. This places limits on what analyses can achieve. Furthermore, due to degradation of the DNA molecules, a process which correlates loosely with factors such as time, temperature and presence of free water, upper limits exist beyond which no DNA is deemed likely to survive. Current estimates suggest that in optimal environments, i.e. environments which are very cold, such as permafrost or ice, an upper limit of max 1 Million years exists. As such, early studies that reported recovery of much older DNA

s, increasing with time. Some regions of polynucleotide are more susceptible to this degradation so sequence data can bypass statistical filters used to check the validity of data. Due to sequencing errors, great caution should be applied to interpretation of population size. Substitutions resulting from deamination cytosine residues are vastly overrepresented in the ancient DNA sequences. Miscoding of C to T and G to A accounts for the majority of errors.

Antediluvian DNA studies

The post-PCR era heralded a wave of publications as numerous research groups tried their hands at aDNA. Soon a series of incredible findings had been published, claiming authentic DNA could be extracted from specimens that were millions of years old, into the realms of what Lindahl (1993b) has labelled Antediluvian

Then, in 1994 and to international acclaim, Woodward et al. reported the most exciting results to date -mitochondrial cytochrome b sequences that had apparently been extracted from dinosaur bones dating to over 80 million years ago. When in 1995 two further studies reported dinosaur DNA sequences extracted from a Cretaceous egg (An et al. 1995; Li et al. 1995) it seemed that the field would truly revolutionise knowledge of the Earth’s evolutionary past.

Pathogen and microorganism a DNA analyses using human remains

The use of degraded human samples in aDNA analyses has not been limited to the amplification of human DNA. It is reasonable to assume that for a period of time post mortem, DNA may survive from any microorganisms present in the specimen at death.
