Adaptive radiations generate remarkable morphological diversity, yet traits often diversify at different rates and modes, producing mosaic patterns of evolution. Modularity, the semiautonomous organization of traits, can shape how selection and ...

The major funder of basic science has not said how its new initiatives will be funded — but staff worry streamlined approach will further squeeze cash for core sciences.

By doubling their entire genome, organisms can evolve extremely rapidly — or they can lose it all. New studies reveal how to survive the high-risk, high-reward evolutionary event.

Abstract. The fossil record is incomplete, as evidenced by the pervasive presence of ghost lineages throughout the Tree of Life. For example, across placen

Abstract. Recombination diversifies offspring genomes and helps ensure chromosome segregation during meiosis. Mutation rates are elevated near crossovers d

Over the last year, our lab has been developing a policy on AI use. To do this, we did three main things: We read a lot of academic publications and tech news. We set up an #ai channel on our la...

Sex chromosome evolution is among the most dynamic genomic innovations in vertebrates, yet why some lineages evolve XY while others evolve ZW remains unclear. Using chromosome-level genomes from 19 ge...

Abstract. Convergence, defined as lineages evolving to be more similar to one another than their ancestors due to selective pressures is a hallmark of adap

Abstract. We investigate the evolutionary dynamics of sexually selected traits using both a mathematical model and comparative analyses, focusing on the re
