Data from: Rapid morphological evolution in placental mammals post-dates the origin of the crown group

- DOI：
- doi:10.5061/dryad.2kp7vr8
- 摘要：
- interpretation of the fossil record and from molecular-clock dating studies. Despite both fossil occurrences and molecular sequences favouring a Cretaceous origin
Data from: Molecular clocks indicate turnover and diversification of modern coleoid cephalopods during the Mesozoic Marine Revolution
- 负责人：
- DOI：
- doi:10.5061/dryad.180nh
- 摘要：
- confident analysis of the tempo and pattern of their evolution. Here we use a molecular dataset (180 genes, approx. 36 000 amino acids) of 26 cephalopod
Data from: Diatoms do radiate: evidence for a freshwater species flock
- 负责人：
- DOI：
- doi:10.5061/dryad.qf0ft85
- 摘要：
- information to test if this group, indeed, constitutes a species flock. Molecular-clock and phylogenetic analyses indicate a young monophyletic group of seve
Data from: Multiple morphological clocks and total-evidence tip-dating in mammals
- 负责人：
- DOI：
- doi:10.5061/dryad.3h4m5
- 摘要：
- n separate clocks, each distinct from the molecular clock. Total-evidence tip-dating using these multiple clocks inflated divergence time estimates, but potent
Data from: Late-glacial demographic expansion motivates a clock overhaul for population genetics
- 负责人：
- DOI：
- doi:10.5061/dryad.3q24t
- 摘要：
- The molecular clock hypothesis is fundamental in evolutionary biology as by assuming constancy of the molecular rate it provides a time frame

- DOI：
- doi:10.5061/dryad.5590q
- 摘要：
- Dated phylogenetic trees are important for studying mechanisms of diversification, and molecular clocks are important tools for studies of organisms
Data from: Temperature-dependent resetting of the molecular circadian oscillator in Drosophila.

- 摘要：
- components in the fruitfly Drosophila melanogaster: the transcripts and proteins for the clock genes period (per) and timeless (tim). The molecular circadian
Data from: Molecular phylogeny and SNP variation of polar bears (Ursus maritimus), brown bears (U. arctos) and black bears (U. americanus) derived

- 摘要：
- ). We reexamined this issue in light of a morphological data set composed of 207 characters and molecular data sets of published 12S, 16S, and cytoc
Data from: The linking of plate tectonics and evolutionary divergences
- 负责人：
- DOI：

- 摘要：
- re recent transoceanic dispersal events. However, molecular clocks can be problematic and we have identified three issues with the analyses of Bauzà-Ribot
