Genome engineering and phenotyping in vivo reveal surprising new features of adaptive amino acid substitutions that were previously inaccessible.

Apicomplexan-like parasites originated several times independently and many of them contain cryptic plastid organelles, which demonstrate that the parasites evolved from photosynthetic algae.

Each dengue serotype contains moderate antigenic diversity, and population immunity drives clade turnover in a hyperendemic population.

High reproductive effort constrains bone tissue response to physical activity-induced mechanical loading.

Measurements of bar-headed geese flying in a wind tunnel in hypoxia reveal that these birds sustain aerobic flight at high altitude via a reduction in metabolism.

Sexual differentiation controlled by sex-specific mRNA splicing evolved in a step-wise manner in insects.

Bar-headed geese lower their flight metabolic rates to fly in low-oxygen conditions.

A longer birdsong-learning window evolves in response to sexual selection for song complexity and is associated with faster evolution of song performance characteristics.

A new model describes how adaptive molecular evolution shapes phylogenetic trees and can be used to estimate the fitness effects of mutations from phylogenies.

Single-cell RNA-sequencing in fruit flies gives an unprecedented picture of how new genes are expressed during the formation of sperm.
