«A
phylogeny and taxonomy is fundamental for all fields of biology that use lizards and snakes, to understand how to classify the
species being studied, to interpret biological patterns in terms of relatedness, and even at a more basic level, to count how many
species are in an area, for example, for conservation management purposes.»

species tree, and thus are not suitable for generating a highly resolved
phylogeny.

phylogeny to identify which genes provide positive support for the divergence of
species.»
Although the diversity of sponges and their uncertain
phylogeny make it doubtful that any single
species can reveal the intricacies of early animal evolution, comparison of the A. queenslandica draft genome with sequences from other
species can provide a conservative estimate of the genome of the common ancestor of all animals and the timing and nature of the genomic events that led to the origin and early evolution of animal lineages.
