The estimation of the timing of evolutionary events from DNA sequence information has become a major research topic in evolutionary biology.
How does Dr. Lenski's E. coli experiment offer a new insight about the timing of evolutionary change?
Estimates published after the discovery of Zachelmie tracks suggested that digited tetrapods may have appeared as early as 427.4 Myr ago and questioned attempts to read absolute timing of evolutionary events in early tetrapod evolution from stratigraphy.
A corollary of the stepwise mutation nature of microsatellite mutations is the fact that we can use microsatellite variability to estimate the timing of evolutionary events.
Moreover, we exemplify how an historical approach can provide potentially important information and help to disentangle the timing of evolutionary events in the history of the Oryza genomes.
Ancient DNA has proved invaluable for the detailed analysis and identification of extinct and morphologically cryptic taxa such as that of quail and can provide insights into the timing of evolutionary changes that influence morphology.
Indeed, the substitution rate used in the molecular clock estimation is critical in assessing the timing of evolutionary events.
Studies seeking to assess the timing of evolutionary events with respect to environmental changes, for example, cannot rely on such results, nor could phylogeographic reconstructions.
We also compared these regions with orthologs in soybean, poplar, Vitis, Arabidopsis, and tomato to help clarify the timing of evolutionary events.
The goal of this study is to estimate the timing of evolutionary events involved in the origin of eukaryotes (Fig. 1), including the related origin of oxygenic photosynthesis.
