From Sequence Comparison to Evolutionary Insight
- DNA sequence comparison augments and sometimes clarifies anatomical comparison.
- Phylogenetic trees, which explain relatedness, can be generated using DNA sequence alignments.
- With increased amounts of sequence data, we have more confidence than ever in the phylogenetic trees that can be generated.
The image is a phylogenetic tree depicting the evolutionary relationships among camels, pigs, ruminantia, hippos, and whales. Whales in the tree are most closely related to hippos.
