Why species Concepts are messy
- A barrier of reproduction emerges
Phylogenetic Species Concept (PSC)
• Single evolutionary series
Evolutionary Lineages and Trees
Natural Taxonomy → we group species together based off of evolutionary relationships
Evolutionary Species Concept
- Explicitly entails pathway that leads to species → But may not know their true species,
but just know they have a single evolutionary lineage
- How do we know if they are from a single lineage or not?
Teleopsis Pallifaces
- New species discovered in 1996, new species found all the time
- Just this year, two new species of monkeys were found
- A macaque was ID’ed

Document Summary
Lecture book and lab are fair game. Phylogenetic species concept (psc: single evolutionary series. Natural taxonomy we group species together based off of evolutionary relationships. Explicitly entails pathway that leads to species but may not know their true species, but just know they have a single evolutionary lineage. New species discovered in 1996, new species found all the time. Just this year, two new species of monkeys were found. New frog was found in new york on staten island cryptic species, looks exact like a leopard frog but has a distinct mating call. Yes, it is a species by all three criteria. It doesn"t have to be considered a species by only one criteria. Specimens in zoo wouldn"t breed because there were two different types, an older one and newer one. Giraffes different spots/evolutionary relationships considered a distinct species by. Not enough information is provided, we don"t know if their ranges overlap or are contiguous and can interbreed.
