Evidence from phylogenetics and molecular clocks to determine the main sequence of events in evolution. The sequence of events can be determined using sequence data and fossil evidence.
Comparison of sequences provides evidence of the three domains of life — bacteria, archaea and eukaryotes.
Phylogenetics is the study of evolutionary history and relationships.
Use of sequence data to study the evolutionary relatedness among groups of organisms. Sequence divergence is used to estimate time since lineages diverged.
Use of sequence data and fossil evidence to determine the main sequence of events in evolution of life: cells, last universal ancestor, prokaryotes, photosynthetic organisms, eukaryotes, multicellularity, animals, vertebrates, land plants.
Molecular clocks are used to show when species diverged during evolution. They assume a constant mutation rate and show differences in DNA sequences or amino acid sequences. Therefore, differences in sequence data between species indicate the time of divergence from a common ancestor.
