Ancient DNA damage
Under favorable conditions DNA can survive for thousands of years in the remains of dead
organisms. The DNA extracted from such remains is invariably degraded to a small average …

Diverse plant and animal genetic records from Holocene and Pleistocene sediments
Genetic analyses of permafrost and temperate sediments reveal that plant and animal DNA
may be preserved for long periods, even in the absence of obvious macrofossils. In Siberia …

DNA sequences from multiple amplifications reveal artifacts induced by cytosine deamination in ancient DNA
We show that DNA molecules amplified by PCR from DNA extracted from animal bones and
teeth that vary in age between 25 000 and over 50 000 years carry C→ T and G→ A …
