to asexual or fossil species 2. Reproduction isolation is difficult to asses if there is no geographical overlap3. Not applicable to microbes because they reproduce by binary fission
