What is the molecular clock? Levels of molecular variation could be used, in principle, to estimate divergence times, serving as evolutionary "clocks" that "tick" at different rates. Subsequent ...

In the early days of molecular evolution, one of the most tantalizing findings was the observation that protein sequence change seemed to occur at a rate proportional to the time since the ...

Their key innovation was to use the GOE itself as a time boundary, assuming that most aerobic (oxygen-using) branches of bacteria are unlikely to be older than this event—unless fossil or genetic ...

A new genomic study has uncovered long-lost genetic diversity in mammoth lineages spanning over a million years, providing ...

Weinig. 2019. The effect of rhizosphere microbes outweighs host plant genetics in reducing insect herbivory. Molecular Ecology 28 (7) 1801-1811 Rubin, M.J., M.T. Brock, S.J. Davis, and C. Weinig. 2019 ...

The Department of Molecular and Human Genetics at Baylor College of Medicine is transforming medicine by expanding the role of genetics and genomics in science and medicine through major discoveries ...

branches of bacteria are unlikely to be older than this event—unless fossil or genetic signals strongly suggest an earlier origin. Using Bayesian statistics, they created a model that can ...

The team developed and applied an improved molecular clock dating framework, refining how genetic data can be used to estimate the ages of specimens beyond the radiocarbon dating limit.

A new genomic study has uncovered long-lost genetic diversity in mammoth lineages spanning over a million years, providing new insights into the evolutionary history of these animals.
