Sentence examples for molecular clocks found from inspiring English sources

An entire network of molecular clocks found in the different organs coordinate the body's various physiological processes ranging from the heart beat, temperature, sleep requirement and hormone balance to behavior.

While significant deviations from molecular clock have been found in many taxa, effects of life histories on molecular evolution are not fully understood.

After removing this haplotype (H31), no other violation of the molecular clock constancy was found, so the other 35 haplotypes were used for further analysis.

Comparing multiple molecular clock analyses, we find that the maximum marginal probability for the divergence time of bacterial and eukaryal sterol biosynthesis genes is around 2.31 Gyr ago, concurrent with the most recent geochemical evidence for the Great Oxidation Event7.

Furthermore, phylogenetic analyses of those EVEs shared among different host species revealed extremely complex tree topologies which do not reflect the host phylogeny; these are indicative of independent integration events that again prohibit effective molecular clock dating (please find an example tree in the new Figure 11).

We estimated divergence times within rodents in BEAST using six fossil calibration points and a Bayesian relaxed molecular clock approach [20] and found all rodents to share a common ancestor around 67 mya (CI: 57 76 mya) (Table S4).

Although Burgess and Yang (2008) modeled sequencing errors and violations of the molecular clock, those factors were found to have only minor impact on estimation of parameters concerning the human, chimpanzee, and gorilla in the analysis of the curated data (compare tables 2 and 5 in Burgess and Yang 2008).

We design synthetic molecular clocks having a reduced number of genes and some of them showing architectures found in nature.

But researchers are still arguing over whether molecular clocks tick regularly enough to provide accurate ages.

"So the contradiction between the fossils and molecular clocks remains".

Researchers often estimate the ages of groups using what are called molecular clocks, as was done in the new study.
