The study design was largely cross-sectional, with biological samples collected within a short timeframe.
Certainly the results of our study challenge the notion of seamounts as biological refuges for stony corals within the timeframe expected for climate change effects in the deep sea (i.e. <100 years, [4]).
Drug regimens used in the published studies were diverse, and varied depending on location and timeframe as well as on biological concerns, including those related to the prevalence of glucose-6-phosphate dehydrogenase (G6PD) deficiency.
Basically it is a question of scale, as the same lineage might be viewed as static or evolving towards increased or decreased complexity depending on the level of biological organization (that is, genome, cellular, tissue) or timeframe (deep-time versus recent) one examines.
The timing of divergences among metazoan lineages is integral to understanding the processes of animal evolution, placing the biological events of species divergences into the correct geological timeframe.
Mitochondrial genomes have been widely used in biological research, especially when studying evolutionary and demographic processes that occur over short timeframes [ 1].
Its ability to produce more than one billion sequencing reads within the timeframe of a few days [ 1] has enabled the investigation of tens of thousands of biological events in parallel [ 2, 3].
Hannan uses a dual timeframe.
