Human Genetic Uniqueness Project
"we cannot fully understand human genome function until we have identified genetic features that underlie uniquely human anatomical, physiological, behavioral, and cognitive characteristics".
The Human Genetic Uniqueness Project allows Wikiversity students to join in the search for genes that account for the genetic differences between humans and our closest relatives. This project serves as a portal for learning about human biology. Student activities center on accessing genome databases and analysis of differences between human genes and the genes of other species. Background learning topics include learning about genes, and genome sequencing projects.

A starting point[edit | edit source]
Genes of the Chromosome 2 fusion site
Results from the chimpanzee genome support the hypothesis that when ancestral chromosomes 2A and 2B fused to produce human chromosome 2, no genes were lost from the fused ends of 2A and 2B. At the site of fusion, there is approximately 150,000 base pairs of additional sequence not found in chimpanzee chromosomes 2A and 2B. Additional linked copies of the PGML/FOXD/CBWD genes exist elsewhere in the human genome, particularly near the p end of chromosome 9. This suggests that a copy of these genes may have been added to the end of the ancestral 2A or 2B prior to the fusion event. Is there any evidence that the "newly" inserted genes of the chromosomes 2A and 2B fusion site might have confered a selective advantage on early human ancestors?
Learning materials and learning projects are located in the main Wikiversity namespace. Simply make a link to the name of the lesson (lessons are independent pages in the main namespace) and start writing!
You should also read about the Wikiversity:Learning model. Lessons should center on learning activities for Wikiversity participants. Learning materials and learning projects can be used by multiple projects. Cooperate with other departments that use the same learning resource.
