  1. Human Genetic Diversity By NataliyaProkhnevska Stanley David Alexander Reese Ryan Haddock JuneHee Chang

  2. Introduction • Phylogenetic trees are a way of organizing data that show evolutionary patterns and relationships www.bio.umass.edu

  3. Introduction • Scientists use machines called sequencers to sequence entire genomes from collected tissue samples. They use this data to study human genetics and make phylogenetic trees. • A project called 1000 genomes was started by researchers to establish a phylogenetic tree of the entire human race. African-American populations were understudied, so researchers decided to look into their genome.

  4. Data • This is the allele frequencies that were collected from the sequenced genomes of each of the different populations of hunter-gatherers Lachanceet al. 2012 www.sciencedirect.com

  5. Results www.sciencedirect.com

  6. Discussion • By finding the differences in the sequenced genomes they were able to produce a phylogenetic tree where the different populations of African hunter-gatherers fit into. Lachanceet al. 2012 www.sciencedirect.com

  7. Conclusion • Phylogenetic trees use genetics in order to map out how populations change over time and how they are related to each other.
