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 …

The geochemical carbon cycle is strongly influenced by life on land, principally through the
effects of carbon sequestration and the weathering of calcium and magnesium silicates in …

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 …

Molecular dating of species divergences has become an important means to add a temporal
dimension to the Tree of Life. Increasingly larger datasets encompassing greater taxonomic …

Ecdysozoans have been key components of ecosystems since the early Cambrian, when
trilobites and soft-bodied Burgess Shale-type ecdysozoans dominated marine animal …

Mitochondrial (mt) genes and genomes are among the major sources of data for
evolutionary studies in birds. This places mitogenomic studies in birds at the core of intense …

Haemosporidians are a diverse group of vector-borne parasitic protozoa that includes the
agents of human malaria; however, most of the described species are found in birds and …

Neotropical skinks are unique among lizards and other vertebrates in their degree of
convergence, in reproductive traits, with eutherian mammals. They have also been famously …

Many questions in evolutionary biology require an estimate of divergence times but, for
groups with a sparse fossil record, such estimates rely heavily on molecular dating methods …

The geographic and temporal origins of Madagascar's biota have long been in the center of
debate. We reconstructed a time-tree including nearly all native nonflying and nonmarine …
