We can estimate this time by comparing molecular sequences in the two species.

Alignment of the letters makes it easier to compare different sequences visually.

In 2010 an analysis compared sequences to phylogenetic trees, and supported the idea of common descent.

Structural alignments can compare two sequences or multiple sequences.

The goal of this project is to compare genetic sequences of different individuals to elucidate similarities and differences within chromosomal regions.

The study compared amino-acid sequences in main chemicals of the various species, with emphasis on those species where the most complete data were available.

By comparing extant sequences, one can determine the amount of sequence divergence.

By comparing genetic sequences, the scientists said they had confirmed that the velvet worm was not the link between the arthropods and the annelids.

By comparing human and mouse sequences, they found that the amino acids near splice sites changed less over time compared to the rest of the protein.

Studies comparing genetic sequences of Riella plants support this relationship.
