Evolution

Recently, my attention has been caught by several interesting articles on evolution that (albeit must be taken cautiously), try to support new hypotheses on evolution :

Larson et al nicely  discuss a possible evolution of dog breeds in the light of results obtained with denser SNP chip.

Nature, spotlight Kevin Peterson’s work which use miRNA in phylogeny.

Both  articles point out the necessary distance one must have regarding informations in hand. As instance, markers or miRNA have certain properties (mutation rate, neutrality, abundance….) that should be taken into account as they will drive our conclusion in one way or another. Another feature nicely shown by Larson et al., is the parallel made between the molecular observations, our knowledge of “breed” history , and the probability that genetic events (bottleneck, admixture) occurred.

On another more humorous side, Brian Malow made some good points in one of his video…evolution might be “a slow process”. 😉
