The molecular clock presents a means of estimating evolutionary rates and timescales using
genetic data. These estimates can lead to important insights into evolutionary processes and …

Five decades have passed since the proposal of the molecular clock hypothesis, which
states that the rate of evolution at the molecular level is constant through time and among …

Phylogenies provide a useful way to understand the evolutionary history of genetic samples,
and data sets with more than a thousand taxa are becoming increasingly common, notably …

The fossil record suggests a rapid radiation of placental mammals following the Cretaceous–
Paleogene (K–Pg) mass extinction 65 million years ago (Ma); nevertheless, molecular time …

We present a phylogenetic and phylogenomic overview of the Polyporales. The newly
sequenced genomes of Bjerkandera adusta, Ganoderma sp., and Phlebia brevispora are …

Molecular evolutionary rate estimates have been shown to depend on the time period over
which they are estimated. Factors such as demographic processes, calibration errors …

The molecular clock provides a powerful way to estimate species divergence times. If
information on some species divergence times is available from the fossil or geological …

Oakleaf butterflies in the genus Kallima have a polymorphic wing phenotype, enabling these
insects to masquerade as dead leaves. This iconic example of protective resemblance …

Background Terpenoids are abundant in the foliage of Eucalyptus, providing the
characteristic smell as well as being valuable economically and influencing ecological …

Background Although hybridization is thought to be relatively rare in animals, the raw
genetic material introduced via introgression may play an important role in fueling …
