Pre-History

__** Chromosome 13: Pre-History **__ Ridley uses Chromosome 13 to show the migration of humans across the globe. He explores the idea that genetic diversity is ever present in our society. Despite our political ideologies, religious differences, and economic status, we are united by the idea that we are all people made of genes that express our true identities. Chromosome 13 embodies the idea of evolution and how our national origins come into play.



//** "These two processes - linguistic philology and genetic phylogeny - are converging upon a common theme: the history of human migration" (Ridley 185). **//

__** Pautau Syndrome **__ Patau's syndrome is a chromosomal abnormality. Babies are normally born with 46 chromosomes. These are arranged in 23 pairs. Children with Patau's syndrome have an extra copy of chromosome 13 in every cell of their body. Patau's syndrome is also called Trisomy 13. It is the most severe of all chromosomal abnormalities.

// "Genes, in other words, support the evidence for linguistics that expansions and migrations of people have played a great part in human evolution" (Ridley 189). //
