Students use both morphology and analysis of DNA sequences to identify relationships between species and to organize species and traits into phylogenetic trees. Along the way, students will watch ...

As such, DNA sequencing has emerged as a fundamental ... The distances are often placed on phylogenetic trees, which show the deduced relationships among the organisms (Figure 3).

These are Jukes-Cantor distances based on number of mtDNA sequence differences. [See Glossary and pp. 91-93 of Hall, B.G. 2001. Phylogenetic Trees Made Easy. Sinauer, for more on evolutionary models ...

Scientists identified two key distinctions related to the DNA replication ... the sequences of multiple genomes of diverse life-forms to construct and compare thousands of phylogenetic trees ...

A team of engineers at the University of California San Diego is making it easier for researchers from a broad range of ...
