Alencar et al. use a macroevolutionary framework to reveal how environmental, life history, and geographical factors interact with thermal tolerance to shape the distribution of the most diverse lizard family from North America.

The manifold hypothesis posits that many high-dimensional datasets actually lie near a low-dimensional manifold. Boyko and Rabosky consider phylogenetic comparative methods, which typically assume a flat, euclidean, morphospace.

Till Selection Do Us Part? Testing Sexual Selection’s Role in Speciation
Summary & Analysis by Pooja Radhakrishnan of "Evolutionary lability of sexual selection and its implications for speciation and macroevolution" by Januario et al.

Simon et al. compared the role of constraints and selection on function to align micro- and macroevolutionary patterns of hindlimb trait covariation in frogs. They inferred that species tracked jumping performance peaks mostly along lines of least resistance within-species. Read now ahead of print!

Januario et al. found no correlation between sexual selection intensity & speciation rates or proxy traits. Because sexual selection intensity has high intraspecific variation and low phylogenetic signal, its macroevolutionary impacts are weak. Read now!

#Evolution refers to change in a biological population's inherited traits from generation to generation. All species on Earth originated by the mechanism of evolution, through descent from common ancestors. Evolution occurs as changes accumulate over generations. Charles Darwin recognized evolution by natural selection, also called "descent with modification", as the fundamental process underlying all of life, whether viewed at a large scale above the level of species (#macroevolution — in terms of formation of new species, changes within lineages, and extinction), or at a small scale within a species (#microevolution — in terms of change in gene frequency). In a nutshell, evolution by natural selection can be simplified to the following principles: 1) Variability 2) Differential Fitness 3) Heredity
