Rate of evolution of DNA is constant over time and across lineages. Resolve history of species. Timing of events. Relationship of species. Early protein studies showed approximately constant rate of evolution. 1. “. Organic life, we are told, has developed gradually from the protozoon to the philosopher, and this development, we are assured, is indubitably an advance. Unfortunately it is the philosopher, not the protozoon, who gives us this assurance.. 1. 4. 3. 2. 5. 1. 4. 2. 3. 5. Phylogenetic Trees. Nodes: species. Edges: time of independent evolution. Edge length represents evolution time. AKA genetic distance. Not necessarily chronological time. Highlights of what you need to remember:.

Evidence for evolution can come in the form of anatomy and physiology. For example vestigial, analogous, and homologous structures. . Vestigial Structure:. The concept of vestigiality applies to genetically determined structures or attributes that have apparently lost most or all of their ancestral function in a given species. An example is the human appendix..
