Time Dependency of Molecular Evolutionary Rates? Yes and No
Some previous studies have suggested that rates of evolution inferred using molecular sequences vary substantially depending on the time frame over which they are measured, whereas a number of other studies have argued against this proposition. We examined this issue by separating positions of primate mitochondrial genomes that are under different levels of selection constraints. Our results re...
متن کاملGeological dates and molecular rates: fish DNA sheds light on time dependency.
Knowledge of DNA evolution is central to our understanding of biological history, but how fast does DNA change? Previously, pedigree and ancient DNA studies--focusing on evolution in the short term--have yielded molecular rate estimates substantially faster than those based on deeper phylogenies. It has recently been suggested that short-term, elevated molecular rates decay exponentially over 1...

متن کاملNon-Destructive Sampling of Ancient Insect DNA
BACKGROUND A major challenge for ancient DNA (aDNA) studies on insect remains is that sampling procedures involve at least partial destruction of the specimens. A recent extraction protocol reveals the possibility of obtaining DNA from past insect remains without causing visual morphological damage. We test the applicability of this protocol on historic museum beetle specimens dating back to AD...
متن کاملConcurrent Data Structures Linked in Time (Artifact)
This artifact provides the full mechanization in FCSL of the developments in the companion paper, “Concurrent Data Structures Linked in Time”. In the latter, we propose a new method, based on a separation-style logic, for reasoning about concurrent objects with such linearization points. We embrace the dynamic nature of linearization points, and encode it as part of the data structure’s auxilia...
