Wiens [63] suggested that it should be possible to design phylogenetic analyses that will resolve higher - level relationships with large numbers of slow - evolving characters and then place additional taxa on this scaffold through the use of a smaller number of more rapidly evolving characters.

The new phylogenetic analyses use the same model as the original paper but when additional modern Aboriginal and African sequences are added they show that all the ancient Australian sequences are well within what is expected for modern human variation.

Langer calls that approach to phylogenetic analyses «old - fashioned.»

However, the results of more recent phylogenetic analyses, derived from comparisons between sequences of specific genes and of whole genomes, seemed to point to Ctenophora as the first group that parted company with the lineage from which the rest of the animal kingdom (including sponges) evolved.

However, with the development of phylogenetic analyses, we can see speciation at the genetic level (i.e. highly reduced or absent interbreeding between subpopulations) without the distinct morphological differences one would require if phenotypes were the only measure.

Add to this, phylogenetic analyses of both extant and extinct forms corroborate the progression as observed in the fossil record.

From the progressive order of the fossil record, phylogenetic analyses confirming these relationships, to observable instances of speciation and molecular artifacts like our gene for egg yolk protein, the evidence firmly supports evolution.
