It is demonstrated DNA sequence evolution through time and the rate of evolution of the hypervariable region I using a Markov chain Monte Carlo integration and a least-squares regression analysis are approximately two to seven times higher than previous indirect phylogenetic estimates.

A novel gene, ASW (Avian Sex-specific W-linked), which shows female-specific expression in genital ridges and maps to the chicken W chromosome is identified and it is shown that ASW is linked to the W chromosome in each of 17 bird species from nine different families of the class Aves.

Results are in contrast to the view that molecular rates are time dependent, and the rate of evolution of the same HVR I region, determined using DNA sequences from 162 known age sub-fossil bones spanning a 37,000-year period, was 0.7%.

A cycle of lineage-splitting occurred approximately 4-10 million years ago, when the landmass was fragmented by tectonic and mountain-building events and general cooling of the climate, resulting in the geographic isolation of lineages and ecological specialization.

Why Does Insect RNA Look Degraded?

The electrophoretic rRNA profile of insects, using the honey bee, Apis mellifera, as an example, differs significantly from the standard benchmark since the 28S rRNA of most insects contains an endogenous “hidden break.”
Is a large-scale DNA-based inventory of ancient life possible?

This study suggests that DNA barcoding might also help us detect other extinct animal species and that a large-scale inventory of ancient life is possible.
Ancient DNA enables timing of the pleistocene origin and holocene expansion of two adélie penguin lineages in antarctica.

This work reports the presence of two distinct and highly variable mitochondrial DNA lineages and track changes in these lineages through space and time and suggests an important new role for ancient DNA studies in the timing of divergent events in history.
Nuclear DNA sequences detect species limits in ancient moa

- 11 September 2003
The results show that moa were characterized by extreme reverse sexual dimorphism and as a result they have been able to clarify the number of moa species and illustrates that single-locus nuclear DNA sequences can be consistently recovered from ancient material.
