We used the known branching order of the primate phylogeny, together with a maximum-likelihood approach using different models of evolution, to test whether positive selection has acted on these genes.
Therefore, it can be used as a null model of neutral evolution to test selection hypotheses concerning the evolution of overlapping genes.
The code has been designed to predict the orbital evolution of test particles moving within a fully-analytical gravitational potential generated by a multi-component galaxy.
They then developed a model of viral evolution to test whether existing viruses, once they happen to infect a mammalian host, might accumulate the missing mutations and become excreted in respiratory droplets, which could start a chain of transmission.
Long has used Tadros to study the evolution of backbones, testing the idea that by making ancient fish stiffer, backbones made them faster and hence better at collecting food or evading predators.
We then use a formal approach based on mathematical models describing the dynamics of population size evolution to test potential progeny links and demonstrate that most cells follow a linear naive→early effector→late effector→memory pathway.
The combination of statistical approaches we used, including model fitting and a novel pipeline involving simulations under a stochastic birth-death process, can be readily deployed in future analyses of gene family evolution to test for non-neutrality.
Therefore, it can be used as a null model of neutral evolution for testing selection hypotheses affecting the evolution of overlapping genes.
The evolution of hypothesis testing Statistical-hypothesis testing was a huge leap forward in science.
Landis went so far as to suggest: "He [Armstrong] and I had lengthy discussions about it on our training rides, during which time he also explained to me the evolution of EPO testing and how transfusions were now necessary due to the inconvenience of the new test".
Chapters in this volume also address the evolution of toxicology testing.
