Exploring Phylogeny: Evolution of Species and Genetic Origins

Understand the evolution of species through phylogeny at the 1st EELA Conference in Santiago. Learn how genetic origins and shared ancestry determine relationships. Explore tree computation, sequencing, and MrBayes for the best phylogeny tree determination.

  1. Demo in WP3: Phylogeny Raúl Isea1, Fernando Blanco2, Rafael Mayo2 1CECALCULA 2CIEMAT 1st EELA Conference Santiago, 4-5.09.2006

  2. HYPOTHESIS Phylogeny is for the determination of the evolution of the species Two species share a genetic origin Santiago, 1st EELA Conference, 4-5.09.2006

  3. HYPOTHESIS Before Phylogeny After Phylogeny Santiago, 1st EELA Conference, 4-5.09.2006

  4. COMPUTING The number of trees depend on the number of sequences Trees without root Trees with root # sequences # no root # root Santiago, 1st EELA Conference, 4-5.09.2006

  5. COMPUTING Adding Sequences (taxons) Add taxons A and B With 3 seqs only 1 tree Add taxon C Add taxon D Add taxon E and so on Santiago, 1st EELA Conference, 4-5.09.2006

  6. EXAMPLE Human Evolution with 12 ADN sequences Santiago, 1st EELA Conference, 4-5.09.2006

  7. EXAMPLE MrBayes determines the best Phylogeny Tree 1000 phylogeny trees are generated in 10000 targets Santiago, 1st EELA Conference, 4-5.09.2006
