Phylogeny

• phylogeny= evolutionary relationships between organism.

  • Shows which group organisms are related to and how closely they are related.
• Phylogenetic tree= diagram used to represent the evolutionary relationships between organisms.

  • They are branched diagrams which show that different species have evolved from a common ancestors.
• Advantages of phylogeny

  • Produces a continuous tree, not forced to put organisms into specific groups.
  • Not misleading as it doesn't imply that different groups within the same rank are equivalent.
