9.14 Data (for PBS)

We’ll calculate PBS using data from the paper: Tucci, S. et al. (2018). Evolutionary history and adaptation of a human pygmy population of Flores Island, Indonesia..

Flores Island was home to fossils of the archaic hominin species Homo floresiensis, also called “hobbits” because their skeletons are 3 ft. tall. It’s thought that H. floresiensis lived there until just 40k-30k years ago, overlapping with modern humans.

This study collected samples from individuals who currently live on Flores Island and scanned their genomes for evidence of natural selection. They calculated PBS between:

  • The Rampasasa (RPS) population from Flores
  • A Han Chinese (CHB) population
  • A Melanesian population from Papua New Guinea (PNG)
