Human Genetic Diversity By Nataliya Prokhnevska Stanley David Alexander Reese Ryan Haddock JuneHee Chang

Introduction  Phylogenetic trees are a way of organizing data that show evolutionary patterns and relationships

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.

Data  This is the allele frequencies that were collected from the sequenced genomes of each of the different populations of hunter-gatherers Lachance et al. 2012

Results

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. Lachance et al. 2012

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