We propose that four criteria should be considered when determining whether evolving genetic material is part of the phylogenetic tree ... is highly regulated. Most DNA viruses, for example ...

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).

scientists used vast amounts of DNA sequencing data and fungal fossils to understand the diversification of fungi, in the context of plants. They created a time-calibrated phylogenetic tree ...
