Metabolic rate does not calibrate the molecular clock.
Rates of molecular evolution vary widely among lineages, but the causes of this variation remain poorly understood. It has been suggested that mass-specific metabolic rate may be one of the key factors determining the rate of molecular evolution, and that it can be used to derive "corrected" molecular clocks. However, previous studies have been hampered by a paucity of mass-specific metabolic r...
متن کاملMetabolic Rate Calibrates the Molecular Clock: Reconciling Molecular and Fossil Estimates of Evolutionary Divergence
2 Observations that rates of molecular evolution vary widely within and among lineages have cast doubts upon the existence of a single " molecular clock " (1, 2). Differences in the timing of evolutionary events estimated from genetic and fossil evidence have raised further questions about the existence of molecular clocks and their use (3, 4). Here we present a model of nucleotide substitution...
متن کاملThere is no universal molecular clock for invertebrates, but rate variation does not scale with body size.
The existence of a universal molecular clock has been called into question by observations that substitution rates vary widely between lineages. However, increasing empirical evidence for the systematic effects of different life history traits on the rate of molecular evolution has raised hopes that rate variation may be predictable, potentially allowing the "correction" of the molecular clock....
متن کاملExperimentally-Induced Metabolic Acidosis Does not Alter Aortic Fatty Streak Formation in High-Cholesterol Fed Rabbits
Objective(s)Cardiovascular disease causes a major clinical problem in patients with end stage renal disease. Since metabolic acidosis is very common in patients with end stage renal disease, we aimed to investigate the effect of experimentally-induced metabolic acidosis on serum lipid profile and aortic fatty streak (FS) formation in normal and high-cholesterol fed rabbits.Materials and Methods...
متن کاملHigh basal metabolic rate does not elevate oxidative stress during reproduction in laboratory mice.
Increased oxidative stress (OS) has been suggested as a physiological cost of reproduction. However, previous studies reported ambiguous results, with some even showing a reduction of oxidative damage during reproduction. We tested whether the link between reproduction and OS is mediated by basal metabolic rate (BMR), which has been hypothesized to affect both the rate of radical oxygen species...
